Electro Arc Model 2-S Metal Disintegrator 18 KVA 480V Power Feed Tap Burner

Electro Arc 18 KVA Portable Tap Disintegrator | Model 2-S | Power Feed

The Electro Arc Model 2-S is a heavy-duty, portable metal disintegrator designed for the precision removal of broken taps, drills, and studs. Known as the "workhorse" of the industry, the 2-S allows for the non-contact extraction of hardened tools without damaging the parent metal or original threads.

This specific unit (S/N 2037) is equipped with a swiveling head and automatic power feed, allowing for angled disintegration and hands-free operation. Featuring the high-capacity 18 KVA / 480V power supply, this machine is capable of handling larger tool removals that would stall smaller units. Mounted on heavy-duty casters with an integrated coolant system, the Model 2-S is the ultimate "part saver" for any high-volume machine shop or heavy equipment repair facility.

Key Features

• Swiveling Head Assembly: Enables the head to be positioned at any angle, allowing for the extraction of broken tools in workpieces that cannot be squared up vertically.
• Automatic Power Feed: Reduces operator fatigue and improves electrode life by maintaining a precise, consistent arc gap throughout the disintegration process.
• 18 KVA Transformer: Provides the high-amperage current necessary to burn through large diameter bolts and carbide drills quickly.
• Portable C-Frame Design: Heavy-duty casters allow the entire unit to be rolled directly to large workpieces, or the head can be removed for use on oversized castings.
• Non-Destructive EDM Process: Uses high-frequency spark erosion to remove the core of the tool, leaving the workpiece threads completely intact and the metallurgy unaffected.
