Resistance welding apparatus affording operator protection |
摘要 |
Resistance welding apparatus having a power driven welding head carrying a first welding electrode for co-operation with a second welding electrode, wherein the head is switched from a low-force approach operating mode to a high-force squeeze operating mode only when the welding electrodes electrically contact one another, either directly or through a workpiece therebetween, so that no gap exists in which an operator's hand or finger can be crushed between the electrodes upon transition from low-force to high-force operation.
