Leister extrusion welding kit

Step 1: Choose a Leister extrusion welder

Leister FUSION 2 extrusion welder

Leister FUSION 2 extrusion welder

The FUSION 2 is a high performance extruder for general fabrication and repairs. Its short length and moderate output rate make it useful for smaller spigot welding, tank repairs, container construction and more.

Features at a glance:
230V / 2800W
1.3-1.8kg/hr extrudate output rate
Uses 4mm profile PE and PP weld rod
450mm long, 5.9kg weight
Single heat zone, steplessly adjustable

Leister FUSION 3C extrusion welder

Leister FUSION 3C extrusion welder

The FUSION 3C has a very impressive output capability given its size and weight. The longer barrel and larger output makes the FUSION 3C ideally suited to geomembrane liner welding or for long continuous welds where the extra speed is very valuable.

Features at a glance:
230V / 2800W
2.7-3.5kg/hr extrudate output rate (4mm PE)
Uses 3mm or 4mm profile PE and PP weld rod
588mm long, 6.9kg weight
Single heat zone, steplessly adjustable

Leister WELDPLAST S2 extrusion welder

Leister WELDPLAST S2 extrusion welder

The WELDPLAST S2 is Leister's flagship extruder. It features a highly versatile material output, making it adaptable to a wide variety of welding applications both in the workshop and on-site. Ultimate control is achieved through separate heat settings for air and material, managed by a touchscreen digital interface.

Features at a glance:
230V / 3000W
0.6-2.3kg/hr extrudate output rate (PE)
Uses 3mm or 4mm profile PE and PP weld rod
450mm long, 5.8kg weight
Digital display and control of settings (+ in-built presets)
Dual heat zones (pre-heat & extrudate), steplessly adjustable

Step 2: Choose welding shoes

Leister's welding shoe range can be daunting at first but is easy to understand once you realise that each welding-grade Teflon block is shaped to generate a specific weld seam shape and size. Choosing the right shoe is based upon determining what shape weld you require, and matching the size to the output capability of the extrusion welder being used. Browse a selection of shoes below or download a welding shoe chart for FUSION and WELDPLAST models.

Step 4: Fit all of your new equipment into a purpose-built steel transport case

The steel cases have been designed by Polyweld Machinery specifically for the extruder models and tools listed above. There is a hidden shelf under the extruder to store welding shoes and hand tools, and brackets to hold the extrusion welder, the hot air tool, and a grinder with flap disc (for weld preparation) securely in place. Having all of the tools and accessories in one place helps you to safely manage your assets to, from and on-site.
