Thanks. They weigh between 40 and 50 pounds. Not too bad. Easy enough to hang them.
I use a plasma torch for cutting.
Most of the welding is done with a MIG welder. I have to MIGs, one with steel wire and another with silicone bronze wire. The bronze wire allows me to weld steel to brass, steel to copper, copper to brass and in this build steel to aluminum.
I also work with an oxy/ace torch.
I use a propane torch for a little bit of soldering.
Happy to answer any questions.
