I learnt how to migweld and tigweld. The first technique was very simple, as the solder is inside the machine and unravels as the trigger is held down, and it is a simple matter of keeping the nozzle steady. It is easiest to use on only certain meals as he reel is difficult to change. The second technique was more difficult to use, since it was more like soft soldering on a small scale; a thin rod is placed on the surface of the sheet steel and the the nozzle melts it so that it can be used to attach it. The timing of this method is more finicky and I mostly ended up with blobs that wouldn’t be useful in holding anything together.
Knowing this will be useful as I intend to use this technique to complete my stool, as it has a continuous loop of steel around the legs.
