Which wire is ideal for welding outdoors in windy conditions?

Self-shielded flux-cored wire.

Start playing free

  1. Self-shielded flux-cored wire ✔
  2. Solid MIG wire with argon
  3. Gas-shielded flux-cored wire

Why: Wind can blow away shielding gas, causing porosity. Self-shielded wire makes its own protection, so it holds up outdoors.

Huh, didn't know that: Miller says gas loss typically shows as visible porosity in the bead.

The dad joke
Two windmills are standing on a wind farm. One asks, "What's your favorite type of music?" The other says, "I'm a big metal fan."
