Which Weldy Machine Do You Need? Complete Range Selection Guide
Weldy builds hand extruders, wedge welders and hot-air tools, and each family has several models. This guide maps the full range we stock in Dubai so you can shortlist in minutes — every model links to its page and downloadable datasheet in our technical library.
Step 1: What are you welding?
- Long geomembrane panel seams → a wedge welder (WGW 300, Miniwelder Geo2)
- Thick structural joints, patches, tanks, pipes → a hand extruder (Booster EX3, Booster EX2)
- Thin films, roofing, tarpaulin seams → Miniwelder Tex2 / Tex1 or a hot-air tool
- Details, tacking, shrinking, drying → a hot-air hand tool (HT1600, HT1600 D, HT3400)
Step 2: Hand extruders — EX3 or EX2?
Both run Ø3–4 mm wire on HD-PE, LD-PE, LLD-PE and PP at 3000 W. The Booster EX3 delivers 3.4 kg/h for higher-output production welding; the Booster EX2 delivers 2.5 kg/h in a shorter 500 mm body with double-sided wire feed and 360° rotating welding shoes — better in tight, overhead and awkward positions.
Step 3: Wedge welders — by liner thickness
- 0.05–1.0 mm films → Miniwelder Tex1, ball wedge, 300 W, 15 mm seam
- 0.1–1.0 mm membranes → Miniwelder Tex2, 20 mm seam, 800 W
- 0.4–1.5 mm geomembrane → Miniwelder Geo2, 2×12 mm dual-track with test channel, 3.9 kg
- 0.8–2.5 mm HD-PE (to 3.0 mm LD-PE/TPO/PVC) → WGW 300, 1750 W, up to 8.5 m/min
Note the QA implication: the Geo2 and WGW 300 produce dual-track seams with an air test channel, which CQA-supervised landfill and pond projects require. The Tex machines produce single-track seams suited to roofing, films and covers.
Step 4: Hot air tools — by task
- HT1600 — 1600 W, 40–700°C, 240 l/min: the everyday welding tool for membranes, tarpaulin and details.
- HT1600 D — same power with digital control, LCD, probe feedback and memory settings: for reproducible, process-documented welding.
- HT3400 — 3400 W, 320 l/min, Ø50 mm nozzle seat: large-scale shrinking, bending, heating and drying rather than seam welding.
Typical kits we quote
