50Hz/60Hz fre- quency is inverted to high frequency (frequency is over 100KHz) by 1GBT, then step down voltage and rectification current, inverter power supply generates powerful DC welding cur- rent through PWM technical. Because inverter technical of switch power is used, dimen- sions and weight of main transformer has reduced substantially and efficiency has in- creased 30%. Piloting arc system can strike arc easily with principle of high frequency oscillating.
It has functions that it can supply gas ahead and turn off gas delayed. Cutting smoothly and no polish demands.
Cutting machine can be used widely:it is suitable for cutting stainless steel, alloy steel, mild steel, copper and other color metal materials. Make sure the machine on/off switch is in the off position.Plug the power cord plug into the outlet. Connect air compressor with air regulator/filter. Connect the ground clamp to your work piece.
Caution: Rust or paint on the work piece could create an open circuit; therefore, the contact point should be cleaned thoroughly to ensure a good connection between clamp and work piece. Turn on the power switch. The cooling fan should start to operate and the LED should come on.
The front panel should show the machine's electrical current volume, and you can adjust it by turning the nob below the display. Adjust the air pressure on your air compressor to 60 - 65 psi for the machine. Bring the torch tip into direct contact with your work piece edge or, for thicker cutting, over a pre-drilled pilot hole. Press the button on the torch to start cutting.
Ensure that the cutting current is appropriate and adequate for the machine based on the rated thickness of the cutter. 1X Barometer (attached to the machine).
