PROTECTION FROM OVERHEATING
The duty cycle is the fraction or percentage of a ten-minute cycle that a power source may
be used without overheating. For example, a welding machine with 150 amp - 30% duty
cycle can weld continuously at 150 amps for 3 minutes, and then must cool down during the
remaining 7 minutes to prevent overheating, with the ambient temperature of 40 “C.
Using the machine with the proper duty cycle according to the selected welding current
allows to prevent overheating. If the machine is used for hard work cycle, the thermal
protection device will protect the machine from overheating. In case of overheating of the
machine the “LED TERM” will come on, and the display will show “HOO”. It is possible to start
the welding again once the LED is o and the word “HOO” is no longer on the display.
MAINTENANCE
All maintenance and repairs must be carried out by an authorised repair agent. Any non-
