inside of the machine should be dried. Then, the insulation of the machine (including between the
connection nodes and between the connection points and the enclosure) shall be measured with a
megohmmeter. Only when it is confirmed that there is no abnormal situation can the welding work be
continued.
10) The welder and welding torch can only be operated according to their duty cycle.
11) The bending radius of the welding torch cable should not be less than 20 cm to avoid fiber breakage.
12) Care for the torch: Rough operation of welding torch is easy to cause wire breakage, water leakage
(gas leakage), and lens damage inside the torch; when not in use, it should be carefully and reliably
placed in the torch holder.
13) Poor flow meter or gas hose connection will lead to gas leakage or reduced gas flow at the front of
the nozzle, so the gas protection effect will be reduced, and the weld gas pores are prone to appear.
14) There should be windproof measures in windy workplaces, otherwise, it will blow away the protective
gas and form gas pores.
15) Clean the oil, rust, paint, water and other conductive substances attaching on the base metal surface
to be welded; otherwise, it will become pores and cracks, and can not obtain good welding effect.
16) During manual wire feeding and inching, do not direct the guide wire nozzle to people or equipment
to avoid puncture.
17) Do not replace the wire feed roller when the wire feeder is powered on to avoid being crushed.
Warning! The machine is equipped with an abnormal temperature protection
circuit. When the water temperature is too high/low, the machine will trigger an
alarm and automatically stop the light emission.
