DUTY CYCLE:
Special note:
If this welders duty cycle is exceeded the welder will enter “thermal overload” which will
automatically stop the welding output in order to protect, both the user and the welder. You will know
the welder has gone into thermal overload when the thermal overload light is illuminated.
The welder will then cool itself down, and once the thermal overload indicator light is no longer
illuminated, welding can then re-commence.
Please note. Exceeding the machine’s duty cycle, cannot be considered grounds for warranty or
return.
The term duty cycle indicates the percentage welding time available at the output current for each 10 min
period over 4 hours,
The specication plate on the machine list three given ratings at a given current and voltage.
NOTE MIG SETTINGS SHOW BELOW : Amps refer to the Current setting
7% 60% 100%
180 - Amps 65-Amps 50-Amps
23.0 Volts 17.3 Volts 16.5 Volts
For example this means when the machine is set at is highest current of 180 Amps it can only weld for 42
seconds in a Ten minute period. The power source is protected by a built in temperature protection device,
This will activate if the machine is operated in excess of its amperage and duty cycle rating.
