PEMPure-water electrolysis technology
Oxyhydrogen Welding & Cutting Machine
Hydrogen and oxygen are generated from pure water and burn only at the torch tip. No gas cylinders, no high-pressure storage, no acetylene — just water, electricity and a clean flame.
- Pure water hydrogen generation
- No gas cylinders needed
- Plug and point
- Green and convenient
- 15000 L/HLargest model — containerised multi-torch system
- 0.2 MPaWorking gas pressure, stable at the torch
- 70%Up to this much lower running cost than acetylene
- 80 mmMaximum carbon-steel cutting thickness
Product introduction
What an oxyhydrogen welding machine actually is
FORWARD oxyhydrogen welding and cutting machines use state-of-the-art PEM pure-water electrolysis. Hydrogen and oxygen are generated in separate channels with two independent gas–liquid separators, and are mixed for combustion only at the torch tip. Different nozzles enable welding or cutting.
Fill the machine with pure water, switch it on and work immediately. Water vapour is the only by-product, so the unit replaces acetylene and liquefied gas for welding, sealing, flame polishing and cutting — clean, eco-friendly and easy to operate.
Traditional alkaline electrolysers mix hydrogen and oxygen inside the tank and use a concentrated alkaline electrolyte, which risks gas leakage and piping corrosion from alkaline mist. This machine uses pure water only, fundamentally removing both risks.
- Separate H₂ and O₂ channels, mixed only at the nozzle
- Pure-water electrolysis — no alkaline electrolyte, no corrosion
- Water vapour is the only combustion by-product
- Replaces acetylene and liquefied gas for welding, sealing and cutting
Key benefits
Five reasons workshops switch to oxyhydrogen
The same flame you know — produced on site, from water, without a cylinder in sight.
2
Eco-friendly with zero pollution
Pure-water electrolysis with zero emissions. Only water vapour leaves the torch.
3
Low cost and high efficiency
Running cost reduced by 40%–70% compared with an acetylene or propane flame.
4
High-quality welding
No carburising flame and brighter solder joints, with far less post-weld cleaning.
5
On-site welding or cutting
No gas station and no cylinders. Fill with water, switch on, start work.
Operating principle
From pure water to a welding flame
Three stages, all inside one cabinet: generation, separation, combustion at the tip.
1 · Pure water inFill the tank with pure water. No electrolyte, no chemical additive.
2 · AC 380 V powerA standard three-phase supply drives the PEM stack. Switch on and gas starts.
3 · PEM electrolyzerA proton-exchange-membrane stack splits water into hydrogen and oxygen inside separate channels.
4 · Two gas-liquid separatorsIndependent separators deliver dry H₂ and O₂ through their own pipelines.
5 · Multi-stage flame suppressionFlashback arrestors on both lines; the gases meet only at the torch nozzle.
H₂ and O₂ travel through two independent pipelines and are mixed only at the torch nozzle, so no explosive mixture is ever stored inside the machine.
