3.2 Duty cycle & Over heat
Duty cycle, which is defined as the proportion of the time that a machine can work continuously
within a certain time (10 minutes). The rated duty cycle means the proportion of the time that a
machine can work continuously within 10 minutes when it outputs the rated welding current.
If the welder is over-heat, the IGBT over-heat protection unit inside it will output an instruction to cut
output welding current and brighten the over-heat pilot lamp on the front panel. At this time, the
machine should be relaxed for 15 minutes to cool the fan. When operating the machine again, the
welding output current or the duty cycle should be reduced.
3.3 Movement and placement
Please take care when moving the welder when moving it, and do not sit it on uneven ground.
It also can be moved by the handle on the top of the welder. Place the welder carefully when moving
it to the right position. When the machine gets to the destination, it needs to be secured to prevent
movement.
Movement may result in the potential danger or substantive hazard, so please make sure that the
machine is in a safe position before using it.
3.4 Power supply input connection
ArcoTig HF200P welding machines’ power supply connects to110V/220V.
When the power supply voltage is over the safe work voltage, there are over voltage and under
voltage protections inside the welder, the alarm will light up and at the same time the current output
will be cut off.
If the power supply voltage continually goes beyond the safe work voltage range, it will shorten the
welders life-span. The below measures can be used:

Change the power supply input net. Such as connect the welder with the stable power supply
voltage of distributor;

Reduce the machines work load and ensure input supply is regular.

Set the voltage stabilization device in the front of power cable input.
