Q-Gun™

Series

200, 300, 400 Amp MIG Guns

USA

Made with

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.

CenterfireTM 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.

Multiple handle and trigger options to increase

operator comfort.

Power cable equipped with Stay-Tite™

Technology and internal gas hose that resists

kinking, improves gas flow and feedability.

Back end with durable rigid strain relief and

easily interchangeable direct plugs and trigger

leads connect to wire feeders and machines

from major manufacturers and allow simple

maintenance.
