6. Press the welding
torch
switch,
welding can be
carried out, but the
voltage can not be
adjusted.
1. Check if the voltage feedback cable inside the machine is ok.
2. The control PCB PK-63-A2 inside the machine fails.
7. Welding current is
unstable.
1. Check the pressure of the wire feeder pole is appropriate.
2. Check if the wire feed wheel matches the welding wire.
3. Check if the contact tip is badly abraded. If it is, replace it and
tighten it.
4. Check the quality of the welding wire.
5. Check if the welding torch cable is too winding.
6. Check if the metal connection part of the fast plug is loose.
8. The weld bead is
not well protected.
1. Do not remove the welding torch as soon as the welding stops.
Thus the shielded gas can protect the hot weld bead.
2. Prolong the post-flow time, or contact our company.
Note: This machine is in continuous improvement, so other parts may be different
except the function and operation. Your understanding would be greatly appreciated.
