Operation Instruction; Questions To Be Run Into During Welding - HBM Machines ARC 200 Handbuch

6. OPERATION INSTRUCTION:

1) Turn the power switch to "ON", the power indicator lit up, cooling fan within the machine start to work
immediately
2) According to the thickness of the welding, the diameter of the electrode, station and technology needs,
ensuring the suitable welding current and thrust current.
3) Clip electrode to the electrode holder, the machine is in the manual welding mode and standby state.
Flat welding using current and electrode specification list:

Specification
Current 70-100A
4) Thrust adjusting knob is used to adjust the welding performance, specially in vertical and overhead
welding. With the use of welding current adjusting knob, it can achieve the ideal effect of welding.
(ARC160 series don't set thrust adjusting knob separately)
5) When using the welder in the location with VRD requirement, please make sure the VRD light is on and
make sure the unload voltage is around 15V with VRD function on
WARNING!
Before conn ecting operation please make sure all the power is turned off. The right order is to
connect the welding cable and ground cable to the machine first, and make sure they are firmly
connected and then put the power plug to the power source.

7. QUESTIONS TO BE RUN INTO DURING WELDING:

1. Environment
1) The machine should be operated in dry environments with humidity level of max 90%.
2) Ambient temperature should be between -10 to 40 degree centigrade.
3) Avoid welding in sunshine or drippings. Do not let water infilter the machine.
4) Avoid welding in dusty area or the environment with corrosive gas.
2. Safety norms
The welding machine is installed with protection circuit of over voltage, over current and over heat. When
voltage, output current and temperature of machine exceed the required standard, welding machine will stop
working automatically. However, overuse (such as over voltage) will still result in damage to the welding
machine. To avoid this, the user must pay attention to the following notes.
