Powerful extruder
The WELDPLAST S4 extruder from Leister is available in two designs: one option suited for equipment and container construction with a lateral, hot air nozzle, and as a civil engineering version with a top-mounted, pre-heating nozzle. Depending on the variant chosen, the user can process welding wire with cross sections of 3 and 4 (0.12 and 0.16 in) or 4 and 5 mm (0.16 and 0.20 in). The high powered, brushless blower guarantees excellent pre-heating for the high output class.
