18. Thermal shrinking – copper electrode – flat
18.1 Shrinking with the copper electrode – flat
In both modes, you can also use the copper electrode – flat (CBR-U-B22) instead of the copper electrode – ball (CBR-U-B12),
however, this is not rolled over but pressed onto the excess material at specific points with the flat head. This reduces the
formation of dents during the shrinking process and avoids any reworking that may be necessary.
Important notes: Applying no or too little contact pressure with the electrodes can lead to burnout of the sheet metal! Cool
the heated sheet metal with a damp sponge.
Please note: Do not make any changes (e.g. by regrinding) to the copper electrodes, as their shape is specially calculated
– occasional cleaning with sandpaper (400 grit) is sufficient.
Shrinking with the EasyTool, slide hammer or hand puller
For small spots and points where bulges are too high, you can also shrink with the EasyTool, slide hammer or hand puller.
Connect the tools with the cable for the EasyTool and the EasyTool socket in the PS.
Select program 3: Automatic on the PS and place the tools with their welding tip on the spot with the excess material – at
the start of the welding process press the tool against the deformation while turning the handle.
Pressing lightly on the handle when welding on creates a small indentation at each point.
