4. OPERATION
4.1. DUTY CYCLE AND OVER HEAT / THERMAL PROTECTION
Duty cycle is dened 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 overheats, the IGBT overheating protection unit inside the appliance will instruct the appliance to cut the
output welding current, and will light the overheat pilot lamp on the front panel. At this time, the machine should be rested for 15
minutes to allow to cool. When restarting the machine, the welding output current or the duty cycle should be reduced.
4.2. MOVEMENT AND PLACEMENT
Please take care of the welder when moving it, and do not carry on its side. It can also be moved by the handle on the top of the
welder. Place the welder well when moving it to the right position. The 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.
4.3. POWER SUPPLY INPUT CONNECTION
The TIGACDC200 welding machine power supply connects to 230V. When the power supply voltage is over the safe work voltage,
there are over voltage and under voltage protection inside the welder, the alarm light will come on, at the same time, the current output
will be cut o. If the power supply voltage continually goes beyond the safe work voltage range, it will shorten the welder life-span. The
below measures can be used:
4.3.1. Change the power supply input. Such as, connect the welder with the stable power supply voltage or distribution.
4.3.2. Reduce the machines using the same power supply at the same time;
4.3.3. Set the voltage stabilisation device in the front of power cable input (see control panel 4.7).
4.4. ENVIRONMENT
4.4.1. Height above sea level is below 1000m.
4.4.2. Operation temperature range:-10 to 40.
4.4.3. Relative humidity is below 90 % (200C).
