1. Make sure there is voltage at the entry to the machine, if
not the tapping must be changed. It is advisable to see if any
magnetothermal has "blown".
The machine has no voltage in one or all its
vital elements.
2. Check the power source fuses situated on the central
panel. (See Spare parts Sheet)
3. The machine panels must be removed testing the logical
points of the electrical diagram.

Magnetothermal switch has low gauge for the
case. There may be a short circuit, which is
what causes the limiter to trip.
Change the magnetothermal for another larger gauge
one. It is important for the magnetothermal switch to have a
characteristic slow type curve. In the event that the electrical
installation has limited power the welding work must be
tested at lower current levels.

Low effective welding voltage. Output wave not
correct.
Check that there is not a phase failure in the supply power.
Check that the electrical contact elements of the welding
circuit are correct: Welding mass, rusty or very dirty surfaces,
contact nozzle with greater diameter than the wire, etc.
Test the electrical diagram of the power source. Input and
output voltages to the rectifier.
The welding wire has a mechanical resistance
at the outlet, which prevents it from having a
regular speed.
Examine the welding gun. Blow the inside (cable) with
compressed air.
