1.3 Weld head
W009315
The weld head contains a U-shaped rotor gear that moves
the tungsten electrode orbiting the non-moving tube. The
head totally encloses the weld joint and allows the interior
of the head to be ooded with shielding gas. The system
includes water cooling for heavy duty cycles.
Control panel is in the handle, and assembly to the
controller is provided by a 7.5-metre hose (longer cables
are available).
The weld head is clamped on tubes by changeable collets.
It includes a chamber for shielding gas. Spesic collets are
recommended for each tube outer diameter (OD).
