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 50 ipm rate for
3 seconds, then the rate ramps up to 700
ipm until the Jog switch is released.
. “ERR STRT” will occur after the first 3
seconds of run in without starting an arc
preventing wire jog when using the gun
trigger. To use the gun trigger to jog wire,
the Start Error time must be increased
using an optional PDA with File
Management software.
• 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
present as indicated on feeder upper
display. After 3 seconds the weld output
turns off and the wire will feed at 50 ipm for
the next 3 seconds and then ramps up to
700 ipm until trigger 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.
• 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 software.
