to avoid damage to the torch and machine.

Check the function of all switches.

Check if the fan rotates properly and if there is air
venting out from back of the machine.

Pay Attention to the abnormal vibration, noise,
smell and gas leakage during operation.

Check if the welding cables are over heated.

Check if the cable connections are over heated.

Check if the cable is connected firmly and
properly, if it is broken and cause bad insulation.

Check the cover grounded properly.
screw.

Check the contactors and relays in the machine or
on the PCB work properly.

Calibrate the current meter.

Check the resistance between machine case and
main circuit, if the value is smaller than 1MΩ,
sent the machine to an authorized warranty depot
to inspect and repair immediately.
9. Troubleshooting & Service
The following operations require the operator has sufficient electrical expertise and
comprehensive safety knowledge, the operator can demonstrate its capacity to be held valid
qualifications and knowledge Documents.
Common Faults and exclusion method:
Symptom Solution
Power indicator does not light, fan
does not turn, no welding output.
1. Make sure the power switch is turned on.
2. Confirm that the power input cable is
connected with electricity.
Symptom Solution
Fan switch, or not subject to
potential instability in the welding
current control, current, big,
sometimes small
1. The current potential is damaged, should be
replaced.
2. Bad connections, such as plug-in to be
checked.
Power indicator light shows the
normal fan rotating normal, no
welding output.
1. Check all connectors inside the machine if
there is bad.
2. a circuit output connections or bad.
3. the alarm indicator light
(1)that access to protected status because
of overheating, in which case, To maintain
power, so that the temperature dropped to
the machine fan Reasonable temperature,
until light goes out, you can continue
working;
(2)Check the thermal switch is damaged,
such damage, to be Replacement.
Hot welding clamp
Welding clamp rated current is too small, the
replacement of larger size welding clamp.
Manual welding big splash
Output polarity is unreasonable, reversed output
