Output Overload
The WELDMARK 135 PLUS is equipped with a circuit
breaker which protects the machine from potential
damage from excessive output current. The circuit
breaker button will extend out when tripped. The cir-
cuit breaker must be manually reset.
Thermal Protection
The WELDMARK 135 PLUS duty cycle is exceeded a
thermostat will shut off the output until the machine
cools to a normal operating temperature. This is an
automatic function and is self resetting.
Wire Feed Overload Protection
If the WELDMARK 135 PLUS has an automatic elec-
tronic protection circuit to protect the wire feed motor.
If excessive motor overload occurs (due to excessive
feeding force, jammed drive rolls, or shorted motor
leads) the circuit will shut down the wire feed motor
and the welding power output.
The wire feed shut-down circuit will reset automatically
when the gun trigger is released. However shut-down
will reoccur if the overload situation is not corrected.
