this is great help, thanks. I'm a retired insurance guy and an old volunteer fireman, and for sure I am determined not to burn my barn down, so....probably a bit overkill, but better safe than sorry:
2 6x8 foot welding screens, together they will block off the welding area from everything else
2 welding blankets
a good autodarkening helmet with a 2x magnifier inside (still have to install that)
gloves, non flammable shirt
2 10ABC fire extinguishers plus one pressurized water, all commercial grade
a separate electrical circuit just for the welder (I wound up rewiring my entire barn for this...groan)
a welding table, all the gadgets from Harbor Freight, clamps, magnets, etc.
what I really need is a comfortable sitting position to do this welding.
very bad arthritis, fused neck, etc, can't bend over a lot so must find comfortable position.
Luckily the working height of the mower deck can be changed once I figure out distances, length of rod,
all the stuff you experienced guys take for granted.
wish my barn was heated, this is not the week for welding, way too cold in there. Well, at least for the welder...
