MIG with Powdercoat
Just thought I'd share this here in case it helps someone in the future.
I've found trying to MIG weld powdercoated steel a pretty dreadful experience. Grinding the weld area helps a bit, but the nearby melting coating seems to produce some gas or something that makes the arc go to hell, making a hissing sound and leaving a globby-looking bead.
The answer? Change the gas to straight CO2. Welds like a dream.
