Abstract

The utility model provides an automatic weld dolly that can external or not external power supply, includes a power supply circuit, and this power supply circuit's input is connected with the power supply end of carbon dioxide wire feeder low pressure solenoid valve, and this power supply circuit's output and welding dolly's power plug are connected. The utility model discloses a low voltage battery valve power supply of sending the silk machine, or built-in 24V storage battery is sending the silk machine out of work time power supply, need not external alternating current 220V and 110V's power, make the operator avoid the personal danger of electric shock in whole operation process, the operational safety nature of this kind of production improves to the highest level, the dolly also can be by independent DC power supply simultaneously for the operation is in the safe state of low pressure, avoids taking place the electric shock.

Description

Automatic welding trolley with or without external power supply

technical field

The utility model relates to an automatic welding trolley, in particular to an automatic welding trolley which can be connected to or not connected to an external power supply.

Background technique

Existing automatic welding trolleys for gas metal shielded welding generally use AC 220V or 110V power as the input power supply, which greatly exceeds the safe voltage of the human body and has greater danger.

Contents of the invention

The purpose of the utility model is to provide a highly safe automatic auxiliary welding trolley for gas shielded metal welding with or without external power supply.

The utility model is realized in the following way: it includes a power circuit, the input end of the power circuit is connected with the power supply end of the low-voltage electromagnetic valve of the carbon dioxide wire feeder, and the output end of the power circuit is connected with the power plug of the welding trolley.

The power supply circuit is composed of a general power supply circuit.

The utility model supplies power through the low-voltage battery valve of the wire feeder, or the built-in 24V battery supplies power when the wire feeder is not working, and does not need an external AC 220V and 110V power supply, so that the operator can avoid personal danger of electric shock during the entire operation process. The operation safety of this kind of production is improved to the highest level, and the trolley can also be powered by an independent DC power supply, so that the operation is in a safe state of low voltage to avoid electric shock.
