4. “arc-leading pulse knob” is to adjust the welding function, esp. match “current knob”
in little current range, can take convenience to adjust the current of arc-starting, and
is out of control of the “welding current knob”.
3-2. Allowed duty cycle
Strictly work in conformity with the required duty cycle. (see the technical parameter) if
work under over duty cycle, the machine may suddenly stop working. That’s the inner
thermal parts work because of over-loading. Under this circumstance.
Cautions!
4-1. Working environment
Under comparative dry environment, the moisture 80%; the environment temperature
should be between -1OC and +40C; avoid working in the sun or rain; avoid working in
the environment where there is much dúst or corrosive gas.
4-2. Safety tips
1. Good Ventilation
This machine is little in volume , tight in structure, and big in current output, so the natu
-
ral air circulation can not satisfy its need, and we add special fans in it for cooling.
Re: Cautions: make sure the two terminals and shutter of the cutter are not blocked
and covered, and the machine should be placed 0.3m away from the surroundings;
please always im prove the Ventilation, because it’s very important for the normál
working of the welding machine.
2. No over-load working
Over-loading is forbidden or the cutter may stop suddenly during the cutting course.
That’s, the inner thermal parts works under over-load condition. Under this circum
-
stance, no need to cut off the power switch, leave the fan whirl to speed up the tem
-
perature lowering. If the temperature drops to the given range, the work will recover.
3. No over-voltage
The power voltage range of the machine see the “Main parameter” table, under this
circumstance, the inner voltage will complement all by itself, and guarantee the weld
-
ing current not surpass the allowed value. Please be more careful if the parts are dam
-
aged because of over-voltage.
4. Each machine has a screw for earth connecting, the mark is earth signal, please
choose a 10mm cable to connect the case of the machine to earth to avoid break
-
down caused by static electricity or electricity-leaking.
Do not touch the output terminal when working, or it may cause electric shock.
