I don’t understand the reason for dual shield welding. Please help me understand.
1. Since you are using gas with dual shield, you have the same problems with the gas blowing away like standard mig.
2. With dual shield you also have the same problem with slag remove, to a lesser extent as with flux core welding.
Now, if you are welding where wind is not a problem (inside), what’s the advantage of dual shield over regular mig??? Next, and a may be wrong here but it seems dual shield wire is more expensive than regular, and you also have expense of running gas with the dual shield.
Last, as I understand, leaving out stick welding, Flux core is the only option for outside, winding conditions.
So, where is my common sense failing so badly?????
