The BT17 is a gas-cooled TIG torch, 8 m long, for Böhler CORE machines. It takes electrodes from 1.0 to 3.2 mm and carries 150 A DC or 105 A AC at 35% duty cycle. This is the standard version, with no current control on the handle. The price list assigns the 8 m version to the CORE 185 TIG, which comes with a BT17 as standard.
What it is for
As a spare or replacement torch for the CORE 185 TIG; in the 4 m version also for TIG welding on the CORE 165 MMA and CORE 185 MMA. Connection kits for CORE machines are listed below under Also order. You set the current on the machine; if you want to change it from the torch, choose the BT17 U/D or BT17 with potentiometer.

FAQ
BT17 or BT26?
The BT26 8 m takes electrodes up to 4.0 mm and carries 180 A DC at 35%; the BT17 stops at 3.2 mm and 150 A DC. For the CORE 210 TIG the price list specifies the BT26, for the CORE 185 TIG both.
Which consumables fit the BT17?
Standard 17/18/26 series parts: collets 1.0 to 3.2 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 8 m length gives you reach when you weld away from the machine, for example on a large structure, without moving it. For bench work the BT17 4 m is enough.
