I made one some years ago with a low voltage, high current transformer from junk parks. There are a variety of ways to make on and the hand tool.

Never built a resistance soldering gun but used them at work for soldering electrical solderwell contacts to wires in multiwire cables . Solderwell contacts are contacts that have holes to insert electrical solder as opposed to crimp type contacts that have holes for installing wire that is crimped by a tool made for that purpose . The other type of connection is a pressure type contact that uses a screw to mechanically hold the wire in place , these are usually larger contacts . The unit we used for the smaller wires is available at Micro-Mark for about $ 260.00 . It has two ranges 50 watts and 100 watts , and has two types of pliers . The unit is expensive but makes soldering very fast . It is on my personal buy list when I get around to needing to solder larger amounts material . John 2.
