Problems solved by technology

The conventional heating and power supply method is: using an AC transformer to directly change the power supply voltage of the gas shielded welding host from 380V to AC36V, and at the same time generate DC 24V through conversion. The power frequency transformer that meets this standard needs 300W~400W, and the volume and weight are relatively large. Conducive to operation

Embodiment Construction

[0008] see figure 1 As shown, the high-frequency auxiliary power supply device for gas shielded welding is mainly composed of an inverter output device 1, a high-frequency transformer 4, a heater 5, and a wire feeder 6. One end of the high-frequency transformer 4 is connected to the inverter output device 1. The other end is connected with the heater 5 and the wire feeder 6 , and its inverter output device 1 is also connected with a welding transformer 3 at the same time, and a relay 2 is arranged between the inverter output device 1 and the welding transformer 3 .

[0009] When welding is not welding, the relay 2 is disconnected, the welding transformer 3 does not work, and the voltage of the inverter output device 1 is applied to the high-frequency transformer 4 to generate 36V high-frequency heating voltage, which is supplied to the heater 5.

[0010] When welding, the relay 2 pulls in, and the inverter output device simultaneously supplies the welding transformer 3 and the...

Abstract

The invention relates to a high-frequency auxiliary power supply device for gas shield welding, which mainly comprises an inverter output device (1), a high-frequency transformer (4), a heater (5) and a wire feeder (6), wherein one end of the high-frequency transformer (4) is connected with the inverter output device (1), and the other end of the high-frequency transformer (4) is connected with the heater (5) and the wire feeder (6); the inverter output device (1) is simultaneously connected with a welding transformer (3); and a relay (2) is arranged between the inverter output device (1) and the welding transformer (3). The high-frequency auxiliary power supply device for the gas shield welding has the beneficial effects that a high-voltage variable frequency transformer is used for supplying power, so that the volume of a heating power supply transformer is reduced by two thirds, and the weight is reduced by three quarters, and miniaturization of a complete machine for gas shield welding can be much better carried out; furthermore, the high-frequency auxiliary power supply device is designed to be light and portable, so that the product is more convenient to use.

Description

technical field [0001] The invention relates to a power supply device for heating a pressure reducing valve of a carbon dioxide gas shielded welding machine and powering a wire feeder. Background technique [0002] The pressure reducing valve of the carbon dioxide gas shielded welding machine needs to be heated, and the heating power supply index is AC36V150w~250w. At the same time, the wire feeding mechanism needs a DC 24V 100W~150W driving power supply. The conventional heating and power supply method is: using an AC transformer to directly change the power supply voltage of the gas shielded welding host from 380V to AC36V, and at the same time generate DC 24V through conversion. The power frequency transformer that meets this standard needs 300W~400W, and the volume and weight are relatively large. Conducive to operation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a power supply device suitable for heati...
