The Weldy Booster EX2 and Booster EX3 are the two hand extruders we quote most often in the UAE — and because they share the same voltage, wattage, wire sizes and welding shoe system, buyers regularly ask us which one they actually need. The honest answer: they're built for different working rhythms, and picking by price alone gets it wrong in both directions.
Here's the complete comparison, based on the machines' real specifications and what UAE fabrication shops and lining crews report from daily use.
Quick Verdict
Choose the Weldy Booster EX2 if your extruder does mixed duty — fabrication one week, repairs and site details the next — and agility in tight spaces matters. Choose the Weldy Booster EX3 if you weld long structural seams daily and output per hour decides your deadlines. Crews that do both at volume often end up running one of each, sharing a single consumables shelf.

The Differences That Actually Matter
1. Output: 2.5 vs 3.4 kg/h — a 35% Productivity Gap
Both machines draw 3000W, but the EX3's barrel extruder converts it into roughly a third more weld material per hour. On a repair job that difference is irrelevant; on a tank with 40 metres of fillet seams or a landfill cell with dozens of pipe boots, it's the difference between finishing today and finishing tomorrow. If your welders run seams continuously, the EX3's output pays for its premium within the first big contract.
2. Melt Quality: Screw vs Barrel Extruder
The EX3's barrel extruder produces a particularly uniform, bubble-free melt at high output — a genuine advantage on consultant-inspected structural welds where every coupon gets peel-tested. The EX2's melt quality is fully professional too; the EX3 simply holds it at a higher flow rate.
3. Handling: Compactness vs Sustained Comfort
At 500mm and 6.4kg, the EX2 is the more agile machine — inside tank manways, between pipe runs, and in the awkward positions repair work creates, its shorter body and 360° rotating shoes with the extra side handle win. The EX3's ergonomic rotary handle is instead optimised for hours of continuous seam welding in one orientation — production comfort over confined-space agility.
4. What's Identical — and Why That's Good News
Wire (Ø3/Ø4mm HDPE and PP), the full PTFE welding shoe range, heating elements, scraper sets and carbon brushes are shared across both machines. A workshop running an EX2 and an EX3 stocks one spares shelf — one of the quiet reasons many UAE fabricators standardise on the Booster platform rather than mixing brands.
Which One for Which Job?
- Plastic fabrication workshop (tanks, containers, ducting): EX2 for general benches, EX3 on the production line.
- Geomembrane lining contractor: EX3 for the volume of detail welds on large cells; EX2 as the second machine for patch and repair crews. Both work alongside wedge machines like the WGW 300 that run the long seams.
- Maintenance and repair teams: EX2 — the jobs are short, varied and often in tight spots.
- Pipe fabrication: EX3 for long continuous joints; EX2 where fittings and awkward angles dominate.
Price and Availability in the UAE
Both machines sit inside the AED 12,500–14,500 bracket for professional hand extruders in the UAE — the EX2 opening it and the EX3 at the top — with kit versions including transport case, shoe kit, heating element and tools. (For how extruders compare against hot air and wedge machine costs, see our UAE welding machine price guide; for how the technology itself works, our extrusion welding explained guide covers the full process.)
We hold both models, plus wire, shoes and elements, in Dubai stock with 1–2 day delivery across the UAE. Call +971 50 178 9490 with your typical seam types and daily metreage — we'll tell you straight which Booster fits, or whether your work justifies both.
FAQs — Weldy EX2 vs EX3
What is the main difference between the Weldy EX2 and EX3?
Output. The EX3's barrel extruder delivers up to 3.4 kg/h of weld material versus the EX2's 2.5 kg/h — about 35% more — making the EX3 the production machine and the EX2 the more compact all-rounder. Power, wire sizes and weldable materials are identical.
Is the Weldy EX3 worth the extra cost over the EX2?
If you weld long seams daily, yes — the time saved per contract outweighs the price difference quickly. For mixed fabrication, repairs and occasional use, the EX2 delivers the same weld quality at lower cost.
Do the EX2 and EX3 use the same welding shoes and wire?
Yes — both take Ø3/Ø4mm HDPE and PP wire and the complete Weldy PTFE shoe range (V-weld, overlap, fillet, corner and blank shoes), so consumables are fully interchangeable between them.
What is the price of the Weldy EX2 and EX3 in the UAE?
Both fall within AED 12,500–14,500: the EX2 at the lower end of the bracket, the EX3 at the upper end, depending on kit configuration.
Which is the best Weldy extrusion welder?
There's no single answer: the EX3 is the best for output and continuous production welding; the EX2 is the best for versatility, confined spaces and mixed workshop duty. Match the machine to your dominant seam type.
Can I buy Weldy EX2 and EX3 spare parts in Dubai?
Yes — welding wire, shoes, heating elements, carbon brushes and scraper sets are held in local Dubai stock with UAE-wide delivery. Call +971 50 178 9490.
