7. During cutting, keep cable straight as much as possible. If space is not permitted, don't bend cable strongly. In the
meanwhile, don't trample on foot or press cable in case of blockage of air current or small current to bum and damage
cutting torch. Cutting cable should be avoided touching edge tool in case breakage to affect normal use.
8. Unload nozzle cap, nozzle, remove the torch from the machine. This will avoid burn and damage cutting torch. After
turning on machine, press switch button, at this time, there is gas come out of gas nozzle. Doing this step is to test if stuff
blocked in the gas nozzle. Please eliminate it once time after daily use.
9. Strictly prohibit cutting torch head as used as knocking tool

Operation

1) Turn on power switch at the back panel to make power switch at position of "ON" At this time, power switch indicating
lamp lights and screen of gauge outfit displays set current value.
2) Adjust pressure regulating knob of air reducing valve to pressure that needs T. on valve of compressor air appropriate air
pressure will reduce loss of nozzle and electrode, and improve cutting power.
3) Press control button of cutting torch, solenoid valve operates, you can hear electric discharge sound of HF arc starting, in
the meanwhile nozzle of cutting torch has gas out (nozzle of cutting torch of the cutter with keep alive has plasma ejects).
(4) Please set corresponding cutting current according to thickness of cutting work-piece.
(5) Make brass mouthpiece of cutting torch contact with work-piece. After pressing button of cutting torch to ignite arc
starting, appropriately lift cutting to arch to make it 1mm away from work-piece, and you can start to cut.
Maintenance
1) Regularly dust: Please dust with dry clean compressor air. If you use the cutter in the environment within which smoke is
large, air pollution is serious, user should clean dust at least2 times each month.
2) Compressor air should lower to pressure that required (normally 1s 3-4 pressure) in case damaging small elements in the
cutter.
3) Check whether electricity joint inside the machine is good contact (especially connector). Please reinforce loose contact. If
it has oxidation, user should eliminate oxide stuff with sand paper and reconnect it.
4) Avoid cutter from entering into water and wetting or dry it in time. Please measure insulation condition (including
between tie point and tie point, between lie point and chassis). You can just continue cutting operation on condition that
there is no abnormal case.
5) If use for long time, user should put cutter into original packing and keep it in a dry environment.
