Spot welding device, in particular for use in bodywork construction in the motor vehicle industry

摘要

The spot welding fixture has an electrode cap (3) which is pressed against the workpieces e.g. aluminum sheets to-be-welded with one another under preset pressure, as welding electrode. The electrode cap is replaceably arranged at a shaft (2) and moved in opposing directions around a limited angle by an assigned motor mechanical drive unit (6).
