USED 1981 UNITEK 300-S1

1981 Unitek/Electro-Arc 300-S1 Tap DisintegratorSerial Number: 81289 | 360° Swivel Head | 60-Amp PowerDealer DescriptionThis 1981 build represents the peak of American-made industrial durability. The 300-S1 is highly sought after for its all-angle swivel head, which provides the flexibility to position the electrode at any angle—perfect for oversized castings or complex parts that cannot be easily secured to a standard table. Equipped with a 12-inch auto-servo stroke, the machine automatically maintains the ideal arc gap for consistent, efficient cutting. Unlike modern units with sensitive digital components, the analog controls on this 1981 model are famous for their longevity and ease of maintenance in demanding shop environments.Technical SpecificationsYear of Manufacture: 1981Head Style: 360° Swivel with 15" horizontal adjustmentQuill Stroke: 12" Servo-controlledDisintegration Capacity: #0-80 to 3/4" (0.020" to 0.750")Power Output: 60 Amps (Variable control)Electricals: 120V / Single Phase / 60HzWork Table: Precision 30" x 30" T-slotted surfaceWeight: Approximately 600 lbs (Mounted on heavy-duty casters)Dealer Note: This unit is a "profit-protector."
