TIG WELDING STAINLESS .063" WALL SANITARY TUBE WITH SCRATCH START RIG

TIG welding sanitary stainless with primeweld TIG225

TIG welding sanitary stainless tubing is all about the purge and the inside of the tube. Of course you want the outside of the weld to look good too but the quality of the purge and smoothness of the root is the main desired outcome.

In my opinion, the primeweld 225 is one of the best choices in affordable tig welders.

The problem with most other really affordable tig welders is usually a really cheap foot pedal and TIG torch.  Primeweld went to extra expense to include a genuine CK17 torch with superflex hose along with a very smooth SSC style foot pedal. 

A high quality CK dinse adapter is also included so that you can easily swap out a tig torch or cable when the time comes. 

Primeweld also has a responsive primeweld equipment users group on facebook and also has demonstrated great customer support
