Description
The Thermamax Pegasus 250 is a high-capacity, industrial-grade MMA (Manual Metal Arc) inverter designed for heavy-duty structural welding and large-scale fabrication. Engineered to deliver a massive 250A output from a single-phase supply, the Pegasus series is known for its “workhorse” reliability on South African job sites. Whether you are working with thick carbon steel plates or stainless steel alloys, this machine provides the penetration and arc stability required for X-ray quality welds.
Key Features:
- High-Amperage Industrial Output: Delivers a powerful 250A current, allowing for the continuous use of 4.0mm and 5.0mm electrodes.
- Advanced IGBT Inverter Design: Optimized for energy efficiency and a smooth, consistent DC arc that minimizes spatter and cleanup time.
- Superior Duty Cycle: Built for high-productivity environments, ensuring the machine stays cool during prolonged welding sessions on heavy-gauge materials.
- Adaptive Hot Start & Arc Force: “Hot Start” provides an immediate current boost for easy arc ignition, while “Arc Force” monitors the arc voltage to prevent the rod from sticking in the weld pool.
- Voltage Fluctuating Protection: Designed to handle the power variances often found when running off large generators or long extension leads on-site.
- Digital Current Meter: Features a bright digital display for precise amperage setting, essential for meeting strict welding procedure specifications (WPS).
Technical Specifications:
- Input Voltage: 230V ± 15% (Single Phase).
- Amperage Range: 20A – 250A (Adjustable).
- Duty Cycle: 60% at 250A (at 40°C).
- Electrode Capacity: 2.0mm to 5.0mm (E6013, E7018, Stainless Steel, and Cast Iron).
