Semi-automatic gas tungsten arc welding device

摘要

PROBLEM TO BE SOLVED: To provide the semi-automatic welding equipment capable to easily produce the TIG welding wire at will by controlling the feeding speed of the TIG welding wire to be fed from a semi-automatic GMA equipment through an induction tube by the wire inching switch in a remote control box, activated by the wire feeding switch. ;SOLUTION: With a welding torch 3 equipped with a torch switch 4 effectuate semi-automatic welding of a base material 6 connected with a TIG welding power source 1 by a cable 5. Into a welding pool, the TIG welding wire 15, which is fed by a wirefeeder 8 connected with a power source 7 through the induction tube 13, is fed by a wire nozzle 4. At this time, a wire switching terminal 10 in the remote control box 9 is operated effectuating a wire feeding switch 12 installed at the wire nozzle 14 through a controlling device 11. In above-said order the feeding of the wire 15 is on off controlled at will by controlling the wire feeder 8 via power source 7.;COPYRIGHT: (C)1999,JPO
