Troubleshooting (continued)
iMportant!
Be cErtain to shut off the Welder, disconnect it from power, and discharge the Mig gun to
ground before adjusting, cleaning, or repairing the unit.
problem
possible causes
likely Solutions
Welding arc
not stable
1. Wire not feeding properly.
2. Incorrect Contact Tip or liner
size or excessive wear.
3. Incorrect wire feed speed.
4. Loose MIG Gun cable or ground cable.
5. Damaged MIG Gun or loose
connection within Gun.
6. Incorrect polarity for process being run.
7. Gas coverage may be insufficient or too high.
8. Poor connection with workpiece.
1. See first Troubleshooting section above.
2. Replace with the proper tip or liner size for wire used.
3. Adjust wire feed speed to achieve a more stable arc.
4. Check to ensure that all connections are tight.
5. Have a qualified technician inspect
and repair/replace as necessary.
6. Ensure polarity is correct for operation: DCEP
for MIG and DCEN for Flux-Cored.
7. Ensure gas flow rate is set according to Settings Chart.
Make sure MIG Gun Cable Connector is fully inserted
into Wire Feed mechanism with no O-Rings exposed.
8. Check the ground clamp connection
to the workpiece and machine.
Ensure the MIG Gun is properly secured.
Weak arc strength
1. Incorrect line voltage.
2. Improper gauge or length of cord.
3. Not enough current.
1. Check the line voltage and, if insufficient, have
a licensed electrician remedy the situation.
2. Do not use an extension cord on this Welder.
Use only one of the supplied power cords for
this Welder or an identical replacement cord.
3. Switch current to proper setting for metal thickness.
When switched on,
Power Indicator
lights but Welder
does not function
1. Tripped thermal protection device.
2. Faulty or improperly connected Trigger.
3. Machine is in low- or
over-voltage protection.
4. Machine is in the incorrect mode.
1. If the Alarm Indicator is illuminated without an error
code, Welder has overheated and shut down. Stop
and wait with the Power Switch ON for the Welder
to cool. The Welder automatically returns to service
after cooling off. Reduce duration or frequency of
welding periods to help reduce wear on the Welder.
Refer to Duty Cycle (Duration of Use) on page 18.
2. Ensure the gun connection is properly
seated on machine. Qualified technician
must check and secure/replace Trigger.
3. If the Alarm Light is illuminated, check input voltage
and ensure it falls within the specified range. If input
voltage is correct, turn Welder off and back on.
4. Ensure the MIG Flux/Spool Gun switch located above
the Wire Feed mechanism is switched to the correct
process. Refer to Interior Controls on page 9.
Power ON Indicator
does not light when
switched on
1. Unit is not connected to outlet properly.
2. Outlet is unpowered.
3. Circuit supplies insufficient input voltage or
amperage.
4. Plug does not have correct rating.
5. Input Power Cord is not seated properly.
1. Verify the voltage at the outlet and
the connection to the outlet.
2. Check circuit breaker/GFCI devices;
if any are tripped, determine and
remedy cause before resetting.
3. Verify that the circuit is designed to supply the
required input voltage and amperage as detailed on
the Specifications table. If the Voltage Input/Thermal
Overload Indicator is illuminated on machine, check
the input voltage to ensure it is within specified range.
4. Make sure installed plug is correct rating.
See Specifications on page 7.
5. Ensure the input Power Cord is fully secured.
Follow all safety precautions whenever diagnosing or servicing the equipment.
