Jog/Purge Switch
Pressing the Jog/Purge switch allows the op-
erator to jog wire without energizing the weld
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 sec-
onds after the gun trigger is activated, the
unit will perform a jog operation for a maxi-
mum of two minutes. If the gun trigger is still
activated after two minutes, the jog opera-
tion is terminated to prevent complete des-
pooling of the wire, in the case of a damaged
gun.
•
The unit displays the “TRIG ERR“ 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.
