Hi Guys,

I'm running a powermax 45 on a custom built table using candcnc dthc2 electronics, mach3 software. I'm having an intermittent problem with loosing the arc sometimes whilst cutting. Here's what happens: I can be cutting some parts fine and then when cutting 1 part the torch will loose arc whilst still in motion, re-fire and complete the cut. This is obviously highly annoying as it messes up the part. I tend to find that the thicker the material or the longer the cut the more likely I am to experience this problem... I'm wondering if this is an air issue?? I'm just using a crappy inline moisture filter until I get my drier plumbed in. Is this likely to be the cause, or is there something else I should be looking for?

Thanks
