Welding machine model and power are as follows:
1, AC welding machine such as: BX1, BX5, BX6, BX7, etc., there are 250A to 630A ranging from;
2, silicon controlled: WS or TIG series, such as WS160A, TIG200;
3, silicon controlled AC and DC tig welding machine, WSE series, such as WSE350A;
4, IGBT inverter DC tig welding machine, the model of each manufacturer is different;
5, IGBT inverter AC and DC tig welding machine, the model of each manufacturer is different;
6, air plasma
Welding machine
Electric welding machine
is actually a transformer with falling external characteristics, 220V and 380V AC into low voltage DC, electric welding machine can be divided into two kinds of general according to the type of output power supply, one is the alternating current power supply; one is the direct current.
Direct current welding machine can also be said to be a high-power rectifier, divided into positive and negative poles, AC power input, transformer voltage, and then rectified by the rectifier, and then the output of the power supply with the characteristics of the falling outside, the output side of the connecting and disconnecting will produce a huge change in the voltage, the two poles in the instantaneous short-circuit ignited arc.
