Pressing the Jog/Purge switch allows the op-

power or gas valve circuit.
•
The unit provides the ability to jog the wire
feeder by means of the gun trigger or the
Jog/Purge switch. If the welding arc does
not initiate in 3 seconds after the gun trigger
is activated, the unit will perform a jog opera-
tion for a maximum of two minutes. If the gun
trigger is still activated after two minutes, the
jog operation is terminated to prevent com-
plete despooling of the wire, in the case of
a damaged gun.
•
The unit displays the “ERR TRIG“ message
to inform the operator that the trigger is acti-
vated.
•
Jog speed can be adjusted by the Adjust
control when the unit is jogging wire. The
unit displays jog speed when the unit is be-
ing jogged.
•
Jogging can also be accomplished by
pressing the Jog/Purge button.
• Pressing the Jog/Purge button also allows
the operator to purge gas lines before weld-
ing and to preset gas pressure at the
regulator.
