8 Recommendations for Electro Arc Machine and Operator Safety

Your Electro arc Machine is durably built, thoroughly tested, and inspected at the factory. You can expect many years of service with minimal maintenance. To maintain the accuracy, dependability, and cutting speed built into your metal disintegrator, please heed these warnings and recommendations for machine and operator safety.

Warnings: When connecting your machine to power – The Installer and Electrician must confirm that a solid ground exists between the cabinet and the building ground.

NEVER CHANGE THE HEAT SETTING IN THE MIDDLE OF A CUT WITH AUTO FEED ON. THIS WILL SHORT OUT THE AUTO-FEED CIRCUIT BOARD

Recommendations for operator safety when operating your Electro Arc metal disintegrator:

  1. Use a splash bag or shop towel to control coolant splashing before starting the machine.

2. Avoid touching the operating head and workpiece/table at the same time while operating the machine.

3. Fasten your workpiece securely to avoid “walk” which can damage the threads in the hole.

Disintegration works on the principle of a vibrating spindle with an electric power supply creating a series of intermittent arcs. AC machines make and break 60 arcs per second and DC machines make and break 120 arcs per second to disintegrate the hardest metals. The particles created during the disintegration process are flushed away by coolant flowing through the center of the electrode.
DO NOT USE SYNTHETIC COOLANTS.

4. Always refer to the electrode chart for Electrode sizing. Electrodes from .025 to .060 diameter draw very little amperage and will show little change on the current indicator.
Select an electrode that will only remove the center core of the tap. This will remove the core of the tap and leave the flutes standing in the threaded section. These may be blasted out with air or removed with a magnetic pick set. You will be left with a perfect threaded hole.

5. When you are removing broken drills, snap off the flutes after every two inches of cutting travel. This may be done quite easily using the same size drill and rotating it in the hole.

6. Removing Hardened Screws and Studs:
You need to select an electrode approximately .020 under the minor diameter of the thread. For a clean-cut, collapse the wall of the screw – remove the particles and retap. This will clean out the male threads without damage to the female threaded section. You may also choose to disintegrate a square or hex in the stud and turn it out with the proper size tool.
Caution: Always make sure your electrode is straight.

7. Replace the coolant frequently – Clean the tank every 4-6 hours of operation. The metal disintegration process creates abrasive particles which can shorten the pump life.

8. Please consult with Electro Arc if your machine is in need of repair.  If your machine is under warranty, do not attempt to make repairs prior to contacting our facility as it will void your warranty, additionally always consult with your operators manual for electrical diagrams, troubleshooting steps and part numbers.
