Embodiment

[0033] The invention relates to a high-efficiency welding combination device for manual tungsten argon arc welding with automatic feeding of fine welding wire.

[0034] Using an ordinary semi-automatic CO 2 Gas shielded welder 1 (MAG welder), dismantled as figure 1 2 heads of the welding torch shown, retain the wire feeding hose 3, the wire feeding hose 3 is as figure 2 Bellows shown; as image 3 and 4 As shown, pull out the finger-pressed switch terminal 5 on the head of the original welding torch 2 from the welding machine, and at the same time connect a Figure 4 The foot controller 6 shown; the semi-automatic CO 2 The ground wire of the gas shielded welding machine 1 is not connected with the workpiece to be welded, so that the semi-automatic CO 2 The gas shielded welding machine 1 does not form a welding current loop.

[0035] The semi-automatic CO 2 The gas shielded welding machine 1 includes a wire feeder, and the semi-automatic CO 2 4 discs of thin welding wir...

Abstract

The invention discloses a manual argon tungsten-arc welding efficient welding combined device capable of automatically feeding fine welding wires and a method. The manual argon tungsten-arc welding efficient welding combined device comprises a wire feeder, the wire feeder is connected with a wire feeding hose and a pedal controller, the wire feeder is used for arranging a fine welding wire reel and feeding the fine welding wires into the wire feeding hose, the pedal controller controls the wire feeder to feed the wires in an inching mode, the wire feeding hose can change the outlet direction, and therefore the position of the fine welding wires fed into a molten pool is controlled. By the adoption of the manual argon tungsten-arc welding efficient welding combined device, a welder holds and guides the thin welding wires by holding the wire feeding hose, the wire feeding hose has certain rigidity and restrains the thin welding wires, and the problem that manual argon tungsten-arc welding operation cannot be achieved due to the fact that the thin welding wires are too thin and too soft can be solved; and the pedal controller controls the wire feeder in an inching mode, uniform and adjustable feeding speed of the fine welding wires can be guaranteed, the problem that a welder holds the welding wires by hand to feed the welding wires into a molten pool in an inching mode to cause unstable wire feeding speed is solved, and the device is simple in structure, convenient to use and good in effect.

Description

technical field [0001] The invention relates to the field of welding, in particular to a high-efficiency welding combined device and method for automatic thin welding wire manual tungsten argon arc welding. Background technique [0002] Manual argon tungsten arc welding (GTAW) is completely controlled by the hands of the welder during the welding process. The welder generally holds the manual argon tungsten arc welding torch in the right hand and holds the straight wire in the left hand (can also be reversed). The wire specification is generally φ2 in diameter. .0mm and above and have a certain rigidity to ensure that it is basically in a straight line to facilitate the welder's fingers to control the jog to send the welding wire into the molten pool during the welding operation. For the welding wire with a diameter of φ2.0mm or less, the welding wire is too thin and too soft to realize manual operation of argon tungsten arc welding. Most of the thin welding wires are only u...
