I am trying to reinforce my hanging furnace, It is hanging from the ceiling of my garage by threaded rod. I would like to add some earthquake enforcement but can’t seem to find and data on the strength of the steel angles I would like to use. I tried contacting [url]www.steelworks.com[/url] which sells in home depot and lowes but they don’t provide load tables. I figure the furnace and ductwork and about 150 lbs, I would like to add a additional set of chains from the ceiling to the heater and run a 14 gauge steel angle underneath (the one you buy with the holes in it.) Will a 14 gauge steel angle hold the weight of 150lbs with the chain connected to it.

Despite advice to the contrary in these forums, I went ahead and bought a cheapo welder from Harbor Freight for $179.00 (refurbished and made in Italy, model 151 T/2). For the record, I’ve never done any welding nor do I think I’ve ever seen anybody doing welding. I received it today, and after some brief assembly like putting the wheels on, I gave it a try. It needs 230volt 20-amp ac power and has a maximum output of 120 DC amps for welding. I didn’t receive the wire I ordered yet but it came with about 20 feet of 23-gauge wire that I think has a flux core. It can use gas but I don’t have it. Anyhow, originally the best I could do was to make thousands of tiny BB’s. Eventually I was able to run a nice bead that I was pretty proud of. I was trying to copy the bead that’s visible on some of my patio furniture. I didn’t do near that well but I was getting better, then I ran out of wire. I’m a retired EE and plan to do some overload testing on it when I receive the wire and before the 30-day refund expires. If it fails, I’ll let you know.
