Which statement about GTAW torches is true?

• A. They are exclusively water cooled
• B. They are exclusively air cooled
• C. They can be either water cooled or air cooled
• D. They require oil cooling

Answer: (C)

Cooling method is what matters here. GTAW torches come in two common designs: air-cooled and water-cooled. The choice depends on how much heat needs to be removed during welding. When you’re welding at higher current or for longer periods, a water-cooled torch handles the heat more effectively and helps keep the handle from overheating. For lighter work or lower current, an air-cooled torch is simpler, lighter, and often more economical. Oil cooling isn’t used for GTAW torches, so that option isn’t applicable. So it’s correct that GTAW torches can be either water cooled or air cooled.
