Powermax 45xp lost arc delay (Solved)

Note that a normal external SSR block type relay's would not be expected to work well
as these often need a minimum current and have significant voltage drop because they use
bipolar transistors and must get their base drive from the switched power side

A MOSFET type SSR would be superior to a mechanical relay

This has gotten so much out of hand that i need to source a 7i96 as soon as possible to test this.
I would venture a guess that all the issues stem from the interference caused by the high voltage torch start.
The smallest SSR i have are 12A AC ones so not really useful for this.

FWIW I use a 7i96 to directly switch the torch on my Powermax30 without any issues. Although that is obviously not a CNC ready machine.

Where do you call home? Odds are really low you are near me, but if so you could use mine for some testing. I'm in Utah USA.

Haha, well that is pretty close. :laugh: :laugh:
