The BT17 U/D is a gas-cooled TIG torch, 8 m long, with U/D (up/down) buttons for remote current control from the handle. Electrodes from 1.0 to 3.2 mm, rating 150 A DC or 105 A AC at 35% duty cycle. The Böhler Welding price list assigns it to the CORE 185 TIG.
What it is for
When you want to change the current on the CORE 185 TIG while welding, without leaving the weld. The U/D trigger is available separately as a spare part, so if it fails you do not have to replace the whole torch. Connection kits for CORE machines are listed below under Also order.

FAQ
Does the BT17 U/D fit the CORE 210 TIG?
The price list assigns the BT17 U/D to the CORE 185 TIG only. For the CORE 210 TIG it specifies the BT26 U/D 8 m, which takes electrodes up to 4.0 mm and carries 180 A DC at 35%.
Which consumables fit the BT17 U/D?
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 U/D 4 m is enough.
