7-3. Troubleshooting
Trouble Remedy
Wire does not feed; open-circuit voltage
available.
Unit overheated. Allow unit to cool.
Check gun trigger plug connection.
Check gun trigger. See gun Owner’s Manual.
Contact nearest Factory Authorized Service Agent.
Wire feeds erratically. Readjust drive roll pressure.
Clean or replace dirty or worn drive roll (see Section 5-6).
Remove weld spatter around nozzle opening.
Replace contact tip or liner. See gun Owner’s Manual.
Change to correct size and type drive roll (see Section 5-6)
Incorrect size or worn wire guides (see Section 5-6)
Check wire drive motor brushes.
Hub tension set too high (see Section 5-11).
Contact nearest Factory Authorized Service Agent.
Motor runs slowly. Check and replace contact tip or liner if necessary.
Hub tension set too high (see Section 5-11).
Contact nearest Factory Authorized Service Agent.
Wire feeds when Jog switch is pressed
but not when gun trigger is pressed. Check gun trigger connection at wire feeder. Check gun trigger leads and trigger switch. See gun Owner’s
Manual.
Contact nearest Factory Authorized Service Agent.
Gas does not flow or does not stop flow-
ing; wire feeds.
Clear blockage in gas hose or replace hose.
Clear blockage in welding gun.
Clear blockage in filter (see Section 7-2).
Check gas valve.
Contact nearest Factory Authorized Service Agent.
Wire remains energized after trigger is
released. Contact nearest Factory Authorized Service Agent.
Gun trigger is pressed, gas does not
flow, wire is not energized, wire feeds. If a welding arc is not established in 3 seconds after the gun trigger is activated, the unit will feed wire
without energizing the contactor or gas valve. The unit will feed approximately 35 feet (10.7 meters) of
wire, then stop feeding. This is to prevent complete despoolling of the wire, as in the case of a damaged
gun.
Display on display board does not light. Contact nearest Factory Authorized Service Agent.
Segments on the display board are
missing.
Replace display board.
Weld voltage on display board is not
accurate.
Weld voltage on the display board will show weld voltage at the feeder. Due to voltage drops in the weld
cables, weld voltage at the feeder will not match weld voltage at the welding power source. Due to aver-
aging of weld voltage, if weld time is less than 8 seconds the displayed weld voltage at the feeder may
not be accurate.
While not welding − Voltage display al-
ternates between three dashes on both
displays.
Contact nearest Factory Authorized Service Agent.
Contact nearest Factory Authorized Service Agent.
While not welding − Voltage display al-
ternates between CC and open circuit
voltage.
Contact nearest Factory Authorized Service Agent.
Weld amperage on display board is not
accurate.
Weld amperage displayed on the feeder will not match exactly with the weld amperage displayed on the
welding power source.
Contact nearest Factory Authorized Service Agent.
Software and weld time information on
display board is not accurate.
