Coolant

Protect and Maintain Water-Cooled Welding Systems

Using the right coolant keeps your torch running cool, protects your pump, and extends equipment life. Bad coolant leads to overheating, buildup, and failure over time.

What to Use

  • Propylene Glycol – Best for most welding setups (safe, reliable)
  • Ethylene Glycol – Higher cooling, but more toxic (sealed systems only)
  • Arc-Zone pick: Propylene glycol for most applications.

Mix & Water

  • Run 25%–40% glycol + distilled water
  • Never use tap or hose water

Avoid These Mistakes

Running straight water. Using automotive antifreeze. Mixing with tap water. Not changing coolant

Maintenance

Check weekly. Flush every 6–12 months. Replace annually

Warning Signs

Hot torch. Loud pump. Dirty coolant

Run clean coolant. Run it right.
