the gas nozzle. Please eliminate it once time after daily use.

9. Strictly prohibit cutting torch head as used as knocking tool

Operatio

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.

Troubleshootin

Notice: Operation below requires operator should have sufficient specialized knowledge about electricity and complete safety 

common sense.

Fault 

Solutio

Switch indicating lamp lights .Fan doesn't control but-

ton is out of control.

It is over-voltage protection. 

Turn off the machine and stop for a while. Then turn on ma-

chine.

Switch indicating lamp lights. Fan runs. 

Press control button of cutting torch, solenoid valve 

in the machine operates, there is no HF arc starting 

discharge sound. And inside shines, indicator lights.

1. IGBT have been damaged (driver module has been damaged)

2. Boost electric transducer of motherboard has been damaged

3. Control module has been damaged.

Switch indicating lamp lights 

Fan nuns. After pressing control button of cutting torch, 

solenoid valve in the machine operates, there 1s no HF 

arc starting discharge sound. And inside shines in red 

color, diode lamp doesn't light.

Arc starting part has problem:

1. The distance of electric discharge nozzle is too far away or 

edge is sticking.

2. Check whether primary coil of arc starting transformer is 

open circuit or bad contact.

3. Check whether voltage rectified diode is breakdown.

4. Check whether HF capacitance 1s electric leakage.

5. Relay is damaged.

All is normal, but it doesn't start arc during cutting.

1. Input voltage is low.

2. Pressure of air compressor is too large or small.
