HWSG-3 resistance
welding tool
Special features
• Integrated coding enables recognition
of the particular fitting and its dimen-
sions.
• Fully automatic welding process after
pressing the start button. Therefore,
errors due to setting the wrong pa-
rameters cannot occur.
• Beginning and end of the welding
process are signalled visually as well
as acoustically.
• Faults during the welding process are
indicated.
• Simultaneous welding of up to three
connections of different sizes.

The welded parts require a cooling pe-
riod before use.
Welding preparation
The welding tool and the welding areas
must be in a clean and dry condition.
Cut the pipes at a right angle and
– where necessary – deburr inside and
outside.
Do not chamfer the pipe ends!
Use suitable plastic pipe cutters.
Clean the joint surfaces of the parts to
be welded (fitting and pipe) immediately
before welding. Use absorbent, non-lint
paper (only moistened) and an ethyl
alcohol based cleansing agent and thor-
oughly clean the pipe and fitting.
