Description
The Weldy booster EX3 is a handheld extrusion welder for PE and PP. Welding rod is fed into an air-heated barrel extruder, melted, and deposited through a welding shoe to form the weld.
The EX3 is the longer, higher-output member of the booster family, built for the welding volumes of civil engineering, agriculture and construction. It handles membrane welding, tank and container fabrication, and repair work on boats and aquaculture structures. Changeable welding shoes adapt the extruder to the seam, and a locking key allows continuous welding without holding the trigger.
Key Features and Benefits
Output for larger welds
Material output reaches 2.5 kg/h with ø 3 mm rod and 3.6 kg/h with ø 4 mm rod, measured with PE. A higher deposition rate shortens weld times on long seams and larger cross-sections. Actual output varies with material and working conditions.
Welding shoes for each seam
The booster EX3 is supplied with a 30/1.5 welding shoe for overlap seams. A range of sixteen interchangeable welding shoes adapts it to other seam geometries.
Built for continuous work
A locking key keeps the extruder running for continuous welds, and the rotary handle lets the operator hold a comfortable position along the seam.
Straightforward process control
An internal air guide and air-heated screw with open-loop air temperature control keep the process simple to set up and maintain.
Applications and Use Cases
Applications for the booster EX3 include:
- Landfill and mining membrane welding: joining PE geomembranes in containment projects.
- Reservoirs and canals waterproofing: welding liners for water storage and conveyance.
- Plastic tank fabrication: welding PE and PP sheet into tanks and containers.
- Aquaculture construction and repair: fabricating and repairing plastic aquaculture structures.
- Boat construction and repair: welding thermoplastic components.

Buy Booster EX3 from Global Source Middle East
On lining, tank and water-infrastructure projects, extrusion welding is often on the critical path, and the extruder has to keep pace with the job. The booster EX3 brings 3000 W and up to 3.6 kg/h of output to PE and PP work where a smaller extruder would be the bottleneck.
Global Source Middle East supplies the booster EX3 to contractors and fabricators in the UAE. The extruder ships with an overlap welding shoe. If your project involves fillet, corner or V-seams, include the additional welding shoes in your request.
Frequently Asked Questions
How does the booster EX3 differ from the booster EX2?
The booster EX3 is longer (630 mm against 500 mm) and delivers more material with ø 4 mm rod: 3.6 kg/h against 2.2 kg/h. It weighs 6.9 kg without the power cord, compared with 6.4 kg for the EX2. The EX3 comes with an overlap welding shoe, and the EX2 with a fillet weld shoe.
Is there a booster EX3 with a digital display?
Yes. The booster EX3 Plus adds adjustable extrusion speed, a digital temperature display and an LED work light, with the same output of up to 3.6 kg/h.
Which welding rod does the booster EX3 use?
PE or PP welding rod with a diameter of 3–4 mm.
