MIG welding (GMAW – Gas Metal Arc Welding) is the most common process used in home shops, small businesses, manufacturing and metal fabrication applications. Choose from single-phase MIG welding machines or more powerful three-phase MIG welding systems that suit an endless variety of applications, including stainless steel and aluminum welding.
TIG (tungsten inert gas) welding is used to make precise, critical welds when joining metals such as mild steel, aluminum, or stainless steel. TIG welding is a two-handed process (one hand holds the torch while the other feeds filler metal) and commonly involves a foot pedal or fingertip remote to control the arc voltage while welding. Like MIG welding, a shielding gas (typically argon) is required.
MMA welding is a simple yet universal, inexpensive and portable welding process. Flux coated welding rods are used, eliminating the need for bottled shielding gas like that used in MIG welding or TIG welding. Stick welders are ideal to use when welding outdoors and/or welding objects that are rusty or dirty. Most common metals and alloys can be joined using a stick welder. Choose from a variety of i-WELD stick welders, including some that also offer TIG welding capabilities for more universality. Product comparison is available on product pages.
Plasma cutting is used in cutting and gouging applications and requires compressed air and electricity to create plasma gas. i-WELD plasma cutters can cut up to 7/8-inch steel and stainless steel material, and up to 5/8-inch aluminum material.
