Welder specifications
FH-OH series — full specification table
All models run on AC 380 V and deliver gas at 0.2 MPa.
| Model | Gas flow rate | Gas pressure | Power supply | Dimensions | Nozzle quantity |
|---|---|---|---|---|---|
| FH-OH-1500 | 1500 L/H | 0.2 MPa | AC 380 V | 1045 × 710 × 1025 mm | 1 |
| FH-OH-4500 | 4500 L/H | 0.2 MPa | AC 380 V | 1045 × 710 × 1025 mm | 1–2 |
| FH-OH-9000 | 9000 L/H | 0.2 MPa | AC 380 V | 1200 × 1050 × 1525 mm | 1–4 |
| FH-OH-15000 | 15000 L/H | 0.2 MPa | AC 380 V | 3000 × 1750 × 1800 mm | 1–5 |
Gas flow rates are given at standard conditions; dimensions are for the standard cart-mounted cabinet. Optional: dual welding gun, automatic ignition module.
Cutting machine
Welder and cutter — the same cabinet, another nozzle
The oxyhydrogen welding and cutting machine is used interchangeably. By replacing the nozzle and connecting the machine to an oxygen tank, a welder is converted to a cutter: the oxyhydrogen flame preheats the steel and the high-pressure oxygen jet does the cutting.
Nothing else changes — no compressor and no second gas generator. The preheating gas is still made from water inside the cabinet.
- One cabinet for welding, brazing, polishing and cutting
- Connect a standard oxygen cylinder to switch to cutting
- Preheating and high-pressure cutting oxygen are separated
Cutting capability
Carbon-steel cutting thickness by model
| Model | Gas flow rate | Typical applications | Cutting thickness (carbon steel) |
|---|---|---|---|
| OH1500 | 1500 L/H | A popular industrial model, the main machine for steel plate cutting. | 15–25 mm |
| OH4500 | 4500 L/H | High-power industrial cutting for thick plates. | 25–40 mm |
| OH9000 | 9000 L/H | Heavy-duty thick plate work — a CNC cutting companion. | 40–80 mm |
Cutting requires a standard oxygen cylinder for the cutting-oxygen line — the preheating flame is produced by the machine from water.
Nozzles
A small orifice to weld, a ring of orifices to cut
The nozzle is the only thing that has to change between welding and cutting.
Welding nozzle
Small orifices produce a concentrated flame for fusion welding, brazing and flame polishing.
Cutting nozzle
A large central orifice surrounded by preheating orifices. Preheating and high-pressure cutting oxygen are separated for metal cutting.
