MIG Welders (GMAW)

MIG welding is a simple process of welding metal together. Welding Wire is fed through the MIG Gun at a controllable rate to fill in the desired weld. LONGEVITY offers a variety of quality MIG welding machines that are affordable, powerful, and universal in terms of power requirements. With the LONGEVITY MIGWELD series, you will be able to weld like a professional on all exotic metals including aluminum with the optional MIG Spool Gun. Check out our welding videos and models. If you have any questions, we are always here to answer them!

Why choose a MIG welder over other welding methods?

MIG welding is considered to be the simplest way of welding two pieces of metal together because welding wire is fed through the gun similar to the action of a glue gun. That is why MIG welding is often referred to as a metal glue gun. Wire is fed by the wire feeder through the torch and the wire melts creating a filler puddle of melted metal on your workpiece. MIG welding is a more simple process than TIG and STICK because with TIG welding, timing and manually feeding the filler rod requires more precision. With stick welding, you have a combustible electrode that requires you to maintain the proper height while moving to continue the arc. With the MIG process, its simply move and hold the trigger while trying various methods available for proper distribution of welding wire.
