How we compared welders for aluminum and steel

A good welder for aluminum and steel needs a clear process path for each metal. We compared the stated process options, input voltage, aluminum setup and included accessories.

Our score weighs specs and features against what you're shopping for. A machine with AC TIG or spool gun MIG ranks ahead for aluminum-specific work, while portable stick models fit narrower steel repair needs.

Aluminum and steel require different setups, so don't assume that a welder mentioning both metals can do every job with its standard accessories. Check whether a spool gun, TIG torch or other required gear is included, and match the process to the material and joint.

Best welders for aluminum and steel by shop task

The top choices cover a broad mix of processes, aluminum focused TIG and portable steel repair. Choose the machine that fits the jobs you actually do most.

1

YESWELDER 205A MIG Welder: Best for switching between shop processes

9.6/10Our score

• 110V/220V dual voltage
• Gas MIG, flux core MIG, spool gun MIG, lift TIG and stick
• Spool gun and lift TIG torch required separately

This dual-voltage machine combines several steel processes with spool gun MIG for aluminum. The spool gun and lift TIG torch are extra purchases.

See it on Amazon

Pros

• Five process options
• Spool gun aluminum MIG
• Synergic and manual MIG controls

Cons

• Spool gun required for aluminum MIG
• Lift TIG torch required for lift TIG

The YESWELDER 205A earns the top spot because it covers five processes and accepts both 110V and 220V input. For steel, you can choose gas MIG, flux core MIG, stick or lift TIG, depending on the setup and job.

For aluminum, its spool gun MIG mode is the key feature. The spool gun is required separately, so include that accessory when planning the machine and setup.

Synergic MIG matches voltage to a recommended value when you adjust wire speed. You can fine tune voltage from that point, or use manual settings for more direct control.

The machine's 200A output and dual voltage make it the most flexible choice in this group for shops that work across materials. If your aluminum work is mainly detailed or thin material, compare it with an AC/DC TIG welder for aluminum.

Buy it for a mixed-material shop that wants MIG and stick in one machine, with a spool gun available for aluminum. It is less suited to someone who wants an aluminum TIG setup ready without buying more equipment.

2

FEMEROL Plasma Cutter Welder Combo 200A Gas: Best for welding and cutting

9.5/10Our score

• Flux MIG, gas MIG, HF TIG, stick, plasma cutting and spot welding
• Dual voltage
• Maker states 10 mm clean cut and 16 mm maximum severance cut at 220V

This combination machine covers several welding processes and cutting, including aluminum among the metals it can cut. Its broad set of functions suits a shop that needs both jobs.

See it on Amazon

Pros

• Six functions
• HF TIG start
• Maker says it cuts aluminum

Cons

• 42 lb machine
• Requires compressed air for plasma cutting

The FEMEROL combines welding and plasma cutting in one machine. Its six functions include gas and flux MIG, HF TIG, stick, spot welding and cutting.

For a shop that handles both aluminum and steel, the process range is useful, and the maker says the cutter works on aluminum, stainless steel, alloy steel, mild steel and copper. It states a 10 mm clean cut and 16 mm maximum severance cut at 220V.

The package includes a MIG torch, plasma torch and consumables, HF TIG torch and consumables, air filter regulator, gas hose and other accessories. That makes it a broad setup, but it also means a 42 lb machine with more equipment to arrange and maintain.

Buy it if cutting is part of the workload alongside welding. If you mainly need a welder, a simpler machine may leave fewer functions unused.

3

ARCCAPTAIN MIG205MP MIG Welder with Plasma Cutter: Best for many processes in one unit

9.3/10Our score

• Gas MIG, gasless MIG, cut, DC HF TIG, DC lift TIG, stick, clean, spot and spool gun aluminum welding
• Dual voltage
• Spool gun required separately

The nine-mode machine includes spool gun aluminum welding alongside steel processes. It offers app controls and parameter memory, though the spool gun must be bought separately.

See it on Amazon

Pros

• Nine welding modes
• App control and preset memory
• Dual voltage

Cons

• Spool gun required for aluminum
• 46.2 lb machine

The ARCCAPTAIN MIG205MP groups nine modes, including gas and gasless MIG, DC TIG, stick, spot welding, cleaning and plasma cutting. For aluminum, it supports spool gun welding, but the spool gun is an extra purchase.

Its dual voltage accepts 120V or 240V, and the machine includes app control, parameter adjustment and saved settings. The maker says it can store custom presets, which may help when you switch between repeat jobs.

For steel, the wide range of MIG and DC TIG settings gives you more process options than a basic stick machine. The machine weighs 46.2 lb, so consider how often it needs to move around the shop.

Buy it for multiple processes and saved setup control, especially if you also need cutting. If your main goal is aluminum TIG, an AC/DC machine is a more direct match.

4

ARCCAPTAIN TIG Welder AC/DC 200A with Pulse: Best for controlled aluminum TIG

9.0/10Our score

• AC/DC TIG and stick modes
• AC pulse options
• Maker states it welds aluminum from 0.5 mm to 5 mm

AC TIG is the process match for aluminum alloys, while DC TIG handles steel work. Pulse and waveform controls give you more settings for heat and arc behavior.

