Title:
PROJECTION WELDING MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/143483
Kind Code:
A1
Abstract:
The present invention relates to a projection welding machine, which is implemented to drive a nut feeding part of a nut feeder and a cylinder driving part of an upper holder only when an operation environment of a lower electrode part is normal, because of a distance sensor using a laser and a relay connection structure linked to the same, and thus is not driven in a state in which foreign materials (specifically, hands of an operator) are on the lower electrode part or a nut is in a bad mounting position.
