Dave, link is missing 404 on above.
I'll be taking in a 330 C25 tank this week for swap, I attached the 25AK nozzle (spare I have had for a couple years). I'll see what tweco or other brand will work from LWS. This one I picked up from Everlastwelders.ca (Jean) a couple years ago. She sent two, still on the first oneAnti-spatter spray is key.
