OVERLOAD PROTECTION FOR POWER SUPPLY
TO WELDING
Your MIG135 is equipped with a temperature controller as well as an overload breaker. These two protec-
tion devices will protect the welding machine whenever the output exceeds the maximum output. If the
output is exceeded, the unit will not supply voltage and the wire feeder will shut down (the fan will continue
to run to cool the unit).
If the shut-down resulted from output overload, the circuit breaker button will extend out if it has been
tripped. The circuit breaker must be reset manually. Before resetting the circuit breaker button, wait several
minutes to allow the welding machine to cool down.
If there is no voltage and circuit breaker was not tripped, the internal thermal protector may have shut off
the machine until it cools to a reasonable operating temperature. This is an automatic function and does
not require the user to manually reset anything. The fan will continue to run while the unit is cooling.
If the unit is still “ON” but neither the output nor fan is working, either an overload fuse or a power supply
circuit fuse has been blown.
OVERLOAD PROTECTION TO WIRE FEEDER
The MIG135 model has two automatic circuits to protect the motor of the wire feeder. If there is fault to the
motor, the circuit will power off the wire feeder as well as the output.
When the trigger is released again, the circuit will be automatically reset.
