X8 MIG WELDER 2.6 Troubleshooting
Problem Recommended actions
The wire burns into the contact tip
• Make sure the size and type of the current tip and
wire liner are suitable for the filler wire.
• Make sure the wire liner is clean.
• Make sure the wire liner does not make any steep
loops.
• Check the motor current level. If the current is too
high, there may be problems in the wire liner.
• Check the tightness of the feeding rolls. Too tight
feeding rolls may affect soft filler wires, such as
aluminium and flux-cored wires.
The gun overheats
• Make sure the coolant circulation is working
normally (see the coolant circulation warning LED
in the power source).
• Measure the coolant circulation speed: detach the
coolant output hose from the wire feeder while the
power source is on, and let the coolant run into a
measurement cup. The circulation must be at least
0.5 l/min.
• Make sure that the welding parameters are within
the range of the welding gun and the neck.
The gun and the neck have separate limits for
the maximum current; the lower of these is the
maximum current that can be used.
The welding gun connector
overheats
• Make sure the connector is properly connected to
the wire feeder.
• Make sure the current transfer surface and the
connector pins of the gun connector are clean and
undamaged.
The gun vibrates too much during
welding
• Check the tightness of the contact tip adapter and
contact tip.
• Check the motor current.
• Check the wire liner.
• Check the filler wire. It must be straight and start
coiling when it comes out from the contact tip. If
not, check the tightness of the feeding rolls.
