TS 8/75 universal head for welding tubes to a tubesheet

Technical specifications

Specifications are taken from the manufacturer’s technical documentation. Updated 11/06/2026.

Description

The head is centered by a mandrel, and in the standard version the pneumatic clamp and centering are already built in, so one operator runs several heads. A rotating manifold supplies the current, gas and coolant, and the cable does not twist. The arc is held by a motorized AVC with a 20 mm stroke or a programmable electrode height, and the wire is fed by a rotating mechanism directly on the head. The support feet are adjustable to any grid pitch, and the torch with a ceramic nozzle and a diffuser gives laminar gas shielding. Welding speed is held by a closed loop, an encoder runs the program by position, and the clamp and welding pendant is in the handle. Closed water cooling with glycol gives a duty cycle of 250 A/60 % and 190 A/100 %. Wire feed is up to 1154 mm/min with PC sources and up to 2085 mm/min with P6, with a 1.5 kg Ø100 mm spool or an external POLYFIL-3 for 15 kg, or POLYFIL Compact for 1.5 kg.

How to choose

The tube size determines the centering. The mandrel with two balls works on inside diameters of 10.5–60 mm, the pneumatic clamp on 15–40 mm, the reinforced pneumatic on 40–60 mm, and tubes above 60 mm are taken on request. The joint configurations cover protruding, flush and recessed tubes, welding with a back sheet, from inside the tube, a double sheet and a header chamber. The Smart Welding Station P6 with Plug & Play software, a wired or wireless touch controller and the PC sources are compatible. For small tubes without filler there is a closed head of the TS series.
