Welding and fumes

Two weeks ago I had my fuselage sandblasted and coated with two-part
epoxy. I had to get it primed prior to welding because it's going to
be outside and I need the 4130 tubing to be protected.

Prior to welding a tab, I used the torch to burn off the epoxy
coating. I noticed lots of fumes.

Is there a better way of removing the epoxy coating?
Are there any other precautions I should take beside simply trying to
keep my face out of the fumes? - Mike

Sandblast it off with Black Beauty (slag) or steel shot. Walnut
shells won't do squat. Glass beads might work.

You could also try chemical strippers - depends on the epoxy. Use the
nasty Methyene Chloride stuff, epoxy just sneers at the "green"
strippers, for the most part.

I'd go with the bead blast or shot blast. a dust off after leaves no
residual surface chemicals to stuff up the weld.

ballottini at 150psi will make short work of the epoxy.
well it would take my polyfiber 2 pack epoxy back no problems at all.
