I have been searching for se kind of adapter fitting,but I am not having much luck.does any body have any suggestions or expierience with trying to c...

Ok thanks that sounds like the info I was looking for

I have a praxon torch, I think that is how it is spelled, buy I'm not sure what type of gas lenses they ware, I bought them off of eBay. It said they would fit a 20 style torch but they do look quite a bit bigger in diameter

i have a 20 torch and want to get gas lenses for it and i am not sure if i need a different white insulator to accomadate the bigger gas lense collet body and cup.

Thanks for the information

thanks for the info on the cup length and heat issue. the water tank i have was home made and i dont think the pump is pumping enough volume .im going to have to look into the water circulation info

Are there any advantages / disadvantages to haveing a LONGER gas cup. I've seen longer ones all over the internet but they could just be from a diff manufacturer. Mine is water cooled but my torch has been getting pretty warm when I weld for a little while.
