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 are sparks of
HF arc-striking will diminished immediately. User can begin to cut.
INSTRUCTION NOTES
Operation environment
1. The cutting machine can perform in environment where conditions are
particularly harsh and with outside temperature between -10 and +40
degrees centigrade with a dampness level of max 80%.
2. Avoid to use in sun shine 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
electromagneti 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 machin.
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.Voltage automatic compensation circuit will prevent from
exceeding allowable arrange.If power
voltage is too high,that will damaged to components.User must be
carefully.
4. There is a grounding screw which is marked grounding behind cutting
machine. Make sure the mantle is grounded reliably by cable whose
section is 6 square millimeter in order to prevent from leaking electrify and
bringing electrostatic.
