Relationship between Plasma Cutter and MIG Welder

When it comes to welding elaborate joints, MIG stands apart from the rest as a result of its vast application and also ease of usage. On the other hand, when it concerns puncturing metals quickly as well as with unprecedented agility, a plasma cutter has no peers. Yet what's the partnership in between plasma cutter as well as MIG welder? Can you utilize MIG welder as a plasma cutter without purchasing a multi-purpose maker? Initially, glance, plasma cutter as well as MIG welder might appear similar. You can get your answers fo your questions here at welding tools geek.  Both involve heats and electric arcs. Nevertheless, both vary substantially both functionally as well as conceptually.

Differences in between Plasma Cutter and also MIG Welder

What is a plasma cutter?

A plasma cutter is a device that uses a torch in the kind of an accelerated jet of hot plasma to puncture electrically conductive materials. The plasma is created when gas is passed through a restricted opening (lantern) at a very high speed forming an electric arc on the degree listed below.

The plasma cutter then uses the electrical arc as well as gas to create precise, tidy, and expert cuts. The gas can be Argon, Nitrogen, Oxygen, or shop air, relying on the metal being cut. Most entry-level plasma cutters make use of store air just fed through an air compressor. High accuracy plasma cutters such as those located in complex construction stores need pressurized gas such as Argon or a mix of gases.

The products that can be reduced with a plasma cutter include lightweight aluminum, steel, stainless steel, copper, brass, among other conductive metals. Because of high speed as well as very warm local "cone", a plasma cutter is utilized to cut sheet metal with angled or bent forms, as well as it is commonly used in large CNC applications and also little DIY stores.

When utilizing MIG welder or any kind of another welder, the inside of the steel continues to be warm, however, when utilizing plasma, the inside of the metal stays cool. The plasma cutter is also practically ten times faster than MIG welder, and also it is effective in reducing slim and thick metals alike. A hand-held plasma cutter can be made use of to cut up to a 1.5-inch thick steel plate. On the other hand, more powerful computer-controlled plasma torches can cut up to 6 inches making them extremely valuable for cutting thick steel plates.

As talked about above, the materials reduced by a plasma cutter require more voltage supply for reducing without dross cuts. However, on an occasion the cut-rate slow off, the treatment can lead to the deposition of thick, porous particles leading to an impure cut side, however it simple to remove.

MIG Welder
Basically, a MIG welder is used to produce an electric arc between a consumable electrode and also the workpiece metal (s), which warms the steels, causing them to thaw and also join, therefore developing the weld. Along with the wire electrode, MIG welder likewise uses a shielding gas, which is feed through the welding weapon to protect the process from atmospheric contaminants.

The efficiency of MIG welder is dependent on the feed rate and also choosing the ideal gas. If the two are not set appropriately, the steels being bonded will not melt. MIG welder produces less heat than a plasma cutter, which indicates much less steel flexing. This makes it excellent for welding slim metals such as autobody work as well as slender sheet steel.

The MIG welder is extensively made use of by hobbyists, farmers, electric motor enthusiasts, or musicians to make almost every kind of construction as well as repair/maintenance tasks. It can weld material from gauge 24 approximately 1/2- inch thick, and also most individuals locate it simple to find out by simply complying with some crucial ideas.

Can I use MIG welder as Plasma Cutter?

Plasma cutters have actually gotten appeal over the previous years, and they have actually come to be a tool of option for reducing different steels. They are tidy, quick, and also very easy to operate than the traditional oxyacetylene torches. Nevertheless, if your job does not entail lots of cuts and you do not intend to invest in a plasma cutter, you can convert your MIG welder to generate cuts comparable to those of a plasma cutter. For this you'll require;

  • Copper tubes
  • Carbon electrode
  • Drill
  • Brass hardware( brass pipes shutoff as well as brass cap).
  • Zip ties.
  • Faucet and also die.
  • Brass jet.
  • An air compressor.

Connect the brass cap cup on one end of the copper tube as well as the plumbing valve on the various other ends of the copper tube. You will then require to pierce a hole in your cap that will be made use of to run strings comparable to a tiny brass carburetor jet. On the various other hands, the plumbing shutoff will enable you to readjust the air volume.

Connect your tubes onto the welder manage as well as protect it securely utilizing the zip connections. Put a carbon electrode instead of welding wire and also guarantee that the idea of the electrode is sharp and also in the cone-shaped form (similar to a sharp pencil) after that bent the nozzle towards the idea of the electrode.

Currently, on the brass plumbing shutoff, connect a fast-releasing compressor hose coupling for your air compressor. You'll after that need to establish the amperage of your welder up to 25-50 amps. This will certainly create a very warm arc, resulting in excessive oxidation efficient in blowing via a metal plate as much as one inch thick like in a plasma cutter.


This experiment requires a little technique for optimal efficiency. You'll additionally need to take care of the air stream to stay clear of blowing some towards you or others. You'll likewise require to wear a welding safety helmet for eye and face protection. Additionally, when dealing with a plasma cutter, make certain to work in a well-ventilated or open space given that it generates dangerous fumes. Remember, the benefit of plasma cutters is that they do not ignite upon heating up, and the steel does not fume while reducing. Also, cutters are more effective than MIG welders because of their speed.
