Wear protective goggles and gloves!
Electrodes heat up!
Flying sparks!
This mode is used for spot-welding sheet metal of 2 x 1.5 mm
or more, such as e.g. frame parts and gusset flanges.
Preparations:
– Ensure precise fitting of the sheets to be welded – no air
gap!
– Clean sheets.
– Electrode arms no longer than 250 mm.
– Stable mains power supply.
– Air pressure minimum 8 bar at filter pressure reducer.
Welding:
– Select mode “Tongs – pulse welding” with keys AB.
– Select sheet thickness with keys EF.
– Keep hold of key (28) of the tongs until welding process is
cut-off automatically.
– Observe intervals of approx. 10 secs. Between spots to
prevent electrode caps from annealing.
– The pulse welding option should only be used in the
exceptional cases mentioned above.
– Overload: Continue welding once the red LED has
