The Jog/Purge switch provides the following
functions:
• Pressing left side of the Jog/Purge switch
allows the operator to feed wire without
energizing the weld power or gas valve
circuit. The wire will feed at a 60 ipm rate for
3 seconds, then the rate ramps up to 700
ipm until the Jog switch is released.
• The unit also provides the ability to jog the
wire feeder by means of the gun trigger.
When the gun trigger is pressed without
starting an arc, the wire will feed at run-in
speed for the first 3 seconds. During this
time OCV (open circuit voltage) will be pres-
ent as indicated on feeder upper display. Af-
ter 3 seconds the weld output turns off and
the wire will feed at 60 ipm for the next 3 sec-
onds and then ramps up to 700 ipm until trig-
ger is released or 30 seconds elapses. If the
gun trigger is still activated after 30
seconds, the jog operation is terminated to
prevent complete unspooling of the wire and
an “ERR STRT” message is displayed on
the upper and lower displays. Releasing
and pressing the trigger again will clear the
error.
.
If Start Error is enabled using an optional
PDA with File Management/WaveWriter
software, an “ERR STRT” will occur after
the first 3 seconds of run in and jogging
from the trigger is not possible.
• Pressing right side of the Jog/Purge switch
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/WaveWriter software.
