摘要:
A gas tungsten arc welding torch includes a handle and a nozzle located distal of the handle and having a central bore. First and second tungsten electrodes are located partially within the central bore of the nozzle. The torch includes at least one filler wire channel that terminates radially inward of the first tungsten electrode and the second tungsten electrode. The torch includes a torch trigger. Operation of the torch trigger controls delivery of a first filler wire and a second filler wire through the at least one filler wire channel. The torch includes a wire feed speed control. Operation of the wire feed speed control adjusts a wire feed speed of both of the first filler wire and the second filler wire.
