MIG, TIG, and Stick are the main welding machine types for joining metal; plasma cutters cut metal instead. Choose a process based on the material, thickness, work location, and kind of joint you need.
A multi-process welder can combine some welding modes, but each mode may need specific accessories. If you're choosing a machine for a specific job, see our guide to welding machines for pipeline work.
What are the main welding machine types?
MIG, flux-core, Stick, and TIG are the main welding processes. Plasma cutters belong in the same buying conversation, but they cut metal rather than weld it.
| Process or tool | How it works | Common fit |
|---|---|---|
| MIG | Feeds wire through a gun; shielding gas is commonly used | Shop fabrication and general projects |
| Flux-core | Feeds tubular wire that provides shielding | Projects where gas shielding is inconvenient |
| Stick | Uses a coated electrode held in an electrode holder | Maintenance, outdoor work, and repairs |
| TIG | Uses a non-consumable tungsten electrode; filler rod may be added separately | Controlled work where precision matters |
| Plasma cutter | Uses a plasma arc to cut conductive metal | Cutting parts before fabrication |
These are broad comparisons, not guarantees about weld quality or suitability. The right setup depends on the machine, consumables, material, joint, and operator skill.
Which welding machine types work with more than one process?
Multi-process machines combine two or more welding modes in one unit. The modes vary by machine, so check the controls and required accessories before choosing one.
The YESWELDER 160A MIG Welder offers Flux Core MIG, Gas MIG, Stick, and Lift TIG modes. Its Lift TIG mode requires a separately purchased torch.
The ARCCAPTAIN MIG200 combines gas and gasless MIG, Stick, Spot welding, and Lift TIG, with a spool gun connector. Its TIG gun and spool gun are not included.
More modes do not automatically mean a better fit. If you mainly use one process, compare that mode's controls, accessories, and power needs first.
How does MIG welding work, and when does it fit?
MIG feeds a continuous wire electrode through a welding gun, making it a practical choice for many general shop projects. The process usually uses shielding gas, while flux-core wire is an option on some machines.
With gas MIG, shielding gas protects the weld area. Flux-core wire can provide shielding without a separate gas cylinder, which can simplify setup when moving between locations.
MIG can suit fabrication, DIY projects, and automotive work, but the machine and setup must match the material and joint. Thin sheet needs careful settings and technique to avoid burn-through.
The YESWELDER 160A MIG Welder offers gas MIG and flux-core modes, plus Stick and Lift TIG. It has 110V/220V input and synergic controls that recommend voltage and wire-feed speed based on selected thickness or amperage.
If aluminum is part of your plan, check the wire-feeding setup and torch options before choosing. Our guide explains whether you can weld aluminum with a MIG welder.
The ARCCAPTAIN MIG200 supports solid-wire MIG, flux-core, Stick, Spot welding, and Lift TIG. Its TIG gun and optional spool gun are not included.
Choose MIG when wire-feed welding suits your projects and you can provide the required power and shielding setup. Compare MIG versus Stick welding if you're deciding between those two processes.
What makes flux-core different from gas MIG?
Flux-core feeds wire with a core that helps shield the weld, while gas MIG relies on an external shielding gas supply. The choice affects setup and where you can work, but neither process is right for every material or job.
Some machines support both methods. The YESWELDER 160A MIG Welder supports gas MIG and flux-core modes and accepts solid-core and flux-core wire in .030 in and .035 in sizes.
Flux-core can be useful where managing a gas cylinder is impractical. Gas MIG may suit work where its shielding setup is available and appropriate.
Check the machine's supported wire type and size, drive rolls, and torch setup. Also check the process instructions for the material and position you plan to weld.
How does Stick welding work, and who should consider it?
Stick welding uses a flux-coated rod, called an electrode, held in an electrode holder. It can suit outdoor and maintenance work, though slag cleanup and electrode changes are part of the process.
Stick equipment can be compact, and the process does not rely on an external shielding-gas cylinder. Wind can still affect a weld, so outdoor work needs sound setup and judgment.
The ARCCAPTAIN 200A Stick Welder offers Stick and Lift TIG modes. It supports 6010, 6011, 6013, and 7018 rods, and its Lift TIG torch is not included.
Stick welding can suit repairs, farm maintenance, and outdoor projects where a wire-feed setup is less convenient. It takes practice to strike and maintain an arc and to manage slag.
Choose Stick if its portability and outdoor use match your work. For more detail on whether this process fits your shop, read Stick welding and TIG welding compared.
