Check condition of main power line (unit connection,
fuses, main circuit-breaker, etc.). If no power supply prob-
lems, call an authorized Chief representative.
Inadequate electrical supply, too low initial voltage or
important drop of voltage during weld results in high sup-
ply amperage. Have installation checked (initial voltage,
length, size of wire, tightening of connections , etc.).
Check condition of main power line (unit connection,
fuses, main circuit-breaker, etc.).
Same as above. Change breaker to higher amperage type
if necessary. (60 amps - slow action type.)
Wait until machine finishes auto test.
Machine is OK ready to work in few seconds.
