The static external characteristic of this machine is dropping characteristic, it`s rated duty cycle is 35%, which
means in a 10 minutes work cycle, the welding machine can work 3.5 minutes(stop 6.5 minutes) under the rated
current. If it is forced to use over the rated duty cycle, the inner temperature will exceed the set temperature. To avoid
poor working or burning, a overheating protection function is set: when overheating, the indicator light lights and
there is no out-putting from the welding machine, it can work again after the temperature dropping.
When welding current is lower than 200A, the gas flow is 8-15L/min, when the welding current is larger than 200A,
the gas flow is 15-25L/min.
