What is the current of a general welder?

The common welding current is 50A—200A, and the conversion success rate is10kw-50kw-50kw. The output power of different brands and models of electric welding machines is different, and the gear on the electric welding machine is also different, so the power often depends on the actual situation.

For example: welding current 200A, welding voltage 28V, output power 200 * 28 = 5.6kW..

Converted to the power supply network, it is 5.6/0.7 = 8kW (converted by a factor of about 0.7).

When the welder is not welding, the no-load loss is not big, generally around 1KW, depending on the specific situation of your welder.

principle

It uses the high-temperature arc generated when the anode and cathode are short-circuited instantly to melt the solder and the material to be welded on the electrode, so as to achieve the purpose of combination. The structure of electric welding machine is very simple. To put it bluntly, it is a high-power transformer, which turns 220/380V AC into a low-voltage and high-current power supply, which can be DC or AC. Welding transformer has its own characteristics, that is, the voltage drops sharply.
