Closed Weld Heads

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
