TPWH-OA SERIES ____________________________________________________
OPEN WELD HEAD WITH AVC/OSC
Performance:
• Used for medium to thick wall stainless and carbon steel material and other alloy pipe
• Used for pipe to pipe, butt welds, flange welds, elbows, valves etc.
• Arc voltage control (AVC) and oscillation control (OSC) for multi-pass welding procedures
• Automatic all position TIG welding for tube and pipe welding with or without wire feed
• Compact design for limited radial and axial clearances
• Water cooled and highly durable torch design
• Optional remote or integrated wire feeder
