Resistance soldering

1/4" bar or do you mean tube

I have one of the American Beauty light capacity tweezer-style units. It has a 250 Watt variable resistance power unit. I've been using it to solder handrails and masts for r/c boat models. Mostly 1/16" - 1/8" rod, or 1/4" - 3/16" tube. The nice thing is the tweezers can act as a clamp to help hold parts in place before and after making the solder joint. The heat tends to be localized at the electrodes, so you don't need a lot of secondary heat sinks around the joint.

Thank you for the input. I've been looking at that brand of units, they seem to be the ones people prefer. I'll check that unit out. Thanks again
