Medium Frequency Resistance Welding Transformer Series | Welding Equipment Accessories
Our medium frequency resistance welding transformer is a core matching part for medium frequency inverter resistance welding machines. Adopting advanced nano-amorphous iron-based core material and circulating water cooling structure, this series welding transformer features low energy loss, stable DC output, and compact size. It is widely matched with various spot welding machines, projection welding machines, and automatic welding equipment for metal welding production.
1. Major Functions & Core Features
- Complete Integrated Structure: Composed of a rectifier module, high-performance iron core, copper windings, and a closed water cooling circulation system, ensuring stable long-term operation.
- Typical Electrical Characteristics: Designed with low secondary output voltage and high output current, perfectly matching the working requirements of resistance welding.
- Intermittent Working Mode: Matches low continuous duty cycle, suitable for intermittent industrial welding production.
- Strong Power Transmission: Offers excellent and stable high power transmission capacity to meet heavy-load welding demands.
- Dual Optional Working Frequency: Supports 1kHz and 4kHz operating frequency for different welding process needs.
- Stable DC Output: Direct DC current output lowers inductive effect of secondary circuit, effectively improving overall thermal efficiency.
- Optimized Welding Effect: DC output optimizes current skin effect to concentrate welding heat precisely on welding spots. It reduces peripheral heat-affected zone greatly, which is highly suitable for multi-layer plates and thick metal plate welding.
- Premium Nano-amorphous Iron Core: The transformer core adopts nano-amorphous iron-based strip material. It owns superior performance including high magnetic flux density, high permeability, high Curie temperature and excellent thermal stability. Meanwhile, it realizes low eddy current loss, low core loss and high magnetic induction intensity compared with traditional silicon steel transformers.
