I've been lurking here and on alt.metalworking for a while now, and have a question I need help with. I'm looking to find out the most appropriate torch and gas to use for my tasks.
For the most part, I do ornamental metal work using 1" or less copper tube, thin copper plate, some brass, and mild steel (generally less than 1/4 inch rod and 1/8 inch plate.
I currently use a MIG machine for welding the steel, and a small cheap handheld propane/MAPP torch for soldering the copper. I am having a hard time soldering copper to steel when larger pieces are involved. I'd also like to use some aluminium and stainless steel in the art but haven't tried that yet.
Whatever I choose, I'd like to be able to run the torch off a 10' peice of hose to a larger tank than the little small ones.
My choices have been narrowed down to
1) buying a O/A rig and renting some tanks. Looks like at a minimum I'd be spending about $300. 2) Buying a TurboTorch LP-1 propane/air rig - would cost me about $200.Will the Rothenberger and/or Turbo Torch get hot enough with propane or MAPP to join aluminium to copper and steel? Can I braze 1/8 steel with either of these?
Cost is a consideration, cutting capability is not.
Thanks,