What is TIG welding best suited to?
TIG uses a tungsten electrode to form the arc, while filler metal can be added separately when needed. It gives the operator fine control, but it also demands coordination and a clean setup.
TIG is often chosen for work where bead control and appearance matter. Results depend on the material, joint preparation, settings, and skill, so the process is not a shortcut to a clean weld.
The YESWELDER TIG-205P offers Stick, DC TIG, and Pulse TIG modes, with high-frequency arc starting and dual-voltage input. It cannot weld aluminum.
Check the exact TIG mode and material limits before buying. DC TIG does not mean the machine can weld every metal; confirm that the process supports your material.
Is a plasma cutter a welding machine?
A plasma cutter is a cutting tool, not a welding process. It uses an electric arc and gas to cut conductive metal, so it can prepare parts for a weld but does not join them.
A cutter may suit a shop that regularly shapes sheet or plate. Before choosing one, compare its rated cutting capacity with the metal you plan to cut and check the air supply it requires.
Our guide covers whether a plasma cutter needs an air compressor. For a material-specific limit, see how thick a plasma cutter can cut, and use the maker's rated figures for the exact model.
What should you compare before buying a welder?
Compare process, power, material, workload, and accessories before focusing on output numbers. The machine has to fit your actual work and the place where you'll use it.
How do you match welding machine types to your work?
Start with the materials and jobs you expect to handle. A repair welder for outdoor maintenance may call for a different process from a machine for controlled shop fabrication.
Then check the metal thickness and joint types you expect to work on. Use the maker's output range and instructions to confirm fit; don't infer capacity from the machine's headline amperage alone.
How do you check input power and duty cycle?
Confirm which input voltage the machine accepts and what power is available at your work area. A dual-voltage label does not tell you whether a particular outlet or circuit is suitable for every setting.
Duty cycle describes how long a welder can operate within a stated period at a given output before it needs to cool. Compare the rating at the output you expect to use; our guide explains how much duty cycle you need in a welder.
How do you confirm what's included?
Check which accessories are included or sold separately for the process you plan to use. Torches, spool guns, gas hoses, regulators, and other accessories can vary by machine.
The YESWELDER 160A needs an extra Lift TIG torch for that mode. The ARCCAPTAIN MIG200 needs a separate TIG gun or spool gun for those options.
How many welding processes will you use?
A multi-process welder can save space when you regularly switch between its supported modes. It also adds controls and accessories to learn, so compare it with a simpler machine that matches your main process.
If you're weighing the trade-off for home use, read whether a multi-process welder is worth it.
Which welding machine type should you choose?
Choose MIG for general wire-feed work, Stick for repair jobs, TIG for controlled welding, and a plasma cutter when you need to cut metal. Pick a multi-process machine when you have a clear use for several modes and have confirmed the accessories and power requirements.
Start with your next few projects, then confirm material, thickness, and work location against the maker's guidance. If you already know which process you need, compare the relevant machines in our MIG welders guide, Stick and TIG guide, or plasma cutter guide.
Frequently asked questions
What are the main types of welding machines?
The main welding machine types are MIG, flux-core, Stick, and TIG. MIG feeds wire and typically uses shielding gas, while flux-core uses tubular wire that can be used without external shielding gas.
Stick uses a coated electrode, and TIG uses a separate filler rod when needed.
Plasma cutters cut metal rather than weld it.
Which type of welding machine is easiest for beginners?
MIG is often a practical first process for home projects because the machine feeds wire as you weld. Setup still matters: match the wire, shielding method, material, and power supply to the job, then learn safe technique and practice on suitable scrap.
Some machines offer guided or synergic settings, but they don't replace instruction.
Can one welding machine do several processes?
Yes. Multi-process welders combine selected processes, often MIG, Stick, and Lift TIG, in one machine.
The exact modes and included accessories vary, so check whether a torch or spool gun is extra and whether the machine supports the material and work you have in mind.
Is a plasma cutter a welding machine?
A plasma cutter is a metalworking machine, but it cuts rather than joins metal. It uses a plasma arc to make a cut through conductive material.
If you need to attach two pieces, choose a welding process; if you need to separate or shape metal, compare plasma cutters and other cutting tools.
What should I check before choosing a welder?
Start with the process your project needs, then check the material, thickness, available input power, and whether you will work indoors or outside. Compare the machine's stated output and duty cycle for your planned workload, and confirm which torches, cables, or other accessories are included or sold separately.
