What's the difference between a spot welder and an electric welder?
Spot welding machine is heated by the current welding parts itself, so that its contact parts after melting, cooling, welding, welding machine through the current heating solder or welding rod and welding parts to melt welding. The iron is heated by the electric current, the resistance wire is heated and transmitted to the iron head, and the soldering head is contacted with the welding piece and the solder to melt and finish the welding.

Spot welding machine, welding machine, soldering iron difference:The double point welding current welding principle, when the two electrode pressure workpiece makes two layers of metal forming some contact resistance in the two electrode pressure, welding current from the electrode through another electrode is formed on the two point contact resistance moment of welding, and the welding current from another the two part flow along the electrode with the electrode to form a loop, and will not hurt by the internal structure of welders.
