7.1 Push spot welding
Caution!
Electromagnetic fields!
Wear protective goggles and gloves!
Electrodes heat up!
Flying sparks!
Only use the mode “push spot welding” is the area to be welded
cannot be reached with the spot welding tongs!
– Grind sheet surface and the area between the sheets until
completely bare.
– In the welding area the sheets must have direct contact without
air gap. Otherwise welding is impossible.
– Check the condition of welding electrodes and grind them, if
necessary.
– Ensure perfect earthing to bottom sheet as close to the welding
spot as possible.
– Select mode “push spot welding” with keys CD.
– Select sheet thickness with keys EF (thicknesses of more than
2 x 1.5 = 3 mm cannot be selected!).
– Press the welding gun to the welding point with a pressure of
approx. 8 – 12 kgs.
Excessive contact pressure will lead to poor welding results!
– Keep hold of button (34) of the gun until welding process has
ended (if necessary fine-adjust with keys GH).
– Always spot-weld thinner sheets to thicker ones!
– Proceed with welding towards the grounding point.
Spacing between the welding spots approx. 20 mm.
