The XR-Aluma-Pro air-cooled gun offers 300 amps—

more amperage than the competition can handle.

Aluminum-series-specific tension settings ensure smooth wire

feeding performance with 4000 or 5000 series aluminum wires.

At 900 inches per minute, this gun will feed wire faster than any

of its predecessors. (Dependent on feeder used.)

3-3/4 turn potentiometer provides better resolution when selecting

the right wire speed for the job. The recessed WFS (wire feed speed)

control offers durability yet is easy to use while wearing welding gloves.

Replaceable feed cable liner is designed to provide

consistent arc performance. It also reduces parts cost

and service time by allowing a simple means of removing

and replacing liner and not the complete feed cable.

Serviceability. This gun features a full-length Velcro

seamed leather jacket with integrated strain reliefs for

easy cable maintenance and protection. The gun also

features quick connectors between the control cable and

electrical components (trigger, motor, potentiometer).

Isolated, common, knurled drive roll helps reduce

wear, reducing downtime and cost. Gun feeds

.030 –3/64 inch right out of the box without

need for separate drive rolls. Kit #230 708 is

required to run 1/16-inch (1.6 mm) wire.

Easy access to drive assembly and

removable head tube reduces service

time. Pressure release lever allows

drive rolls to be held open for

wire changeover.

Guns are warranted for 1 year, parts and labor.
