I think that maybe a WP 9 with with a Gas /Power Cable would be ok.You are going to hate me for my next statement,a torch switch taped to the handle has proven to be ok.Just looked at your post,looks like a WP17v with a standard ceramic etc.How did you find the seperate Gas/Power Cable?The torch head looks like a standard Silicon type head,maybe CK or Weldcraft.As you say they were a good torch,the good news is that Esab still supply them in their TIG packages.
