Relatively speaking, which one is better for DPM welding machine coil or electronic

Coil type DPM welding, the term is called: tapping type silicon rectifier DPM welding machine.

Electronic welding machine is the wrong call: is the inverter welding machine. Including inverter type DPM welding machine.

The welding machine technology content and advanced degree of ranking is: tapped silicon rectifier DPM welding machine, silicon controlled (thyristor) type DPM welding machine, inverter DPM welding machine (including MOS-FET field effect tube, single tube IGBT, IGBT module).

Tap type silicon rectifier welding machine working frequency is the lowest, welding motor characteristics of the worst, there are only a few fixed welding current gear adjustment, can not fine-tune the welding parameters. The end of the wire up the most small balls. Power consumption is the largest, the advantage is relatively durable, belongs to the elimination of models.

In order of silicon controlled welding machine, working frequency 2KHZ ~ 3KHZ, welding current, welding voltage can be infinitely adjustable, the weight of the welder, power consumption, the ball is a good improvement.

Finally, the inverter welder, the working frequency of 20KHZ ~ 200KHZ, the welder is light weight, energy saving and power saving, welding maneuvering characteristics are good, the least small ball, the use of waveform control technology spatter greatly reduced to reduce the current application of the most widely used mainstream of the two bonded welding machine.
