Can the secondary protection welding machine be used as a DC manual arc welding machine?

1. Yes, the arc characteristics of the two welding methods are different. The KR series cannot meet the requirements unless modified, but it is not recommended.

2. You need to buy an AC regulated power supply.

3. Most manual welding can be replaced by CO2 welding, and it is more efficient.

4. Instead of welding wire, ER50-6 can be used, which is very commonly used.

5. I think the 100% temporary load of 500A you mentioned is too high. It is not actually used. There is a limit to the current density. The diameter of the welding wire only needs to match your welding gun, and 1.2 is more commonly used. Flux-core welding quality is good, but I guess solid-core welding will be enough in your case.

6. CO2 is oxidizing at high temperatures, so aluminum cannot be welded with CO2.

7. Inverter welding machines are very expensive, especially foreign brands, such as Phoenix, but if you consider the overall cost, they may be comparable to your KR series, and the welding quality is much better, provided that the workers are of sufficient quality. high.
