Morning: I am new to TIG .. Are the hookups universal on all makes of TIG torches?I mean the threads where the lines connect to the torch head....My Weldmark has 3 lines, but i would like to try a different brand of torch. I am trying to save the cost of a new 25ft. supply lines.....Thanks Altec
Reply:I would say within the 20 class the threads are the same and within the 18 class the threads are the same. There are a bunch of other numbrs which fit those and some other monsters for industrial use well at last one larger. The 18 and 20 class use the same power block for the electrical and usually discharge water the way I hook mine up.
