Gas and Gasless MIG Welders for DIY & Industrial Use

MIG welder are commonly used as they are fast and efficient. They use a metal wire to create an electrical welding arc which melts the wire. The MIG / MAG process uses a protective gas to give a smooth & consistent weld. Pulse & double pulse MIG welders have become popular in recent times as they give a perfect result on all materials, especially stainless steel & aluminium.

We have MIG welding machines that are MIG only type. We have have multi process MIG welders that do MIG, TIG & MMA.

Understanding MIG Welding

Metal Inert Gas (MIG) welding is a universal welding technique suitable for a wide range of materials, from thin-gauge sheet metal to heavier steel. The versatility of MIG welding lies in its wire feed mechanism, eliminating the need for a separate tank of shielding gas. This makes it an ideal choice for welders working on diverse projects.

How does a MIG welder work?

A Mgder MIG welder operates by feeding a wire from a spool within the unit to create the weld. The wire, controlled by a trigger on a spool gun, is fed through a copper contact tube that conducts current. Simultaneously, shielding gas is fed through a nozzle around the wire, protecting the weld pool from the surrounding atmosphere. The motor-driven reel inside the MIG welder ensures a continuous feed of wire as the operator moves the welding gun along the joint line. The welding wires, either solid or cored, act as a heat source and filler metal for the weld joint. Many Mgder MIG welders allow operators to select wire diameter and metal thickness, enabling the machine to automatically adjust voltage and amperage for optimal performance.

MIG welding comparison other welding processes

Compared to other welding processes, MIG welding stands out for its cost-effectiveness and productivity. The consumables in MIG welding, including wires, are relatively inexpensive. Additionally, the continuous wire feed mechanism enhances productivity, especially when compared to processes like stick welding that require frequent electrode changes.

Frequently Asked Questions

MIG welding is used to join metal parts together. It functions to join steel, stainless steel, cast iron, and aluminum. MIG welding is used on sheet metal, pressure vessels, steel structures, pipelines, and automotive parts.

The MIG welding process has improved upon older welding processes in the speed department, part of the reason it’s now the most popular form of welding out there. The availability of semi-inert gasses like carbon dioxide, which used to be tougher to find, has made its usage with steel products far more common.

Precise: MIG welding offers a high level of precision, able to weld metal that is as thin as 24 gauge, as well as create intricate welding designs. Clean: MIG welding is a clean process with little spatter, allowing for smooth, high quality, slag-free joins requiring minimal clean-up.
