BUYING GUIDE
Understanding Wire Diameter
When choosing wire for dual shield welding, the diameter is your most important decision.
* .035 Wire: Best for thinner materials (1/8″ to 1/4″) and lower amperage machines. It gives you more control but slower deposition.
* .045 Wire: The “Goldilocks” size. It handles everything from 1/4″ to 1″ plate and is the standard for most fabrication shops.
* 1/16″ Wire: Reserved for the big stuff. You need a powerful 300+ amp machine to run this effectively, but it puts down metal faster than anything else.
Gas Requirements and Machine Power
Don’t forget that dual shield welding requires a shielding gas, typically a 75% Argon / 25% CO2 mix. This is what gives you that clean, spatter-free finish.
* Power Source: You need a DC constant voltage (CV) power source. Most MIG welders work, but check your duty cycle; dual shield draws a lot of current.
* Drive Rolls: Because flux-core wire is hollow, you should use V-knurled drive rolls to prevent crushing the wire while still maintaining a solid grip.
Safety and Comfort
The radiant heat from this process is much higher than standard MIG or Stick welding.
* Heat Shields: As I’ve shown, an aluminized hand shield is a game changer. It reflects the infrared heat away from your glove.
* Fume Extraction: This process produces more smoke than solid wire. Always weld in a well-ventilated area or use a fume extractor.
Common Questions About Dual Shield Welding
How Do I Choose Dual Shield Welding Wire?
You should choose your wire based on the thickness of the metal and the power of your welder. For home shops with 220V machines, a.045 E71T-1 wire is usually the best all-around choice for structural repairs and fabrication.
What gas is best for dual shield welding?
The most common and effective gas is a 75% Argon and 25% CO2 mix. This provides a very stable arc and great puddle clarity. You can use 100% CO2 for deeper penetration and lower cost, but it results in slightly more spatter.
Can I use a regular MIG welder for this process?
Yes, as long as your welder has enough amperage (usually 200A or more for.045 wire) and the ability to hook up a gas bottle. You will also need to switch your polarity to DCEP (reverse polarity).
Why is the slag hard to remove?
If your slag isn’t “peeling” off, you might be running too cold or your travel speed is too slow. Increase your voltage slightly to flatten the bead, and the slag should pop off much easier.
Is dual shield better than solid wire for outdoors?
Yes, it is much better. Because it has an internal flux (like stick welding) in addition to the gas shield, it is far more resistant to wind than standard MIG welding, though you should still use wind screens in heavy gusts.
