Product Description
GB4706 Thermocouple Welding Machine
Portable Thermocouple Welder
Product Overview
This portable thermocouple welding machine complies with GB4706 standard requirements and is specifically designed for fine-wire thermocouples and node welding applications. The unit handles wires up to ≤Ф0.5 mm diameter, providing precision welding capabilities for industrial temperature measurement systems.
Safety Features
The welding unit incorporates Class III safety structure with low voltage power supply, ensuring operator safety during operation. Both the graphite electrode and electrode holder can be safely touched during use. Proper grounding connection to the power socket is essential for operator protection.
Technical Specifications
- Power Supply: 220V ±10%, 50Hz, 200VA
- Welding Capacity: ≤Ф0.5 mm thermocouple wires
- Safety Class: III category structure
- Dual Power Levels: I and II gear settings
Operating Procedure
| Step | Procedure |
|---|---|
| 1 | Position welding machine on worktable left side. Separate electrode holder and graphite electrode, securing graphite electrode lead wire with weight or double-faced adhesive tape. |
| 2 | Connect to 220V power supply and turn on rear power switch. Power indicator light will illuminate. |
| 3 | Select power level: Use I gear for wires under Φ0.25mm or smaller weld joints. Combine I and II gears for larger diameter thermocouples. |
| 4 | Press energy storage switch lightly. Wait until indicator light extinguishes, indicating energy storage completion. |
| 5 | Strip thermocouple wire jacket (20mm) and core wire (5mm). Splice two core wires and clamp metal portion on specially processed electrode holder, exposing 2-3mm of splicing section. |
| 6 | Hold thermocouple wire and electrode holder, positioning exposed core wire perpendicular to graphite plane. Welding completes with audible "clap" sound. Press energy storage button for next cycle. |
| 7 | Inspect weld spot: Diameter should be minimal (typically twice wire diameter), spherical shape, pore-free, smooth surface with metallic luster. |
WARNING: Welding is strictly prohibited when the energy storage indicator is illuminated!
