I just noticed this thread so I will put in my two cents worth a few times and maybe go for a dimes worth.
1. Welding hooks I did not see anyone mention that you can buy weld on hooks made for welding to things they are a hook with a flat side that makes it easy to weld. I got mine pretty inexpensively from a tow truck supply company. I dont remember the name of it but someone from TBN suggested it so you can probably do a search and find it.
2. I noticed someone asking patg about a hardoned surface and he mentioned hardening rods. You can also get a wire for wire feed welders that will allow you to surface harden things. I have seen it available but it is a bit pricey. I have a friend that sharpened the blades on his brushhog then ran a bead over them with a hardening rod and he said it was amazing how much of a difference that made.
3. Duty cycle- my welder has something like a 40 per cent duty cycle at the maximum rated amerage of 175 amps. When I looked at the specs you only have to come down a few amps. Something like maybe 150 and then it was showing 95 per cent. I have found that I have only used the maximum setting on my welder one time.
I realize that is only 6 cents worth but there will be other threads
