IMPORTANT: MAKE SURE THE POWER SOURCE MEETS THE ABOVE REQUISITES. EXCEEDING THE SPECIFIED VOLTAGES CAN DAMAGE THE
WELDING MACHINE AND INVALIDATE THE WARRANTY.
2.1 - ACCESSORIES
Consult the area agents or the dealer.
2.2 - DUTY CYCLE AND OVERHEATING
Duty cycle is the percentage of 10 minutes at 40 °C ambient temperature
that the unit can weld at its rated output without overheating. If the unit
overheats, the output stops and the over temperature light comes ON. To
correct the situation, wait the unit to cool. Reduce amperage, voltage or duty
cycle before starting to weld again.
