4.2 Operation method

1) Turn on the power switch of the machine, and the power indicator illuminates.

2) Select proper working mode and proper function. There are two working modes

available on the machine panel: 2T and 4T.

3) Push the torch trigger on the cutting torch, the cutting machine works.

4) Set cutting current according to the thickness of workpiece.

5) Bring the copper nozzle of the cutting torch into contact with the workpiece (For

models with pilot arc function, keep a distance of about 2mm between the copper

nozzle of the torch and the workpiece.), and then push the torch trigger. After the arc

is ignited and started, raise the cutting torch to the position about 1mm above the

workpiece, and start cutting.

It is recommended not to ignite the arc in the air if not necessary, for it

will shorten the lifespan of the electrode and nozzle of the torch.

It is recommended to initiate the cutting from the edge of workpiece,

unless penetration is needed.

Ensure spatters fly from the bottom of workpiece while cutting. If

spatters fly from the top of workpiece, it indicates that the workpiece

can not be fully cut because the cutting torch is moved too fast or the

cutting current is too low.

Keep the nozzle slightly touching the workpiece or keep a short

distance between the nozzle and workpiece. If the torch is pressed

against the workpiece, the nozzle may stick to the workpiece, and

smooth cutting is unavailable.

For cutting round workpiece or to meet precise cutting requirement,

molding board or other assistant tools are needed.

It is recommended to pull the cutting torch while cutting.

Keep the nozzle of cutting torch upright over the workpiece, and check

if the arc is moving with the cutting line. If the space is not enough,

don't bend the cable too much, step on or press upon the cable to

avoid suffocating of gas flow. The cutting torch may be burned

because the gas flow is too small. Keep the cutting cable away from

edge tools.

Clean up the spatters on the nozzle timely, for it will affect the cooling

effect of the nozzle. Clean up the dust and spatters on the torch head

after using everyday to ensure good cooling effect.
