The Weldy EX3 is a well-rounded handheld plastic welder, particularly suitable for professionals working with thermoplastics like HDPE, LDPE, LLDPE, and PP. With a power output of 3000W and an extruding volume of up to 3.4 kg/hr, it delivers efficient performance for tasks such as welding tanks, pipelines, and containers, making it a great choice for civil engineering, construction, and agriculture sectors.

One of its notable strengths is its ergonomic design, featuring three customizable handles that improve control and reduce strain during extended use. The ability to draw in welding rods from either side enhances its usability in cramped spaces. Additionally, it allows for welding thicknesses of 15-25 mm, catering to various project demands.

However, there are a few drawbacks to consider. The temperature control is open loop, which may limit precision for more sensitive welding applications. Weighing in at 6.9 kg, it could feel heavy for some users, especially during prolonged use. In terms of build quality, the durable construction is backed by a manufacturer warranty, reassuring users that they have support in case of issues. The tool box provided is also a plus, ensuring the welder is stored securely when not in use.

This makes it suitable for both beginners and professionals, though beginners might need some practice to get the heat settings just right.

One of its highlights is the wide range of included nozzle attachments and accessories, all neatly packed in a durable carrying case. The stainless steel nozzles resist heat and corrosion, promising long-term use without warping. The kit also includes handy tools like rollers and trimming knives, which help improve welding quality and finish. The built-in fan and automatic cooling system protect the heating element, extending the tool’s lifespan.

The welder’s build quality feels solid with a heat-resistant handle, reducing the risk of burns during use. However, it’s a bit on the heavy side (over 9 pounds with accessories), which might be tiring for extended handheld use. While airflow control isn’t specifically mentioned, the focus on precise temperature adjustment and nozzle variety helps maintain good welding control. This welder covers all the essential features you’d expect in a plastic welding kit and adds useful extras for various repair tasks. It’s well suited for those working in roofing, automotive repairs, or general plastic patching, offering good value for its price.

While the powerful output and temperature control options are great, some users may find the high temperatures intimidating, especially if they're new to plastic welding.
