Electro-Arc 300-S1 Tap Burner - Swivel Head - Broken Bolt/Tap Remover - 120V

1981 Unitek/Electro-Arc 300-S1 Tap Disintegrator

Serial Number: 81289 | 360° Swivel Head | 60-Amp Power

Dealer Description

This 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.
