    摘要: Disclosed herein is automatic spot arc-welding apparatus comprising a pressure sensitive self-actuating device having a consumable welding electrode and an automatic feed mechanism for controlling the length of electrode consumed from one weld to the next. A delay circuit controls the welding current to continue the application of such current for a short period after termination of movement of the feed mechanism to accurately control the length of electrode which is burned off.
