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.

3.3 Start Cutting
3.3.1 Edge cutting
Keep the torch vertical at the
edge of the workpiece. Keep
your wrist steady and ready to
start cutting
Pull the trigger to start the arc ,The cutting
arc will initiate when the torch tip is close
enough to the work Piece. Start cutting on
the edge until the Arc has cut completely
through.
fast speed will lead to incomplete cutting,
and arc blowback is easy to damage the
device. Too slow speed will lead to
excessive scum and cutting gap.
