Finally got around to trying the tig on my 250 EX today and after fixing the gas line that was plumbed wrong on the torch only to discover I have no HF start. I tried 2T and 4T mode and switched from peddle to torch with no change. I can scratch start and the lift arc works but with HF there is nothing, not even a buzz. I will call Mike tomorrow. On the gas like: The water flows into the line that attaches to the power line? This was the line that had the quick fitting on it but the gas just went out the other hose like the coolant would flow to cool the torch. I checked the flow of each line and connected the one that passed through the torch.
On a side note; the SuperCut 50 you need to include spacers and longer screws so you can attach the regulator to the unit. Otherwise the regulator will not fit in the supplied bracket.
