Model "T" coil?

The HF units are based on the tesla coils. This is a coupling coil that allows the HF to couple with hot lead of the welder but it is not directly connected, I guess by induction. The Sears unit is using 3500 volts and the amperage is measured in milliamps. You could make a coupling coil or buy one from a welding supply co? car coil might be a slight hazard as ignition coils are high tension. Might get bit (shocked) allot more than you would like to. The HF unit I have is a very low amperage, you can barely feel it sometimes and that is if you put your finger directly in the arc of only the HF unit with out the welder turned on. This unit will jump about 1/4" to 3/8". Hey man, If you try it with coil and it works, let us all know!! It would be a cheap way to go and there could be thousands of old welders turned into TIG units for little cash. Good luck, I hope you experiment with it and get it working
