The coolant system is essential to the metal disintegrating process. Your metal disintegrator heats the electrode to 5000 degrees in order to disintegrate the metal, the coolant cools this temperature down so that no damage occurs to the electrode or part during the process. It also prevents the machine from overheating. It is important to run clean coolant through the machine, dirty coolant contains tiny metal particles which can cause permanent damage to your machine if dirty coolant is used.
Electro Arc makes the special S.P.C water primer coolant solution for metal disintegrators. This solution is good for a year, so if you haven’t used it or if you notice it has turned from its milky white color or has begun separating, please don’t use it in your machine. It is also important to change your coolant often, pay attention to the color of the coolant and be sure to change it every six hours of disintegration time. As mentioned earlier, running your metal disintegrator with dirty coolant can cause permanent damage to your machine. Remember, never store your metal disintegrator with coolant in it for an extended period of time as this will cause damage to the pump and require replacement of the pump and motor.
You can purchase Electro Arc SPC Water Primer and a replacement pump and motor directly from Stillion Industries’ Website. We sell full cases of coolant containing 12 bottles of the concentrated solution or half cases containing 6 bottles. This concentrate solution is a 20-1 concentrate. To get started using the coolant, mix one bottle with 5 gallons of water, shake up the bottle before mixing. Change the coolant once a week. Be sure to drain your coolant tank before refilling. Depending on the job you are performing, you may choose to collect the coolant and reuse it.
If you take advantage of the coolant recovery system, you can re-use your coolant. In this case, your coolant tank is also the recovery tank. Coolant is pumped at 90 PSI and delivered to your disintegrating head. The coolant recovery system contains a vacuum that will recover coolant in the work area. This method can be used in 3 applications:
Method #1 (Working on the table)
The vacuum hose is connected to the drain hose out the back of the table. With the workpiece on the table, the coolant falls to the table and drains to the back of the table and out the drain hose fitting. The vacuum sucks the coolant back to the coolant tank.
Method #2 (Working off the table)
With the disintegrating fixture on the table, the disintegrating head can be positioned off the side or back of the machine on to a large part. The vacuum nozzle is positioned at the point of disintegration to vacuum up the coolant.
Method #3 (Working remote in a portable application)
Coolant is pumped from the tank to the point of disintegration. The vacuum nozzle is positioned at this point and immediately vacuumed up and returned to the tank.
This closed-loop system works extremely well for working on large parts when the part can not be brought to the table. The system was designed to help keep your work area clean and dry. Machines with a dual coolant valve option can use fresh water as a coolant by connecting a garden hose to the fitting and choosing the “external” option.
