look for the one mentioned on here riverweld or something like that doubleboost gets stuff from him just make sure they are the extended tips
not so sure ask then
Okay,16amp commando plug fitted, DC clamp meter on, adjust potentiometer RP1 - turned anti-clockwise approx 3 turns, 37amps DC delivered. Cuts much cleaner on 8mm mild steel. For reference also attached AC on feed in shows 27.5amp draw.
For Reference:
Dial set to 15amp - shows 15.2 amp DC, draws 11.2amp AC
Dial set to 30amp - before tweak shows 27amp DC actual, draws 18amp AC
Progressive tweaks to RP1:
approx 2 turns anti-clock shows 33amp DC, draws 21.5amp AC.
approx 3 turns anti-clock ( in total) shows 37.2amp DC, draws 27.5amp AC.
Cuts deeper easier, though noticed higher pitched humm from unit when in higher setting.

Did you check to see how making the RP1 adjustment affected the lower settings on the control dial?

A thought - my clamp-on AC meter doesn't read correctly unless I put it around the Live cable only...?
I assumed it was because the transformer in the clamp gets confused by the alternating magnetic field in both the live and the neutral wires, it only shows a sensible reading if I separate L and N and put it around the L only.Why?

( Note, it uses a Hall-effect device to read DC current as well.)
OK, I understand what you were saying now. The effect is not "confusion," it's a cancelling out of the two fields. That said, you can put the clamp meter around either the phase or neutral since the current is the same in both, although they are anti-phase.

Can we have a simple how to for idiots, with pictures?
Make it idiot proof, so I can work on being a better idiot.
