• Do not touch electrically live parts
such as output terminals or inter-
nal wiring.
• When inching with gun trigger, electrode and
drive mechanism are “hot” to work and ground
and could remain energized several seconds
after the gun trigger is released.
• Turn OFF input power at welding power source
before installation or changing drive roll and/or
guide tubes.
• Welding power source must be connected to

To verify the wire feed speed,
• Assemble a .045 (1.2 mm) drive roll kit to the feed-
er.
• Remove the gun from the wire drive.
• Load .045 (1.2 mm) steel wire into the feeder. Trim
the wire flush with the front surface of the gun bush-
ing.
• Adjust the wire feed speed to 300 in/min with the
robotic controller.
• Activate and hold the COLD FEED switch for 10
seconds.
• Cut the wire flush with the front surface of the gun
bushing. The wire length should be 50 in/min ± 2.5
in/min.
