Weldy Booster EX3 Hand Extrusion Welder 3000W | 3.4 kg/h High-Output HDPE & PP Welding | Dubai UAE
Production-Grade Extrusion Welding for Heavy Fabrication in the UAE
On a big HDPE job, weld output per hour is money. A storage tank with metres of fillet seams, a landfill cell with dozens of pipe boots, a fleet of chemical containers on a production schedule — the machine that lays down more material per hour finishes the contract sooner. The Weldy Booster EX3 exists for exactly this class of work: a high-quality barrel extruder delivering up to 3.4 kg/h of homogeneous weld output, roughly a third more than its compact sibling, while staying light enough at 6.9 kg (15.2 lbs) for real hand-held site welding.
The EX3 plays to its strengths in plastics plants, tank farms and underground engineering across Dubai, Sharjah and Abu Dhabi. It welds all common polyolefins — HD-PE, LD-PE, LLD-PE and PP — with Ø3 or Ø4 mm wire, and its ergonomic rotary handle lets operators keep the shoe seated correctly through long, continuous seams that would exhaust them on a heavier machine. For teams that treat extrusion welding as daily production rather than occasional repair, this is the flagship hand extruder in our Weldy range.
Key Features of the Weldy Booster EX3
High-Quality Barrel Extruder — Up to 3.4 kg/h
The heart of the EX3 is its barrel extruder design, which plasticises welding wire into a uniform, bubble-free melt and pushes it out at up to 3.4 kg per hour. Consistent melt quality is what separates a weld that passes spark and peel testing from one that fails — and it is the reason fabricators specify barrel extruders for structural, consultant-inspected work.
Ergonomic Rotary Handle
Long seams mean changing body positions constantly. The EX3’s rotary handle turns so the operator’s wrist stays neutral whether the joint runs vertical, horizontal or overhead — inside a tank in Mussafah or along a berm on a Northern Emirates landfill. Less fatigue at hour six means better welds at hour six.
Genuinely Portable at 6.9 kg
Despite its output class, the EX3 weighs just 6.9 kg. Crews carry it up scaffolds, into excavations and through manways without rigging — a practical advantage over bulkier production extruders that never leave the workshop floor.
Easy to Operate
Weldy designed the EX3 to be learned fast: straightforward controls, visible melt flow, and predictable handling. In a market like the UAE where site crews rotate frequently, a machine new welders master quickly protects both schedule and seam quality.
Complete Kit in a Transport Case
The kit version arrives ready for site: rigid transport case, T-handle hex socket wrench, spare carbon brush for the drive motor, ULB30/15 welding shoe kit, heating element and brass cleaning brush. The full Weldy shoe range fits — V-weld (V8/10-X15/20, V12-X25, V15-X30), overlap (ULB25/30/35), fillet (KB/10, K15), corner and hose-corner shoes, plus blank kits for custom joint profiles.
Booster EX3 vs Booster EX2 — Output, Duty and Price Point
- Booster EX3 (this page): up to 3.4 kg/h, 6.9 kg, 630 mm length, barrel extruder — the production choice for continuous heavy welding on tanks, containers, pipes and landfill details.
- Booster EX2: up to 2.5 kg/h, 6.4 kg, 500 mm — more compact and agile for mixed fabrication, maintenance and repair duties; see the full Weldy Booster EX2 hand extruder page.
Both run 3000W on 230V, share the same wire sizes, materials and welding shoe ecosystem, and share consumables — so many UAE fabrication shops run an EX3 on production seams and an EX2 on repair and detail work with one common spares shelf.
Applications Across Dubai, Sharjah and Abu Dhabi
- Tank and container construction – chemical tanks, water tanks, electroplating baths
- Pipe constructions – large-scale HDPE pipe joints, fittings and fabricated manifolds
- Landfill sites and geomembranes – structural details, anchor trenches, penetrations and repairs on liners seamed with the WGW 300 hot wedge welding machine or the Miniwelder Geo2 geomembrane welder
- Sewage systems and water infrastructure – treatment plant internals, sumps, manholes
- Aquaculture and leisure infrastructure – fish farming tanks, pools and water attractions
- Maritime, vehicle and laboratory construction – ducting, benching, custom enclosures
- Plastic repairs – structural crack repair on PE/PP components and equipment
Around the extruder, complete your toolkit with hot-air units — the Weldy HT1600 hot air gun for tacking and detail, the digital HT1600 D for certified membrane seams, and the 3400W HT3400 for pre-heating and large-area work — plus thin-film machines like the Miniwelder Tex2 where membranes drop below 1 mm.

Frequently Asked Questions – Weldy Booster EX3
What is the output of the Weldy Booster EX3?
Up to 3.4 kg of weld material per hour from its 3000W barrel extruder — about 35% more than the Booster EX2, which is the meaningful difference on production seams.
What materials does the EX3 weld?
All common polyolefins: HD-PE, LD-PE, LLD-PE and PP, using Ø3 or Ø4 mm welding wire matched to the parent material.
Is the EX3 suitable for geomembrane and landfill work?
Yes — geomembrane detailing is one of its listed core applications. It handles pipe penetrations, anchor details, patches and structural repairs alongside automatic seamers like the WGW 300.
EX3 or EX2 — which should I buy?
Choose the EX3 for continuous, production-volume welding where 3.4 kg/h saves hours daily; choose the more compact EX2 for mixed fabrication, maintenance and repair. Many shops run both since they share wire, shoes and consumables.
How heavy is the Booster EX3?
6.9 kg (15.2 lbs) — light for its output class, and balanced by the rotary handle for vertical and overhead seams.
What welding shoes come with the EX3 kit?
The kit includes the ULB30/15 welding shoe kit; the complete Weldy shoe range (V-weld, overlap, fillet, corner, hose corner, blank) fits and is available from our Dubai stock.
Do you deliver the EX3 to Sharjah, Abu Dhabi and other emirates?
Yes — UAE-wide delivery, typically within 1–2 working days. Call +971 50 178 9490 to confirm kit version, wire and shoe availability.
