(1) Push the wire push-wire type wire sent wire wheel push to reach the torch hose and semi-automatic MIG gas shielded Mig Welding Wires feed way. The way of the wire feed welding torch structure is simple, lightweight, more convenient operation and maintenance, but the wire feeding resistance. With the longer hose, wire stability variation, general wire feed hose length is about 3.5 ~ 4m. (2) drawing style drawing style can be divided into three forms. A reel and torch to separate the two wire feed hose connection. Another is that the reel is mounted directly on the torch on. Both are applicable in the filaments of semi-automatic welding, but the former is more convenient operation. Another is to not only separate reel and torch, but wire feed motor with torch separate wire feed can be used for the automatic metal arc gas shielded arc welding. Maximum (3) Push the wire drawing style way of wire feed, wire feed hose can be lengthened to about 15m to expand the operating distance of the semi-automatic welding. Both rely on the back of the wire forward thrust, but also by the pull of the front, the two forces work together to overcome the resistance of the wire in the hose. Push two drawing power in the commissioning process should be certain with the, as far as possible to sync, but the pull-based. Welding Wires Manufacturer sent to the process, always keep the wire in the hose in a straightened state. This wire feeder approach is often used for semi-automatic metal arc gas shielded arc welding.
