JC, i got you!.. The heating tips on a torch are actually welding tips. Used in the old days before electric welding become so popular! I would use a #7 tip to heat the plug of that size.
Also you may not know, Mapp gas is a hotter fuel on the secondary flame. But Acetylene is hotter on the primary side of the flame which is what you use to cut.[/quote]
