Operating Machine
Please ensure all torch consumables are tight before use
1. Ensure machine has been setup as previously stated
2. Turn on the machine and the power light indicates and cooling fan is running
3. Set the function switch in the test gas position, air will flow from torch head, now set the air
pressure in gauge using adjuster on regulator on rear of machine to 50PSI, Once the correct air
pressure has been set press down the adjuster on air regulator and set the function switch to the
cutting position
4. Ensure earth clamp is connected to work piece or workbench ensuring a good clean point of
contact
5. Select cutting amperage knob to desired cutting power (the following guide lines will vary in
accordance to material grade, characteristics and user operation)
a. 20 Amps for up to 6mm clean cut on mild steel
b. 50 Amps for up to 18mm clean cut on mild steel
c. 100 Amps for up to 32mm clean cut on mild steel, when cutting aluminium, alloys and
stainless steel cutting thickness is reduced by approximately 20-25%
6. Hold torch in starting position on work and press torch switch and the high frequency will initiate
the pilot arc and contact with the work piece and machine will automatically switch to main cutting
power. Once you come to the end of cut on work piece the machine will sense this and turn off
main cutting power and pilot arc will re-engage, to stop cutting release switch.
7. Getting correct amperage / cutting speed for desired job.
8. The combination of correct cutting amperage and travel speed can change per user; here are
some tips on obtaining optimum settings.
9. 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
10. Cutting arc is erratic and work is being cut all way through. You are traveling too slow or cutting
with too high amperage for work.
11. 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.

technicians who will be happy to help you.
