Fabrication Kits
Fabrication Kits
Who buys a fabrication kit?
Fabrication kits are the everyday workhorse — the right choice for workshops, jobbing fabricators, plumbers, apprentices, and anyone doing mixed plastic welding work across multiple materials.
Workshop fabricators
Tank construction, ducting repair, plastic component fabrication, one-off plastic parts. The mixed-rod selection means you're ready for whatever plastic walks in the door.
Plumbers and tradespeople
PVC pipe repair, HDPE pipe joins, water tank work, polypropylene drainage. The kit covers the common plumbing plastics without needing a separate setup for each.
Training and apprentices
Learning hot-air plastic welding properly. A fabrication kit puts the trainee on the same kit they'll use in production work, so the skills transfer directly.
What's typically in a fabrication kit
| Component | Purpose |
|---|---|
| Hot-air welder | The core tool. Usually a Techspan Rion or Triac with digital temperature control. |
| Speed nozzle (round, 4mm) | Feeds the welding rod and directs hot air onto the joint in a single integrated profile. |
| Welding rod selection | 3mm and 4mm round rod in PP, PE-HD, PVC, ABS and PEMD. Match rod to plastic being welded. |
| Pressure roller (silicone) | Compresses the molten weld bead evenly without sticking. Brings the rod into full contact with the substrate. |
| Brass brush | Cleans the joint surface before welding and removes oxidation from the rod. Small detail, big difference to weld quality. |
| Carry case | Keeps the kit organised and protects the welder in transit. Fits in a van or under a workshop bench. |
When a fabrication kit isn't the right choice
- Production roofing membrane work — use a roofing kit with the higher-output welder and membrane-specific nozzle.
- Daily automotive bumper repair — an automotive kit is configured for PEMD specifically.
- Continuous structural welding of thick HDPE — step up to an extruder welder for wall sections over 6mm.
- Long seams on tarpaulin or membrane — an automatic overlap or wedge welder will produce more consistent seams faster.
First time welding plastic?
Read our step-by-step hot-air welding guide before starting, and check how to identify the plastic you're welding. Getting the rod-to-substrate match right is the difference between a structural weld and one that fails.

Frequently asked questions
What's in a typical fabrication kit?
A general-purpose hot-air welder (typically the Techspan Rion or Triac), a selection of welding rods covering the most common plastics (PP, PE-HD, PVC, ABS), the matching speed nozzles for round rod, a pressure roller, brass brush and a sturdy carry case. The exact specification varies by kit, so check the product listing.
Can a fabrication kit handle automotive bumper repair?
It can, but a dedicated automotive kit is better. Fabrication kits include a broader rod selection across multiple plastics; automotive kits are configured specifically with PEMD rod (what modern bumpers are made of) and the right speed nozzle and roller for curved surfaces. If you're doing one bumper repair amongst other workshop welding, fabrication will cover you. If you're doing bumpers regularly, choose the automotive kit.
What plastics will a fabrication kit weld?
All the common thermoplastics: polypropylene (PP), polyethylene (HDPE and PEMD), PVC, ABS, and PP/EPDM blends. The kit includes the matching rods, so you have what you need for whichever plastic the job calls for. Welding rod identification still matters — match rod to substrate every time.
How heavy-duty is the welder in a fabrication kit?
Most fabrication kits use the Techspan Rion (around 1600 W) or Triac (1600-1700 W). Both are commercial-grade tools with duty cycles suited to daily workshop use. For continuous structural welding of thick HDPE tanks or long industrial seams, step up to the Triac S or pair the welder with an extruder welder.
Is a fabrication kit a good choice for an apprentice or trainee?
Yes — fabrication kits are the right starting point for learning plastic welding properly. The welder, rod and accessories are all matched so the trainee learns on the right setup, and exposure to multiple plastics builds the fundamentals that transfer to specialised work later. See our step-by-step welding guide for the technique.
