Please ensure all torch consumables are tight before use
1. Ensure machine has been setup as previously stated
2. Turn on the machine, the power light will light up and cooling fan starts running
3. Press torch switch, air will flow from torch head, now set the air pressure in gauge using
adjuster on regulator on machine to 70PSI
Once the correct air pressure has been set press down the adjuster on air regulator.
4. Ensure earth clamp is connected to workpiece or workbench ensuring a good clean point of
contact
5. Select cutting amperage knob to desired cutting power (the following guidelines will vary in
accordance with material grade, characteristics and user operation)
20 Amps for up to 6mm clean cut on mild steel
30 Amps for up to 8mm clean cut on mild steel
When cutting aluminium, alloys and stainless-steel cutting thickness is reduced by approximately
20%
6. Hold torch in starting position on work and press torch switch and the high frequency will initiate
contact with the workpiece and machine will automatically switch to main cutting power.
Once you come to the end of cut/workpiece the machine will sense this and turn off main cutting
power, to start cutting again, release switch and press again.
7. Getting correct amperage / cutting speed for desired job.
The combination of correct cutting amperage and travel speed can change per user, here are
some tips on obtaining optimum settings.
Blow back when cutting – If you experience blow back and the metal is not cut all the way
through, you either are traveling too fast or you need to increase the cutting amperage
Cutting arc is erratic and work is being cut all way through. You are traveling too slow/fast or
cutting with too high/low amperage for work.
It can take a while to get used to plasma cutting if never done before. Experiment with settings on
some scrap material until you find the best amperage / cutting speed for user.
If you ever have any questions on settings call us and speak to one of our experienced
technicians who will be happy to help you.
