touch the weldment. Then press the pedal again the two welding electrode make
contact to weldment when the electrode contact the weldment. It begin to
discharging and welding, Adjust welding current (BI, WI), welding time, welding
electrode pressure to make welding status to achieve optimal welding effect.
Note: To press the pedal switch should be include 2 step:
1.
Lower the electrode to touch the weldment.
2.
Press the pedal to make the electrode contact the weldment.
Don’t let the electrode contact the weldment directly, it will not make welding spark.

To ensure excellent welding quality, frequent maintenance should be conducted
on the welding electrodes. Use small sand paper to make the tips of welding
electrodes even and smooth.

Fuse blown out. Failure in
input power.
1. Replace with fuses of same
specifications.
2. Check power lines.

15A fuse blown
out.
1. Replace with fuses of same
specifications.
3
Power indicator
lights up and
display is good
but no welding
spark.
1. Press the pedal switch
once and make the
electrode contact battery
directly.
2. Parameters for welding
current set too low.
3. Excessive gap
between
lower surface of welding
electrode and batteries.
4. Wires connecting
welding switch broken.
5. Optoelectronic switch
damaged.
6. If working indicator
does not light up or
flicker, it may be caused
by power interference.
1. Press the pedal 2 steps as
5.4 note.
2. Increase welding current.
3. Adjust the gap between
batteries and the surface of
welding electrode to about
3-4mm.
4. Connect wires in compliance
with Fig.1
6. Switch power off and switch
it
on
again.
