Key Features
- Superior Current Conductivity: Full pure-copper inner core ensures low-resistance, stable high-current output — minimising heat build-up during extended use and maximising working efficiency.
- Safe Insulated Housing: High-strength flame-retardant rubber and plastic shell provides excellent electrical insulation, resists abrasion, impact, and elevated temperatures typical of welding environments, reducing the risk of electric shock and extending service life.
- Secure Threaded Locking: Precision-machined threaded connection creates a tight, firm contact between plug and socket, preventing accidental disconnection mid-operation and ensuring a consistently stable welding process.
- Universal Compatibility: Standard DKJ10-25 and DKJ35-50 specification design fits the majority of mainstream welding machine models — no additional adapters or modifications required.
- Tool-Free Installation: Non-slip knurled grip on the plug surface lets you tighten or remove the connector by hand, simplifying replacement and saving valuable workshop time.
