Re: PCD tools

This is the only link I have used and it gives a general overview, if I will look out for more and add it.  Can you give any details of the application.

... A free-running HF arc starter is the conventional brute force approach. More recent designs use a single HV like-polarity pulse at the start of an AC cycle

Thanks for that, Jong. I don't know if I'll build one, but I'll sure keep my eyes open for old microwaves just in case I ever do need a spotwelder. I'll have

Re: ]Re: [Welding_Projects] Re: debugging diy tig inverter

Yup. That's exactly it, expect for AC, V = X*I, where X is the capacitive reactance. In this case 0.318 Ohms. I don't think the HF current is that high either.

Recently saw a flat-top IdealArc 250 on CL for 450 dollars, then it dropped to 300 so I bought it. 50 mile drive one way with my low trailer. Bought it out of

From what I understand, since the current across the capacitor will not be very high the voltage across it won't be very either since V = R * I. If the HF
