Question

automotive anti-freeze is the best for water cooled gtaw torch coolant systems.

true
false

Explanation:

Analyze the coolant requirements

Using the GTAW Torch Cooling knowledge point

Automotive anti-freeze contains additives, silicates, and rust inhibitors designed for high-temperature combustion engines. In a high-frequency, high-voltage Gas Tungsten Arc Welding (GTAW) system, these additives can break down, clog the small coolant passages of the TIG torch, and conduct electricity, which can cause high-frequency arc starting current to short-circuit or leak through the coolant lines. Therefore, specialized deionized water or dedicated low-conductivity welding coolants must be used instead of automotive anti-freeze.

Answer:

• True
• False (Correct answer)
