How to change the DC welding machine into a two-shielded welding machine?

How to change a DC welding machine into a two-protection welding machine:

1, add a constant voltage controller and automatic control of wire feeder, can be converted to constant voltage two-protection welding machine.

2, add a constant current source of automatic control of the wire feeder and the torch can be converted into constant current welding;

Annual Beijing (Shanghai) Essen International Welding Exhibition (annual rotation between the two places), appeared in the DC hand-arc welding machine converted to welding high-tech products "arc pressure sensing wire feeder", in the common DC arc welding machine Positive output connected to the arc voltage sensing wire feeder, welding torch and ground between the sensor to sense the voltage change, change the size of the welding current and wire feeding speed.

As shown in the picture:

The "arc pressure sensing wire feeder" is a "common DC arc welding machine" modified for shielding welding, the welding efficiency is 130% of the common shielding welding machine, the spatter is significantly reduced, and the welding efficiency that the welding arc stability is significantly improved. Compared with the dedicated welding machine, the ordinary electrode welding machine is more advantageous than the "arc pressure sensing wire feeder".
