HWSG-3 resistance
welding tool
Fixing the pipe ends inside the
fitting
Mark the depth of the pipe insertion into
the fitting. The insertion depth of the
pipes into the coupling must be marked
on both pipes.
Do not use any wax or grease pencils!
Insert the pipes up to the mark into the
fitting. The pipe faces must meet in the
middle of the coupling.
Fully tighten the screws of the inte-
grated pipe fixing system using a hexa-
gon socket wrench alternately. With pipe
surface temperatures of > 40 °C and the
resulting expansion, it is difficult to push
the fitting onto the pipe end because of
the necessary tight tolerances.
Functional description
1. Connect the welding tool to the power
supply, all the pilot lights will light up
for two seconds. After that, the Power
light will be on continuously.
2. Connect the welding cables to the cor-
responding fitting.
Pilot light Ready will light up.
Each of the connected welding chan-
nels will independently recognize the
connected fitting and its dimensions.
Up to three welding operations can be
carried out simultaneously and for dif-
ferent dimensions.
Welding channels that are not connect-
ed are “blocked”, i.e., without electrical
power, during the welding process.
