Dera PPR PVC welder 800W

A Dera PPR PVC welder with an 800W power rating is a specialized tool used for joining plastic pipes and fittings, typically in plumbing, heating, and industrial applications. This type of welder is specifically designed for socket fusion welding, a process that creates a permanent, leak-proof bond between plastic pipes.

How it Works

The process is straightforward:

1. Heating: The tool has a heating plate with holes for male and female dies. The male die is for the inside of the pipe, and the female die is for the outside of the fitting.
2. Melting: The welder heats the surfaces of both the pipe and the fitting to their melting point (around 260°C for PPR).
3. Joining: Once the plastic is molten, the pipe is quickly and carefully inserted into the fitting.
4. Fusion: The melted plastic from both parts fuses together, creating a single, continuous, and highly durable joint as it cools.

Key Specifications and Features

• Power (800W): The 800-watt power rating indicates a fast heating time and the ability to maintain a consistent temperature during welding. This is a standard power level for welders of this type and is sufficient for typical plumbing work.
• Heating Plate and Dies: The welder comes with a heating plate and a set of interchangeable dies. Common sizes are 20mm, 25mm, and 32mm, but some kits include larger sizes up to 63mm. These dies are coated with a non-stick material, often Teflon, to prevent the plastic from sticking.
