5-10. Jog/Purge
Pressing the Jog/Purge switch allows the
operator 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 seconds after the gun trigger
is activated, the unit will perform a jog
operation for a maximum of 30 seconds. If
the gun trigger is still activated after 30
seconds, the jog operation is terminated to
prevent complete unspooling of the wire, in
the case of a damaged gun. The unit
displays the “ERR STRT“ message to
inform the operator that the trigger is
activated.
•
Jog speed can be adjusted by the Adjust
control when the unit is jogging wire. The
unit displays jog speed when the unit is
being 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
welding and to preset gas pressure at the
regulator.
•
This unit is equipped with Auto Thread
capability. By rocking the switch from purge
to jog within 0.5 seconds will automatically
feed wire for a factory default setting of 192
in (4877 mm) of wire before stopping. The
default feed rate is 700 ipm. These settings
can be changed using an optional PDA with
File Management software. Pressing the
Jog/Purge switch or gun trigger during Auto
Threading will terminate the automatic feed
operation.
