Patent DE-4210699-A1 (DE)
Title: Soldering or welding device - with automatic level control on vaporising liq. which enriches fuel gas and controls flaming temp.
Inventor: ESSER UTZ
IPC: F23K5/00
Filed: 1992-04-01
Abstract: Soldering or welding appts. in which the electrolytically produced fuel gas passes through a container with an easily vaporised liquid which enriches the gas prior to being fed to the work area together with solder and flux. The level of liquid in the container is automatically monitored by a level sensor which causes the flow of liquid from storage container into the vaporiser via a valve control device when the actual level is below an optimal value. USE/ADVANTAGE - Esp. welding or soldering small parts. A constant level of vaporisable liquid is maintained without relying on personnel. This ensures that the welding flame temp. is kept at the required value and not under or over heating.
