USED 1987 AIRCO 250 AMP TIG WELDER

Airco 250 Amp Heliwelder V Square Wave TIG/Stick WelderAC/DC Square Wave | High Frequency Start | 230/460V Single PhaseAvailable is a classic Airco Heliwelder V, the gold standard for heavy-duty transformer TIG welding. Known for its exceptional arc control and "bulletproof" reliability, this 250-amp machine features Square Wave technology, making it a favorite for high-quality aluminum and stainless steel fabrication. Unlike modern inverters, this transformer-based unit is built to last decades and can handle the rigors of a high-production shop environment. Ready for immediate use in any professional metal fab, automotive, or aerospace setting.Tech SpecsModel: Heliwelder V (250 Amp Series)Output Range: 2 to 250 Amps (AC/DC)Welding Processes: TIG (GTAW) and Stick (SMAW)Input Power: 208/230/460V, Single-Phase, 60HzDuty Cycle: 60% @ 250 AmpsTechnology: Square Wave Transformer (provides better arc stability on aluminum)Features: High-frequency arc starting, post-flow gas control, and remote amperage capability (pedal or torch control).Power Draw: High (Requires a minimum 60–100 Amp circuit for full output)Key Selling PointsSuperior Arc Stability: Square wave output provides a more stable AC arc for aluminum welding with less "puddling" and better penetration control.Heavy-Duty Duty Cycle: Rated at a 60% duty cycle at its full 250-amp output, allowing for long, continuous weld beads on thick plate.Versatile Power Input: Can be wired for 208V, 230V, or 460V single-phase power, fitting into almost any shop or industrial electrical service.Includes Gun & LeadsFoot PedalLegendary Durability: These "Made in the USA" transformers are famous for their longevity and ease of service, often outlasting several generations of newer inverter welders.
