Thermocouple Welding Machine With IEC 60335-1 For ≤Ф0.5mm Filament Thermocouple

Test Procesures:
 
1. Put the welding machine on the left side of the work surface, separate the welding tongs and the graphite electrode on the desktop, press the lead wire of the graphite electrode with a heavy object, make any plane of the graphite electrode flat or stick the graphite electrode on the chassis with double-sided tape above.
2. Plug in the power plug (220V±10%, 50HZ, 200VA), turn on the rear power switch, and you can see the power switch indicator light on.
3. Adjust from I to II as needed. When welding the thermocouple wire below Φ0.25mm or if you want to weld a smaller diameter of the junction, it is recommended to use I. As the diameter of the thermocouple increases, I can choose I + II.
4. Touch the energy storage switch, and the energy storage is completed when the energy storage indicator goes out.
5. Strip the thermocouple wire sheath to about 20mm with wire strippers, then strip the metal core wire to about 5mm long with wire strippers, twist the two core wires, and clamp the metal part to the specially treated " Welding gun", the spliced ​​part is exposed by 2 to 3mm.
6. Grasp the thermocouple wire and the welding tongs with your fingers, so that the core wire exposed on the welding tongs touches the graphite plane perpendicular to the graphite plane, and the welding is completed when you hear a crisp sound of "pop". Press the charge button again to get ready for the next cycle.
7. Check the solder joints. The diameter of the solder joints is required to be as small as possible, usually twice or slightly larger than the diameter of the thermocouple wire. The joints are spherical, without pores and inclusions, with a smooth surface and metallic luster.
Warning: Welding is prohibited when the energy storage indicator is on.
