R - SB 40 is a powerful but compact extruder, available with several handle types to give the operator a more practical, efficient and versatile instrument. STARGUN R - SB 40 is lighter if compared to our competitor’s equivalent model; this characteristic makes of our extruder an indispensable and irreplaceable instrument when it goes about jobs in which high performances and handling are required. It is equipped with a safety system that allows the operator to work only after the right temperature has been reached and spot light LEDs to illuminate the welding area.
