Description
Leister Fusion 1 Compact Extrusion Welder is a handheld extruder for plastic repair and fabrication in pipe, tank, and container work. The slim body and attachable handle keep it controllable on tight seams, and the double-sided rod intake feeds 3 to 4 mm welding rod from either side.
Leister Fusion 1 Benefits
- Compact, slim design reaches confined seams that bulkier extruders cannot.
- Double-sided rod intake lets the operator feed rod from whichever side is comfortable on the joint.
- Attachable handle adds control and cuts fatigue on long welds.
- Integrated LED light puts clear light on the weld zone in dim work areas.
- Closed-loop air temperature control holds a steady weld temperature for consistent seams.
- Output of 0.2 to 0.8 kg/h covers small repairs through steady production welds.
Common Applications
- Plastic tank and container fabrication and repair.
- Pipe welding in PE, PP, and HD-PE systems.
- Geomembrane and liner seam work.
- Boat and marine plastic repair.
- On-site structural plastic repairs where a full-size extruder will not fit.
