3.2 Cutting Operation instruction
On display
After open the power supply,the power light is light,current meter display the preset current.
Preparation
Input cable connection
Every machine has been disposed a power cable which must be connected to coordinated voltage class in
compliance according to input voltage of cutting machine .If cutting machine whose power voltage is 230V is
connected wrong to AC 400V, that will cause components of inter-machine are burned up.
Make sure power cable is connected to power switch reliably and prevent from oxidizing. Make sure power voltage is
inside the waved range.
Connect Air compressor
Make sure tube of pressed air is connected to copper connector by high-pressure rubber tube firmly.
Connect one end of the trachea to the gas in of the machine and the other end to the air compressor.（Refer to 2.2）
Output cable connection
Earth cable is connected to positive terminal of front panel then tighten it.
Make sure copper screw of another end of torch is connected to gas-electrify integration terminal then tighten them
clockwise relation (prevent from leaking gas). (Refer to 2.3)
Operation
(1) Open the power switch; make the power switch is in “on” position . Screen will show the current volume.
(2) Adjust the gas pressure and make it is adequate to machine, open the valve of pressed air.
(3) Make sure cutting current is adequate to machine according to thickness of cutting piece.
(4) Press the control knob of torch, electromagnetic valve is starting, it can be heard and burner of torch should flow out
gas (Burner of low frequency cutting machines or pilote-arc cutter should spurt fire)
(5) It is 1mm from copper tip to work piece (if it is arc-supporting cutter.),It is 3-5mm from copper tip to work piece (if it is
burner of low frequency cutting machines or pilote-arc cutter ).knob of torch and burn and strike arc,sparks of HF arc
striking will diminished immediately. User can begin to cut.
