Can arc welding machine be changed into battery welding machine?

Arc welding machine is a kind of equipment which uses electric arc to heat and melt the workpiece, and usually needs external power supply. Battery welder is a kind of welding equipment with battery as power supply. Therefore, in theory, arc welding machine can be transformed into battery welding machine.

The main steps of refitting arc welding machine into battery welding machine are as follows:

1. Choose a suitable battery: the selection of battery should be determined according to the requirements of welding work. Generally speaking, choose a battery with large capacity and stable output voltage.

2. Replace the power cord: remove the original power cord and connect the positive and negative poles of the battery with the power input terminal of the welder.

3. Replace the control circuit: The control circuit of the arc welder is usually powered by an external power supply, so it needs to be powered by a battery. By replacing the power supply part, the control circuit can be changed into a battery-powered circuit.

4. Adjust the current output: The current output of the battery welder is usually realized by adjusting the output voltage of the battery. The welding current can be adjusted by increasing or decreasing the battery voltage.

5. Install battery bracket: In order to carry and replace the battery conveniently, a battery bracket can be installed on the welding machine to fix the battery on the welding machine.

It should be noted that the conversion of arc welding machine into battery welding machine requires certain electronic technical knowledge and welding experience. If there is no relevant knowledge and experience, it is recommended to seek the help of professionals to ensure the safety and reliability of the modification process.

In a word, arc welding machine can be converted into battery welding machine, but a series of modification work is needed, including replacing power cord, controlling circuit and adjusting current output. The modification process needs certain electronic technical knowledge and welding experience, and it is recommended to be carried out under the guidance of professionals.
