(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.
(1) control the start and stop of welding equipment. (2) control the action of the electromagnetic valve in advance aspirated and the lag to stop the gas, the Welding Accessories is well protected. (3) control the water pressure switch action to ensure that the torch to be a good cooling. (4) Control the arc extinction: MIG welding arc are generally three types: the burst off the arc (wire contacts the workpiece, the power to make the wire in contact with the workpiece at the melting wire explosion ignited the rear arc); slow send wire arc (wire slow to send to the workpiece until the arc is ignited, then increase the wire feed speed), and the Withdrawing arc (wire contact with the workpiece, power Withdrawing the wire ignited arc). Extinction in two ways: the current decay (wire feed speed corresponding decay, fill the crater, to prevent the wire and workpiece adhesion) and wire back to burn (to stop the wire feed welding power, cut off after a certain period of time). (5) controls the wire feed and car (or table) mobile (automatic welding). Program control is automatic. Semi-automatic welding start switch mounted on the handlebars. When welding after the start switch is closed, the entire welding process in accordance with the procedures set automatically. Program control of the controller by the composition of the delay controller, arc controller, put out the arc controller. Process control systems will be Welding Wire China, wire feeding system, torch and walking systems, gas and cooling water system organically combined, form a complete, automatic control system of welding equipment. In addition to the programmable control system for high-end welding equipment parameters automatically adjust the system. Its role is to changes outside interference when the welding parameters can be automatically adjusted in order to maintain the welding parameters constant, to maintain normal and stable welding process.
