Hypertherm Max-20

Yes, bike passed

When machine is switched on and air connected you should have 2 green lamps (power & temp/pressure) if not, try the following (remembering you are working on live/high voltage equipment)

Meter set to AC >24V connect one lead to point 16 on drawing, other lead to 17 (checks voltage) then follow through 3A fuse - point 13 , 12, grey wire to 1TAS, grey to 2TAS, then yellow, if all OK you should have power to point 21 (violet wire to trigger). Operate trigger puts power to point 20 (another violet) then to points 6 (gas solenoid) & 8 (1CR & 2CR)

See what you can find?

do you mean >240V?

No, it's measuring 24V AC control voltage from transformer
