Can somebody point me in the right direction for a large gas lens setup for welding stainless pipe? I have an HTP 221 and I bought their gas lens set, but the largest is an 8 and I'm still not getting the results that I want. I wasn't sure what other brands were compatible.

 

Depends on your torch type....but this is the best money can buy.

Go to www.arc-zone.com and get the part numbers for what you need.

Then go to www.weldingcity.com and order the pieces. They have better prices and you don't have to buy as large a quantity at a time as you do on Arc Zone.
