What is the power of the welding machine used on the site, kW?
1, general steel welding machine about 100KVA input power, big have 150KVA, small have 63KVA.2, welding machine is also called current welder or resistance touch welding machine. By using the resistance between the two workpieces' contact surfaces, the contact surfaces of two mutually butted metal can be instantly heated, melted and fused instantaneously through a low voltage and high current.3. Power refers to the amount of work done by an object in unit time. That is, power is the physical quantity describing the speed at which the work is done. The amount of work must be, the shorter the time, the greater the power value. The formula for power is power = work / time. A physical quantity of power that represents the speed of a work. Work done in unit time is called power, expressed in P. The power is equal to the scalar action with the object of force speed product.
Generally speaking, there are two kinds, one is used for vertical and vertical rebar connection electroslag pressure welding, the model is not less than BX1-400, the capacity is more than 20KVA. If the welding bar is big, the welder needs to be increased, such as 500 or 600, and the capacity is over 30KVA. Another is for flash welding, the power is generally not less than 500
