GREAT FOR WELDING PIPE!

The TPWH-C Series is designed to perform orbtial TIG welds on tube and thin wall pipe without the need for wire feeding. The sealed cavity is filled with protective gas prior to and during the welding process. This weld head is very efficient and has a water cooled system. Various collet sizes are available, offering accurate positoning without tacking.

Our weld heads are made to the highest quality standards. All of our collets are made from stainless steel which provides better wear over using aluminum type collets and are designed with springs that will hold over-sized and under-sized tubing. The spring style collet provides more flexibility for various types of tubing or pipe.

  • TIG autogenous (fusion) welding without filler material
  • Precision design for accurate tube positioning
  • Tube clamping collets manufactured from 17-4 SS for repeatability
  • Closed chamber for better gas coverage and cleaner welds
  • Compact design for small work areas
  • Commonly used for stainless steel, nickel alloys and titanium
  • Water cooled head for high production and larger wall thickness
  • The tool of choice for medical, food, biological, electric, instrument and pipe installation industries
  • Recommended Power Unit = OW-ARC 180
