I’ve always been leery of cad welding to a rohn 20/25 so we just clamp them – we’ve had too many fence posts burn through – I’d hate for the same to happen to a tower leg. We use #2 solid tinned copper for the wire. A couple of things on the molds – try to be creative – for instance if you know you need a ‘T’ mold – buy a ‘+’ mold instead and just push the wire through the mold. Same goes with the mold for the wire to ground rod – we buy molds with parallel wire passing through rather than a dead end to the rod. If the wire is dead ending, toss a short piece of scrap to plug one of the wire holes and push the other wire through.. It really keeps the number of molds down to a minimum and allows more flexibility overall.

We do it to them just like what you are describing, but we weld to the guy wire plate not the wire itself. All kinds of youtube videos of it.

Copper to zinc would not be a strong weld, and it would start some kind of galvanic reaction, not to mention weakening the cable. copper-copper will work, but I don't think it's actually welding, I think it might be brazing? bp<part15sbs{at}gmail{dot}com> On 3/23/2015 2:01 PM, Ken Hohhof wrote: I was not aware you could cadweld to guy wires.

We basically need to do 3 types of welding for towers. 1) Welding copper ground cable to the guy 3/16”, ¼” and 5/16” wires 2) Welding copper ground cable to ground rods 5/8” 3) Welding copper ground cable to Rohn 25G and 45G tower piece. Looking at lots of models, pieces parts. Anybody have some practical suggestions on pieces parts, vendors etc? Thanks! Paul McCall, Pres.
