Bernard Q150X-1 Application guide

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.
OXO® style handle option allows configuration
of Bernard Q-Gun with feel similar to former OXO
APX gun.
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.

OXO® style small curved handle,
medium 45˚ rotating neck.
