Resistance Spot and Projection Welding

Welding current is the most important parameter in resistance welding, it directly correlates with how much heat is generated on each weld. And the enemy of repeatability in resistance welding is heat. When heat has been taken care of properly, not only will your tips last longer but your project repeatability will most likely also improve. By insuring your electrodes are cool, you reduce the number of rejected parts, thus increasing parts produced, while increasing electrode life!

Let us help you decide which Chiller or Recirculator is right for your application.

• Understand the effects of Insufficient Cooling
• Water / Glycol cooling ratio, providing proper care of your Koolant Koolers chiller

We provide help in sizing water Chillers and Recirculators

Properly sized welding chillers provide significant savings:

• Lowers water and sewage bills.
• Provides solid protection for processing equipment 24 hours 7 days a week.
• Reduces the number of rejected parts, thus increasing parts produced.
• Maintains a self sustaining source of properly chilled water.

How to Size a Water Chiller Correctly

Specify the proper chiller for your load requirements. An undersized chiller will always be a problem and will never properly cool the process equipment. Here is a table to help calculate your load requirements.

Simple Instructions to Assure Proper Cooling

BTU=Constant (Weight of Water) x GPM x Temperature

Differential

Multiply the fluid flow (GPM) by 500. Multiply the result by the temperature differential or rise (return water temperature minus the input or supply water temperature). Divide the result by 12,000 and you now have your required rating.
