Duty cycle and Overheating

The duty cycle of a welding machine is the percentage of

time in a 10 minute cycle at which the welder can operate

the machine at rated welding current.

Example: 60% duty cycle:

Welding for 6 minutes. Break for 4 minutes.

Excessive extension of the duty cycle will cause the

thermal protection circuit to activate.

The machine is protected from overheating by a

thermostat. When the machine is overheated the output

of the machine will turn "OFF", and the Thermal Indicator

Light (on front panel of wire feeder) will turn "ON". When

the machine has cooled to a safe temperature the

Thermal Indicator light will go out and the machine may

resume normal operation. Note: For safety reasons the

machine will not come out of thermal shutdown if the

trigger on the welding gun has not been released.
