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. Spesic collets are
recommended for each tube outer diameter (OD).
