Weldy Extrusion Welder Range Explained: EX2, Booster EX2 & EX3
Buyers researching a Weldy extrusion welder quickly meet several model names — EX2, Booster EX2, Booster EX3 — and it is not obvious how the family fits together. As the team that stocks the Weldy Booster EX3 in Dubai, here is the plain-language map of the Weldy extruder range and how to choose within it.
How the Weldy hand extruder family is organised
All Weldy hand extruders share the same working principle — welding rod fed into a heated barrel, melted, and extruded through a PTFE shoe with hot-air preheat — and differ mainly in output rate, size and ergonomics:
- Weldy EX2 / Booster EX2 — the compact end of the range: lighter units built for detail work, repairs and fabrication where access is tight and output demands are moderate.
- Weldy Booster EX3 — the mid-range workhorse we stock: 3000 W, up to 3.4 kg/h on Ø3–Ø4 mm rod, built for standing operation in plastics plants, tanks, tunnels, pipe construction and landfill sites, welding HD-PE, LD-PE, LLD-PE and PP.
- Larger Weldy extruders exist above the EX3 for maximum-output fabrication; they are special-order items in our region.
Why we standardised on the EX3 for Gulf and African projects
- Output vs weight balance — 3.4 kg/h covers geomembrane details, tank fabrication and pipe work, at 6.9 kg an operator can run all shift.
- Rod flexibility — Ø3 and Ø4 mm in one machine matches the rod we stock (including 4 mm IZ-4MM-WELD grades).
- Serviceability — shoes, heating element and brushes are kit items we hold in Dubai (see the parts guide).
Need the compact EX2 class instead, or a higher-output unit? We can source across the Weldy range on request — tell us your materials, wall thicknesses and daily welding hours and we will recommend honestly, including when our value-line IZ-620 is the smarter buy for occasional use.
Choosing in one minute
