YF-22 A2
5. It is 1mm from copper tip to work piece (it is further if it is arc-supporting cutter.),
press knob of torch and burn and strike arc, sparks of HF arc striking will
diminished immediately. User can begin to cut.
INSTRUCTION NOTES
Operation environment
1. The cutting machine cam performs in environment where conditions are particularly
harsh and with outside temperature between ā10 and +40 degrees centigrade with a
dampness level of max 80%.
2. Avoid using in sunshine and dropping environment.
3. Keep machine dry and avoid water into machine.
4. Do not use the cutting machine in environment where condition is polluted with
high concentration of dust or corrosive gas in the air.
SAFTY
1. Make sure the working area is adequately ventilated.
Cutting machine is light and its structure is compact and the electromagnetic fields
generated the high current .So natural wind is not satisfy to cool down components,
there are two axial-flow fan in inter-machine in order to force to cool down it.
NOTES: Exhaust shutter must not in block or covered, it is 0.3 m from machine to
environment objects. Make sure keep improving ventilated situation, it is very
important to machine.
2. No over-load!
Limited to cutting current strictly according to max allowable current with all kinds
of duty cycles.
Do not exceed load working in order to prevent from shorting use lifetime of
cutting machine even burning up machine.
3. No over-voltage!
Power voltage range of cutting machine is according to main technical data sheet.
