High-Frequency Micro Welding Inverter
iSpot
High-frequency MFDC inverter (10–15 kHz) for precision micro and small-current resistance welding — available in 0.5 kA, 1 kA, 4 kA and 8 kA classes.
Description
iSpot is engineered for fine resistance welding tasks where current control accuracy in milliamperes and millisecond timing matter most. Operating at 10–15 kHz with a tight current loop, it delivers exceptional repeatability on thin foils, plated terminals, sensor leads and battery cell connections. Four power classes cover everything from sub-amp jewellery work to industrial micro spot welding.
Key Features
- ●10–15 kHz high-frequency inverter for ultra-fast current control
- ●Four power classes: 0.5 kA, 1 kA, 4 kA, 8 kA
- ●Secondary voltage 8.0–10.0 V depending on class
- ●Excellent repeatability on small parts and thin materials
- ●Compact form factor for benchtop and laboratory use
- ●Process monitoring with weld-by-weld traceability
Application Examples
Battery cell tab and busbar welding (cylindrical and pouch cells)
Sensor and connector lead micro spot welding
Thin foil and shim welding on precision assemblies
Medical device contact welding
Jewellery, electronics and watchmaking applications