See it on Amazon

Pros

• AC and DC TIG
• Pulse and waveform options
• Stick mode included

Cons

• Foot pedal not included
• 42.7 lb machine

This ARCCAPTAIN TIG machine is the clearest choice here for aluminum TIG. It offers AC TIG and AC pulse options, with DC TIG settings for steel such as stainless and carbon steel.

The maker gives an aluminum thickness range of 0.5–5 mm and says its square waveform can help clean aluminum oxide film. It also provides adjustable parameters such as AC frequency, AC balance and pulse frequency for users who want detailed control.

The foot pedal is not included, so account for that if remote amperage control matters to your work. Its process focus is TIG and stick, rather than the faster wire feed workflow of MIG.

Buy it for controlled aluminum and steel TIG work, particularly where settings and finish matter more than MIG speed. For process details and other models, see our best TIG welder for aluminum guide.

5

DEKOPRO 110/220V MMA Welder: Best for portable steel repairs

8.0/10Our score

• 110V/220V input
• MMA stick process
• Hot start and anti-stick

This compact stick welder supports steel and stainless work, with hot start and anti-stick functions. The maker also names aluminum among compatible materials, but stick is generally a less direct route for aluminum than AC TIG or spool gun MIG.

See it on Amazon

Pros

• Dual voltage
• Hot start and anti-stick
• Compact carry design

Cons

• Stick process only
• No aluminum-specific setup details

The DEKOPRO is a compact MMA stick welder for repair jobs. It accepts 110V or 220V input and includes hot start, anti-stick and arc stability features.

The maker names mild steel, stainless steel, cast iron and aluminum among compatible materials. Still, this is a stick machine without the aluminum focused features of AC TIG or spool gun MIG, so treat aluminum as a specialized job that requires suitable rods and technique.

Its carry handle and compact design suit work that moves between locations. The package includes an electrode holder, work clamp, adapter cable and brush.

Buy it for portable steel repairs where stick welding is the priority. If aluminum is a regular part of the workload, choose a machine designed around TIG or spool gun MIG.

6

Hpoouo 200Amp 20PCS Rods Stick Welder: Best for a portable starter kit

7.8/10Our score

• 110V stick welder
• 20 welding rods included
• Maker names cast iron and mild steel

This small kit is aimed at home repairs and DIY, with rods and basic accessories included. Its stated material examples focus on steel and cast iron, so it is not the aluminum pick in this group.

See it on Amazon

Pros

• Compact machine
• Rods included
• Hot start and anti-stick

Cons

• Steel-focused material examples
• 110V input only

The Hpoouo is a small 110V stick machine packaged with 20 rods, gloves and chip hammers. It is aimed at home repair and DIY, with a stated current range of 20–200A.

Its material examples include mild steel and cast iron, and its instructions name particular rod types. The data does not guarantee an aluminum setup, so consider this a steel oriented option rather than a general aluminum welding machine.

Hot start, anti-stick and arc force functions are included. At 3.7 lb according to the maker, the unit is easy to carry between a garage and a repair location.

Buy it for basic steel repairs and a compact starter kit. Look elsewhere if aluminum work is a core requirement.

7

Saker Portable Electric Welding Machine: Best for light, mobile steel jobs

7.5/10Our score

• 110V input
• 20–120A adjustable output
• Supports 3/32 in rods

The handheld format and adjustable current suit small repair jobs where carrying space matters. Its material examples include carbon steel and iron, not aluminum.

See it on Amazon

Pros

• 3.3 lb machine
• Five-step current adjustment
• Hot start

Cons

• Steel and iron focus
• Limited to 120A

The Saker handheld welder has a 20–120A range and uses 110V input. Its compact form and 3/32 in rod support suit small repair tasks where carrying a conventional machine is inconvenient.

The maker describes use with carbon steel and iron. It does not name aluminum as a supported material, so this is a narrow steel and iron pick rather than an all material machine.

A five speed current knob sets output, and the welder includes hot start. The stated machine weight is 3.3 lb, which can help for mobile work.

Buy it for light steel or iron repairs where portability comes first. Its limited output range and material focus make it a poor fit for a shop needing regular aluminum work.

8

TOOLIOM 135A 110V Stick Welder Kit: Best for stick and lift TIG basics

7.3/10Our score

• Stick and lift TIG
• 110V household power
• Torch, rods and gloves included

This kit adds lift TIG to a 110V stick machine and includes a torch, rods and gloves. It can suit steel work, but it lacks the AC TIG or spool gun setup that makes aluminum welding more straightforward.

See it on Amazon

Pros

• Lift TIG torch included
• Stick and TIG options
• Carry strap

Cons

• 110V input only
• No AC TIG or spool gun MIG

The TOOLIOM combines stick and lift TIG in a 110V kit. It includes a lift TIG torch, E6013 rods, gloves and a shoulder strap.

Lift TIG can serve some steel work, while stick gives you another option for repairs. This model does not provide AC TIG or a spool gun MIG mode, so it lacks the aluminum setup highlighted in the higher ranked picks.

The LCD shows welding data, and VRD, hot start and arc force functions are included. At 135A, it is a lower output choice for modest tasks.

