Electrofusion welding machines are available in various models depending on the material, diameter, and application of the pipes being welded. For example, the K & F series electrofusion welding machines offer flexible welding options, covering pipe diameters from 20mm to 1000mm.
The HTDC-10BN electrofusion welding machine is specifically designed for electrofusion welding of Dn50-400 steel-reinforced plastic composite pipe fittings. This model features microcomputer control, a backlit LCD display, and functions such as soft-start and fault protection alarms. Its technical parameters include: input voltage AC380V±20%, input power 10KVA, output voltage DC3～130V, output current 45A, operating environment -15～40℃, and weight 45 kg.
The WP20F and WP35F are two portable electrofusion welding machines suitable for connecting polyethylene (PE) and polypropylene (PP) pipes. The WP20F has a welding range of 20-200mm, a power of 2.5 kW, and a weight of 18.5 kg; the WP35F has a welding range of 20-315mm, a power of 3.5 kW, and a weight of 20 kg. Both models support automatic and manual welding modes, have built-in voltage regulators, and feature overload protection.
