• Most popular tube to tube-sheet welding expert
• Suitable for tube to tube-sheet welding, with self-fusion or wire feeding, AVC tracking and no-twist designing

Product Description

This is a specially designed TIG welding head for tube to tube-sheet, which is used for carbon steel, stainless steel, mainly for protrusion tube and flush tube connection with or without wire feeding. The standard one is small torch; it can weld high protection requirement material such as Titanium alloy with tow cover. OD ≤32mm, use positioner and manipulator to fix; ≥32mm, use mandrel to fix.

Support equipment: i-Arc400 Programmable Orbital Welding Power Source.

Application: chemical, food, medicine, heat exchanger, power plant, military facility, nuclear facility and so on.

Features

• With/without wire feeding TIG DC/Pulse welding
• No-wire-twist design and special wire feeding design to meet complex single- or multi-layer welding requirements
• Durable welding torch design, suitable for tungsten electrode up to Φ3.2mm, improve duty cycle significantly
• Pneumatic expandable mandrel for positioning, connecting to the balancer accurately and reliably, which is suitable for tube to tube-sheet structure welding in boiler industry
• Compatible with manipulator and suitable for heat exchanger industry
• Suitable for materials of carbon steel, stainless steel, zirconium alloy flush tube and protruded tube
• Unique arc length control AVC design