Buy it for a basic stick and lift TIG setup for steel work on household power. For focused TIG choices, read our best welding machine for stainless steel guide.

9

WRDLOSY 250A Stick Welder 110V: Best for steel-only home repairs

7.0/10Our score

• 110V stick welder
• 20–250A peak setting
• Maker says it is not suitable for aluminum

This portable kit is designed for steel, iron and stainless repairs. The maker explicitly says it is not suitable for aluminum, so choose it only when aluminum is outside the job list.

See it on Amazon

Pros

• Portable kit
• Hot start and arc force
• Rods and gloves included

Cons

• Not suitable for aluminum
• 110V input only

The WRDLOSY is explicitly a steel repair machine, not an aluminum pick. Its maker says it is not suitable for welding aluminum, so keep it off the shortlist if both metals are required.

For steel and iron, the 110V kit includes rods, gloves, a brush and an electrode holder. Hot start and arc force are included to help strike and maintain an arc, and the maker distinguishes a 250A peak setting from 150A effective output at 110V.

It is a compact option for home repairs, with a stated machine weight of 3 lb before accessories. Use the maker's guidance on circuit needs and rod polarity when setting up.

Buy it for steel-only home repairs when a small stick kit meets the job. If aluminum is also on your materials list, consider an aluminum stick welder guide and verify the process and consumables before you commit.

Which welding machine process suits aluminum and steel?

AC TIG is a strong fit for precise aluminum work, while MIG can suit faster production and general shop fabrication. For steel, MIG, TIG and stick all have useful roles, so start with the material, thickness and finish you need.

Is a MIG welder for aluminum and steel the most flexible choice?

A MIG welder can be flexible when it supports an aluminum spool gun and the right steel setup. The YESWELDER and ARCCAPTAIN MIG205MP both include spool gun aluminum modes, but their spool guns must be purchased separately.

A spool gun feeds aluminum wire close to the torch, which can help with wire feeding. Compare MIG welders for aluminum and MIG welders with an aluminum spool gun if MIG is your preferred process.

Pulse MIG is another path for shops comparing aluminum wire processes. See our pulse MIG welder guide for aluminum for that specific setup.

When should you choose AC/DC TIG?

Choose AC/DC TIG when you want TIG control on both aluminum and steel. AC is the key mode for aluminum in the TIG machine here, while DC TIG covers steel work.

TIG typically asks more from the operator than simply selecting a mode. A foot pedal can also matter for fine current control, and the ARCCAPTAIN's pedal is not included.

Use our welding machine selection guide to weigh process, power and job type. If portability matters most, compare a portable aluminum welder with the larger shop machines.

What should you check before buying an aluminum welding machine?

Check the process, voltage, accessories and the thickness range you expect to weld. An aluminum welding machine needs more than a broad material label to match your work.

First, confirm whether the machine supports AC TIG or spool gun MIG for your intended aluminum jobs. Then check whether the required torch or spool gun is included, because some machines need separate accessories.

Next, compare the input voltage with the circuits available in your shop. Dual voltage can give you options, but it does not replace checking the machine's output and the job's power needs.

Finally, plan for compatible filler material, shielding gas where required, cleaning and safe setup. Welding requires suitable eye, skin and respiratory protection, as well as training and ventilation suited to the material and process.

Verdict: which welder should you choose for aluminum and steel?

Choose the YESWELDER 205A if one multi-process machine should cover MIG and stick steel work plus spool gun aluminum MIG. Pick the ARCCAPTAIN AC/DC TIG for controlled aluminum TIG and steel TIG, or the FEMEROL if plasma cutting belongs in the same shop setup.

For steel-only mobile repairs, the DEKOPRO or smaller stick machines cost less in space and complexity. If you're considering a Hobart Handler 140 for aluminum MIG, check the Hobart Handler 140 spool gun guide before buying accessories.

Choose by the aluminum process you will use most, then verify voltage and included accessories. That gives you a more reliable match than choosing on a machine's process count alone.

Frequently asked questions

What process is best for welding aluminum and steel?

AC TIG is a strong choice when you need controlled aluminum welds and detailed work on steel. A multi-process machine with spool gun MIG can handle both materials with a faster wire process, while a basic stick welder is better suited to steel repairs.

Match the process to material thickness, joint access and finish needs.

Can one welder handle both aluminum and steel?

Yes, if it supports a suitable process for each metal. Look for AC TIG, spool gun MIG or another aluminum-ready setup, plus a process you want for steel such as MIG, TIG or stick.

Check what torches or spool guns are sold separately before choosing a machine.

Is a stick welding machine for aluminum a good choice?

Stick welding aluminum is possible with the right rods and technique, but it is not the simplest choice for most shops. AC TIG or spool gun MIG gives many users a more direct aluminum setup.

For occasional steel work, a stick machine can still be a practical, focused tool.

Do I need 220V to weld aluminum?

Not for every job, but available input power affects the machine and work you can take on. Several picks here accept dual voltage, while others are 110V only.

Check the machine's requirements and the circuit available in your shop before buying, then compare the output range with the material and thickness you plan to weld.
