Closed Weld Heads

Closed Weld Heads

Intelligent thin-wall tube engineering installation expert-fusion head Suitable for thin-wall tube to tube welding, accurately fixing.

This is a specially designed orbital TIG welding head without wire feeding for kinds of pipe fitting. The sealed cavity is filled with protective gas before welding to ensure the quality of welds. This is one high efficiency and high quality welding head with water cooling for welding head & collect and special made collects according to customers’ requirements which can ensure accurate positioning with no spot welding. Support equipment: i-Arc200 and i-Arc400 Orbital Welding Power Source. Application: Electric, instrument, pharmaceutical, engineering installation, military, nuclear facility and so on.

  • TIG welding without wire feeding
  • Closed welding, better protection
  • Water circuit cooling design for long time working
  • Remote pendent for long distance control
  • Open window for checking alignment after assembly
  • Suitable for stainless steel, titanium alloy small diameter with thin wall thickness
  • Widely applied in medical, food, biology, electrics, instrument and pipe installation industries.
