Keeping the START button pressed
To get a welding already from the start, keep the start button
pressed for 1 to 2 sec.
This suppresses the motion, but already heats the welding rod
and the floor covering. If you release the button, the Weldmaster
starts to run.
During the first meters the temperature will rise slightly. Readjust
the temperature setting if necessary.
Adjusting the pressure of the welding wheel
The pressure of the welding wheel can be adjusted with thumb
screw (5). Screw down the thumb screw completely for welding
PVC, screw down half for welding all other types of floorings.
Automatic shut-off at the wall
If the Weldmaster
piston will automatically shut off the drive. The hot-air-gun
remains switched on, and the hot air is directed to the escape
nozzle at the side of the valve. The front part of the machine is
lifted keeping the hot nozzles away from the flooring.
Shining strips or damaged flooring are avoided by that means.
Cut the welding rod above the feed tube just before the
Weldmaster will hit the wall. You can use the loose part later to
be welded by hand into the remaining open joint.
Do not switch off the hot-air-gun. The Weldmaster is ready for
welding the next groove.
Trimming the welding rod
Some minutes after welding you can trim the welding rod in two
operations with quarter moon knife and trimming guide.
1. Trim with quarter moon knife and trimming guide, which
will leave some 0.5 mm above floor level.
2. Trim the rest with quarter moon knife.
Cooling the machine down
Having finished welding, cool the machine down with running
ventilator and heating
set to 0.
