ESAB launches high-performance water-cooled Tig torches
ESAB Welding & Cutting Products is introducing its SR-B 21 and XCT-B 400w high-performance TIG torches. Designed for welding professionals, these compact water-cooled torches offer small torch neck-to-head dimensions to improve access in tight spaces and enable more precise bead placement. Common features include an ergonomically formed handle with integrated soft grips that keep the handle in place with minimal grip pressure to reduce hand fatigue and Precision Switch technology for comfortable On/Off control. A ball joint on the back allow frees movement in all directions without torsion of the cable assembly, which comes in length options of 4, 8, 12 and 16m.
Because of its extra-large cooling channels, the SR-B 21 offers a 100 per cent duty cycle at 240A when AC welding and 340A when DC welding. The SR-21 B torch accepts tungsten electrode diameters from 0.5 to 3.2mm and has rigid or flexible head options.
Jan Taagaard, Global Product Manager, Torches, ESAB says: "Compared to leading competitive SR-20-style torches, the ESAB SR-B 21 provides 40 amps more output for AC welding and 120 amps more output for DC welding. The higher duty cycle rating keeps the SR-B 21 torch cooler, which increases operator comfort and allows welding for longer periods of time at higher amperages."
The torch is part of ESAB's new SR-B series of TIG torches designed for welding professionals across a spectrum of applications. The SR-B 9, 17, 26 and 26 HD are air-cooled torches with a duty cycle rating of 60 per cent at 110, 140, 200 and 230 amps DC, respectively. The SR-B 18, 20, 21 and 400 are water-cooled torches with a duty cycle rating of 100 per cent at 220, 320, 340 and 450 amps DC, respectively.
The new XCT-B 400w water-cooled torch offers ESAB's top-of-the-line construction and an even higher duty cycle while maintaining compact design. The XCT-B 400w offers a 100 per cent duty cycle at 315 amps when AC welding and 450 amps when DC welding. It features a collet design that consolidates parts - there are only three wear parts -and creates a larger mating surface between the electrode and the water-cooled torch head. This design provides more efficient electrical transfer for greater arc stability and more efficient thermal transfer to keep the torch cooler. The electrode will remain securely fixed even under an extended high-amperage load and will offer longer service life.
Taagaard says: "Further, the collet design produces a smooth, laminar gas flow that is comparable to using a gas lens. Users can increase electrode extension or hold the XCT torch farther away from the weld puddle, such as for better visibility of the joint or in a restricted access situation, yet still achieve good gas coverage and porosity-free welds."
The XCT-B 400w accepts tungsten electrode diameters from 1.6 to 4.0mm and has gas nozzle length options of 25.5 or 35mm.
