Known backups / known substitutes
- Other Leister welding shoes designed for different seam geometries (e.g., fillet weld, V-seam, overlap) or alternative rod diameters- Generic 8mm outside corner welding nozzles for plastic extrusion welders, though compatibility and performance may vary compared to genuine Leister accessories- Manual hot-air welding techniques with standard nozzles, which may offer less precision and efficiency for consistent corner welds.
Comparison Note
The Leister 146.643 welding shoe is a highly specialized tool, distinct from general-purpose welding nozzles. Its design is precisely engineered for creating clean and strong outside corner welds with an 8mm rod, a task where standard nozzles would be less effective or require significant manual skill. The internal air guide system is specifically tailored for seamless integration and optimal performance with compatible Leister extrusion welders, ensuring superior weld quality and efficiency for its intended application compared to less specialized alternatives.
