OVERLOAD PROTECTION

Output Overload

The SP-135 PLUS is equipped with a circuit breaker which protects the machine from potential damage from excessive output current. The circuit breaker but- ton will extend out when tripped. The circuit breaker must be manually reset.

Thermal Protection

The SP-135 PLUS duty cycle is exceeded a thermo- stat 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 SP-135 PLUS has an automatic electronic pro- tection circuit to protect the wire feed motor. If exces- sive 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.
