- Thou shalt place thy work in jigs
- thou shalt not weld near flammable materials
- thou shalt take great care of thy tools
- thou shalt have good ventilation
- thou shalt use goggles
- thou shalt wear gloves
- thou shalt ground thy work
My confession (and excuses/BS)...
#1 I don't purge - that's done for me when I get them refilled. I could purge the hoses but the valves leak enough that it doesn't matter anyway (though my new torch does hold the acetylene and I would consider it).
#2 secure? - just set the tank on the cart with the loose-fitting lasso-chain. It ain't gonna fall from there.
#3 Cleaning - does paint count as cleaning? Bondo-cover?
#4 jiggs! - usually a pair of vice-grips or a magnet will do. Any method of propping it together is good enough to get a bendable-tack. Then a little heating/bending helps. But no matter what the warping while welding is more sever than any jig will hold, - so keeping something straight requires side-to-side time-share-welding and possibly some post-weld heating/bending.
#5 weld near ... flammable materials - if a fire starts just take a big breath and blow it out! What-r-ya-fraid-of? Big-bad-bondo? Undercoat? Paint-fire? Baaaahhhhh shoooo - poof no problem.
#6 if the tool box fills with rain just dump the water out. When leaves fill the box just blow them off w/ some oxygen or an air-compressor.
#7 ventilation - for what? Just take a big breath and do the job. When you need another breath just blow the smoke away first so when you inhale you get fresh air.
#8 goggles are goofy - a cool pair of #5 shades are all one needs. Sure sometimes the glasses under the shades get pit-marks but by the time those build up it's time for a new pair anyway (from rubbin em on e old shirt).
#9 gloves - an occasionally burning reinforces intelligence (or recognition of one's own stupidity)
#10 grounding - not with torches! In fact, if you don't keep your work up off of the ground you get exploding pieces of the ground hitting you.
OK so I'm a SINNER now what? I DO BELIEVE IN JESUS! and Thankfully faith in Jesus brings forgiveness. Elliott PS: Merry christmas and thanks to this NG for good reading!
