Pride and without
Compromise in the
All Guns are Not Created Equal.
A MIG gun should be durable, easy to
use and customized to your specific
application. Our MIG guns put you in
control: you choose the options you need
and we'll build a gun to last. We even
ship most of our guns within 24 hours.
Centerfire™ contact tips, nozzles and diffusers
are easy-to-use and high performing - they
provide better arc starts, less spatter and more
consistent welds - and also last up to three times
longer than competitive brands.
Necks available in fixed, rotatable and multiple
length options for optimal weld accessibility and
improved operator comfort. Rotatable necks
changeover without tools.
Patented Jump Liner allows quick neck change
and replacement of only most commonly worn or
clogged liner area, which reduces the amount of
time a gun is offline and minimizes inventory.
Liners coiled in-house with proprietary process
that improves wire feed performance and 100
percent tested to ensure smoothest wire feed in
the industry.
