I think the biggest problem is due to OA tanks. Most home-owner
insurance policies have a void clause if OA tanks are on your property.
Are you OA welding? You might get around this if it's a problem by going
to propane-oxygen. Tell them you are doing explosive welding...see where
THAT gets you. (What are buds for)

Wow. I'll check my homeowner's policy. I do own a set of O/A tanks but I
almost never use 'em, mostly keep them for sentimental reasons. Maybe once
a year I have to use the cutting torch to make a meatball cut. Maybe it's
time to sell them.

I read my homeowner's policy carefully. No mention of welding whatever, no
exclusion for coverage if O/A tanks are present, nothing at all like that. - GWE
