The BT26 with potentiometer is a gas-cooled TIG torch, 4 m long, with a potentiometer on the handle for remote current control. It takes electrodes from 1.0 to 4.0 mm and carries 180 A DC or 125 A AC at 35% duty cycle. The Böhler Welding price list assigns it to the CORE 185 TIG and CORE 210 TIG.
What it is for
When you want to set the current on the CORE 185 TIG or CORE 210 TIG with the potentiometer on the torch and need electrodes up to 4.0 mm. The potentiometer trigger is available separately as a spare part. Connection kits for CORE machines are listed below under Also order.

FAQ
Potentiometer or U/D?
Both BT26 versions control the current from the torch and share the same ratings: 1.0 to 4.0 mm, 180 A DC and 125 A AC at 35%. On the BT26 U/D 4 m you change the current with up/down buttons, here with the potentiometer.
Can I replace just the potentiometer trigger?
Yes, it is a separate item: Potentiometer trigger for remote current control, BT17 and BT26.
Which consumables fit the BT26 with potentiometer?
Standard 17/18/26 series parts: collets 1.0 to 4.0 mm, collet bodies in the same sizes, ceramic nozzles from No. 4 (6.4 mm) to No. 12 (19 mm) and a long or short back cap. Match the collet and collet body to the electrode diameter.
4 m or 8 m?
The 4 m length is enough at a bench or close to the machine, and the torch is easier to coil up. If you weld further from the power source, for example on a large structure, choose the BT26 with potentiometer 8 m.
