Title:
PUSH-PULL FEED-TYPE TORCH SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/141167
Kind Code:
A1
Abstract:
The present invention provides a push-pull feed-type torch system comprising a body bundle, a feed guide unit, a sensing unit, and a control unit. In particular, the sensing unit senses the disconnection of a welding wire guided by the feed guide unit, and the control unit is configured to determine whether to continue or stop a welding operation on the basis of whether the welding wire sensed by the sensing unit is disconnected. Thus, whether the feeding of the wire has stopped while automatic welding is in progress can be accurately determined, and welding defects arising from such wire feeding stoppages can be prevented.
