WELDPLAST vs. FUSION – What’s the difference between these Leister extrusion welders?

WELDPLAST Series

FUSION Series

• Closed-loop system: closed-loop control of plast and air temperature
• Less welding experience required
• Integrated display and temperature probe
• Precise temperature independent of environmental factors or quality of voltage source
  
• Greater process reliability
• DVS-compliant

• Open-loop system: open-loop control of plast and air temperature
• More welding experience required
• Neither display nor temperature probe
• Output temperature depends on environmental factors and voltage source
• Output temperature should be verified with thermocouple prior to welding

Exception: The FUSION 1 is equipped with closed-loop temperature control.
