The Orion 250s, our mid-range model with some extra power, boasting a power potential of up to 250 joules of pulse-arc weld energy. While powerful, the 250s is perfect for low power needs as well—yielding as little as 1 joules of energy. Even with such a large range in power, full control is maintained as the 250s is adjustable in o.2 joule increments. The 250s has two weld modes: Pulse Arc Mode and Tack Mode. Whether an application requires high power welding needs or intricate, precise welds around precious components, the Orion 250s offers a versatile, compact, and affordable welding system in an easy-to-use package.
