Dual shield welding wire

[Ch3No2]

How many are using this wire and what are your thoughts
Thanks in advance

I use dual shield (flux core w/ shielding gas). I like it a lot mostly heavier type welding 3/8 and up.

We have gone to it for any steel or stainless over 1/4". You can run much faster than solid wire.

Currently I am welding my engine stand head plates (5/8"thick) to a 3/4" thick collar washer and stitching the weld...very time consuming and the penetration seems like it could be better. I really dont want to arc weld them on and someone told me about dual shield. Are there any welder modifications that will be required?...Miller 250
Thanks again in advance

I've been thinking about switching over to this as well. I like how it is much quieter to use. Of course price is going to be a big factor.

Faster and easier to use. I like it, but... It's royal pain to get the heat and wire speed set right compared to MIG.

We use it at work for welding on Navy ships. It is required for wire feed welding, mig is not acceptable by Mil-Specs. Set the machine up right and you could have the wife weld it for you, super easy once you get it set right. We use LN-25s w/ a Miller Max-Star, works fine.

Dual shield works great! Use it all the time in boilers and other pressure vessels. Its not short circuit or globular transfer though. Its a spray arc and runs high deposition rates. The gas plume coming off the weld is nasty though so use some kind of ventilation control or a respirator.

This post is at a perfect time for me, I have to weld inside the water jacket on a stainless (magnetic) out door wood boiler, non pressurized system. Great info here guys, thank's. I have a question though, with duel shield do I need to reverse the polarity like I would for flux core or do I keep it neg ground like straight mig welding? I am not afraid to contaminate the weld with mild steel becouse it looks like that is what they did (poorly) at the factory, all the welds are coated in rust what are a couple more going to hurt.

What about using argon/CO2/oxygen(tri mix) mix to get you into spray transfer?
Cheaper than buying a roll of wire for one project.
