Electro Arc Metal Disintegrators made in Michigan since 1947

Electro Arc is the original manufacturer of Metal Disintegrators based in Michigan.  The company’s founder, Harold Stark patented the AC metal disintegration process in 1942 and opened Electro Arc’s doors in 1947.  Stillion Industries purchased Electro Arc in 2019 and carries on the quality name that Electro Arc metal disintegrators have become synonymous with.

Electro Arc Metal Disintegrators Last a Lifetime

You can see one of Electro Arc’s original paper promotions above, featuring the following models: 

Model 2-S – Still one of our most popular portable models!  This basic metal disintegrator now features our Arc-er Head and portable design which make it perfect for use in small shops.

1-S (See below) – The model 1-S was the largest table top metal disintegrator offered by Electro Arc initially.  

2-SA – The model 2-SA was one of the first tabletop metal disintegrators offered by Electro Arc.  This self-contained unit is great for high production plants and tool shops.

3-S – The model 3-S originally offered with no built-in coolant tank offers great portability for use in confined spaces.

Not shown on this flyer, the Carbide Impregnator was another flagship product Electro Arc was known for between the 1940s and 1970s.  Electro Arc is the original and best manufacturer of metal disintegrators in the world.  Our machines are known for their durability and long-lasting design.  Now among over 40 configurations available, we are confident you will find an Electro Arc metal disintegrator is still the best value for your application!

Over 75 Years of Michigan Manufacturing

As you can see, the original disintegrating head is different than our current Arc-er, IQ, and Servo disintegrating heads.  The features of Electro Arc metal disintegrators are the same great features allowing anyone to use our machines.  Electro Arc Metal Disintegrators have castors, the choice of AC or DC, and portable or tabletop, including the option to order a custom table top size.  Most models allow you to choose your KVA power rating.  Additional features include support options, head options, remote start/stop, and more!

In 2004, Electro Arc purchased Uni-Tek and integrated DC metal disintegrators into our product line.  Our most powerful machine, the Bolt Eater represents the heavy-duty application of metal disintegration with both portability and the power to remove large bolts!

Stillion Industries is proud to carry on the Electro Arc Metal Disintegrator legacy in Dexter Michigan! We continue to improve the metal disintegrator design and offer repair and refurbishing services for old machines. Learn more about Electro Arc’s history.

5 Steps to Choose the Machine You Need to Remove Broken Bolts

Remove broken bolts with your Electro Arc Metal Disintegrator

Our broken bolt, drill, and tap removal technology is the most cost-effective and precise method available in the market.  Patented in 1942, AC metal disintegrators were made and distributed exclusively by Electro Arc for years before competitors entered the market.  Electro Arc purchased Uni-Tek in 2004 and began making and distributing DC machines as well including the Bolt Eater.  Electro Arc metal disintegration machines have been built in Michigan since the company began in 1947.  These machines are known for their long-lasting design and easy-to-use configuration, allowing companies to apply the technology across industries.

You can use Electro Arc metal disintegration machines to quickly and easily remove the broken-off tap, drill, and or bolt without damaging your valuable equipment. In the infographic above, you can see the details of our precise spark erosion process.  Please refer to the following recommendations to choose the right metal disintegrator for your needs.

How to choose the right metal disintegrator for your application:

Step 1. Do you need an AC or DC power supply? 

Both AC and DC machines run 110 to 600 volts to vibrate AC machines make and break 50 or 60 times per second, while DC machines are at 120 times per second.  DC power can maintain higher arc levels and sustain a larger arc.  With DC machines you can use larger electrodes like square or hex-shaped carbon to drill faster and make larger holes.

Step 2. Next, which disintegrating head do you need? IQ, Servo, or Arc-er.

You can use the Arc-er head with our portable metal disintegrators and you can use it directly with machines like a Bridgeport. The IQ head provides faster-cutting speed and can be used with larger electrodes.  You will receive a Servo head with our DC machines.

Step 3. Do you want a Portable or Table top machine?

Portable machines are great for on-site application.  If you need to take the metal disintegrator to the part, a portable metal disintegrator is for you.  Off-road vehicle repair, mining operations, submarines, and repairs on the line are some great examples that would benefit from a portable machine.

You will want a tabletop machine if you are working on parts that can be taken to the machine for disintegration.  We offer tabletops ranging in sizes and can create custom table tops if needed.

Step 4.

Which electrode do you need? 

We offer electrodes made of graphite, copper, and molybdenum.  Depending on the hardness of your piece, you will want to choose the appropriate electrode.  Please refer to our sizing charts to choose the best one for your needs. 

Step 5. What kind of material are you working with?  

If you are working with carbide, you will want to choose a machine with “C” in the model number such as our 2-SEC which is a more compact tabletop machine offering the durability and power to disintegrate carbide.
