The folks at the Italian site Modellismo Hobby Media sent us this email:
During the Spielwarenmesse (German toy fair) the model company ROBBE showed the WELMA 2000: a tool supposed to be the World's smallest electronic spot-welding device.
This electronic spot-welding device has been specially developed for producing assemblies from steel wire. The point where the wires meet is fixed together using a pair of pliers whose tips take the form of welding contacts; when the start switch is pressed, the joint is firmly welded together.During the welding process a current of up to 2500 A flows through the contacts for a few thousands of a second.
The WELMA 2000 will sell for 124 Euros (about US$157). No word on availability in the US.
