The welding heads3. 2.
These power sources support several of the Polys-
oude series welding heads.
The open welding heads3. 2. 1.
MU IV type (Fig. 3.4) for standard or special ap-•
plications. Modular design. Weldheads designed
for butt welding pipes, with or without fi ller wire.
Polycar welding head (Fig. 3.5) to weld large •
diameter pipes.
The closed chamber welding heads3. 2. 2.
MW (Fig.3.6) when high productivity is required. •
High duty cycle due to water cooling. Adaptor
kits available for welding of accessories (elbows,
fl anges, valves, connections, etc.).
Sentry UHP for the demands of ultra high pu-•
rity welding. Welding head with closed chamber
designed for but welding thin pipes without fi ller
wire. It ensures high quality welds and its com-
pact design enables it to be used in areas with
restricted access.
HD when the access to the weld area is restricted.•
K for applications calling for the best shielding •
gas protection.
