What Is a Hot Air Welding Machine?
A hot air welding machine — often called a hot air gun or heat gun machine — joins thermoplastic materials by blowing precisely temperature-controlled air onto the joint until the surfaces melt, then pressing them together with a nozzle or roller. Unlike a DIY heat gun from a hardware store, professional hot air welders hold their set temperature within a few degrees, run for full shifts without overheating, and accept speed nozzles, rollers and shoes for different welding jobs.
These tools are the everyday workhorses of roofing and waterproofing crews, geomembrane installers, plastic fabricators and industrial maintenance teams across the UAE and Africa — we cover the wider category in depth at our dedicated hot air hand tool resource site. This guide compares every Weldy hot air machine we supply, with current UAE price ranges and advice on which model fits your work.
Weldy Hot Air Gun Range Compared
Weldy HT1600 – Best Value Professional Hot Air Gun
The Weldy HT1600 is a 1600 W, 1.0 kg hand tool with variable temperature control up to 700°C, ceramic heating element and 240 l/min air volume. It handles plastic welding, roofing membranes, geomembrane detail work and cable shrinking — the one tool most crews buy first, and a firm favourite for its unbeatable value.
Weldy HT1600 D – Digital Control for QA Projects
The HT1600 D adds an LCD display, probe-controlled digital temperature (40–620°C) and memory settings to the same platform. Choose it when consultants require documented, reproducible weld parameters on lining or waterproofing projects.
Weldy HT3400 – High-Power Heating & Shrinking
With 3400 W output through a 50 mm nozzle at 320 l/min, the HT3400 is built for large-scale shrinking, bending, drying and workshop heating rather than seam welding — roughly double the heated air delivery of a standard gun.
IZ Series Hot Air Guns for HDPE Geomembrane
Our IZ line covers geomembrane-focused work: the IZ-1600 hot air gun for tack welding and liner repairs, and the IZ-3400 when higher heat output is needed on thick HDPE sheet.
Hot Air Gun Price in UAE
Professional hot air welding machine prices in the UAE typically run:
- 1600 W class (HT1600, IZ-1600): AED 800 – 1,800 depending on kit (bare tool vs overlap or plastic welding kit with roller and nozzles)
- Digital 1600 W class (HT1600 D): AED 1,500 – 2,500 with case and kit
- 3400 W class (HT3400, IZ-3400): AED 1,800 – 3,500 with accessory nozzles
Beware of AED 100–300 “heat gun machines” sold for paint stripping — they lack the temperature stability and duty cycle for welding and fail quickly under professional use. For full equipment budgeting alongside seam welders, see our price guide for UAE contractors.
Which Hot Air Welder Should You Choose?
- Roofing, waterproofing, general plastic welding: HT1600 with the overlap welding kit — best value, covers 90% of jobs.
- Consultant-supervised geomembrane or QA sites: HT1600 D — the digital readout proves welds were made at approved temperatures.
- Shrinking, bending, drying, workshop heating: HT3400 — power over precision.
- HDPE liner crews: IZ-1600 for daily detail work, IZ-3400 for thick sheet.
Remember that hot air tools handle tack welds, details and repairs — long production seams on liners belong to a wedge welding machine such as the WGW 300 or lightweight Miniwelder GEO2, while thick-section joints need an extrusion welder like the EX2. Our geomembrane welding machine guide explains how the three technologies work together.

Frequently Asked Questions
What is the difference between a heat gun and a hot air welding machine?
A basic heat gun blows hot air with loose temperature control for stripping or drying. A hot air welding machine holds its set temperature precisely, runs continuously, and accepts welding nozzles and rollers — essential for fusing plastics rather than just heating them.
What is the hot air gun price in UAE?
Professional 1600 W hot air guns cost AED 800–1,800, digital models AED 1,500–2,500, and 3400 W tools AED 1,800–3,500, depending on the kit and accessories included.
Which hot air gun is best for HDPE welding?
The Weldy HT1600 or IZ-1600 with a speed welding nozzle handles HDPE detail welding and repairs. For documented QA work choose the HT1600 D; production seams still need a hot wedge machine.
Can a hot air welding machine weld roofing membranes?
Yes — TPO, PVC and modified bitumen membranes are routinely hot air welded. A 1600 W gun with a 40 mm overlap nozzle and pressure roller is the standard roofing setup.
Are Weldy hot air tools good quality?
Weldy is the professional value line from the Leister Group of Switzerland — the same engineering house behind the industry’s reference-standard tools, built to genuine professional duty cycles at accessible prices.
Do you supply spare heating elements and nozzles?
Yes — ceramic heating elements, speed nozzles, overlap nozzles, rollers and carbon brushes are stocked for every model we sell, in the UAE and export markets.
