Mig Welding Accessory

The Right Tool For The Job.

To improve comfort and minimize
downtime, these conversion kits enable
the use of long lasting Centerfire
Consumables and a wide variety of
interchangeable necks for greater
flexibility and better weld puddle
visibility.

SGA-1 Conversion Kit

SGA conversion kits allow
the use of innovative Bernard
front-end parts for improved

performance and productivity.

Centerfire
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.

CenterfireTM consumables fit most competitive
brand guns to enhance performance and

allow standardization of one contact tip and
nozzle for all gun brands to minimize inventory
management costs.

Necks available in fixed, rotatable, flexible
and multiple length options for optimal weld

accessibility and improved operator comfort.
Rotatable necks changeover without tools.

Patented large tapered Stay-Tite™ neck
connection improves conductivity for better

weld quality, lessens heat to increase operator
comfort.

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.
