ESAB · Stick Welding (SMAW / MMA)
The ESAB Origo Arc 455 is an industrial direct-current welding rectifier for manual metal arc welding with a wide range of coated electrodes, delivering 400 A at 36 V on a 35% duty cycle and 230 A at 30 V continuously from a 380 V 50 Hz three-phase supply, with a 79–80 V open circuit voltage for easy striking.

Where it is used
Features
80 V open circuit on the 60 Hz supply, 79 V on 50 Hz. A high OCV makes the arc easy to strike and keeps it stable, which is what suits this machine to difficult electrodes and to welders of mixed experience. Note the trade-off: a high OCV machine is not one for confined-space work where VRD would be required.
Rated for carbon and alloyed steel, stainless steel, cast iron, aluminium and its alloys, copper and bronze. Cast iron and bronze in particular need a stable low-current DC arc, and few machines in this class name them.
Welding current is set by a crank on the front panel, allowing precise selection for the application. There is no menu, no digital panel and nothing to misconfigure — which on a shared shop machine is a genuine advantage.
Operates on 220, 380 or 440 V at 60 Hz, or 380 V at 50 Hz. Output differs between the two frequency bands and both sets of figures are published on this page.
A powerful cooling fan protects the internal components against excess temperature, which is what underpins the 230 A at 100% duty cycle rating.
A compact robust cabinet built in galvanised sheet and finished by an electrostatic antioxidant process — the right specification for a humid coastal environment.
Welding cables connect by OKC terminal, which improves safety in the welding area compared with exposed bolted connections.

Frequently asked
400 A at 36 V on a 35% duty cycle, 300 A at 32 V at 60%, and 230 A at 30 V continuously at 100%, from 380 V 50 Hz. The headline 450 A figure applies only on a 60 Hz supply, so the 50 Hz column is the one to quote against in the UAE.
Carbon and alloyed steel, stainless steel, cast iron, aluminium and its alloys, copper and bronze. That is a wider list than most machines in this class publish, and it follows from the high open circuit voltage and stable DC output.
It makes the arc easy to strike and keeps it stable, which helps with difficult electrodes and with less experienced welders. The trade-off is that a machine with 79–80 V OCV and no VRD is not suitable for confined-space or wet work where reduced voltage is required.
No — it is a transformer-based welding rectifier. That means it is heavier (125 kg) and less efficient than an inverter, but with far fewer electronics to fail. For a shop that wants a machine that simply works for twenty years, that is often the point.
By a single crank on the front panel, which allows precise selection of the parameter for the application. There is no digital panel and nothing to misconfigure.
Three-phase at 220, 380 or 440 V on 60 Hz, or 380 V on 50 Hz. Fuse requirements differ: 80 A at 220 V, 50 A at 380 V and 40 A at 440 V.
