For what type of material are air cooled torches typically used?

Air-cooled torches are typically used for welding thin materials that require low amperage. The reason for this is that air-cooled torches use ambient air to dissipate heat generated during the welding process. In the case of thinner materials, the welding process demands a lower heat input to avoid burn-through or warping, making it suitable for air-cooled applications, where overheating can be a concern.

Air-cooled torches are limited in their ability to handle high heat generation, as they rely on airflow for cooling. Therefore, when working on thicker materials that require high amperage, it is generally advisable to utilize water-cooled torches, which can accommodate sustained high temperatures without overheating.

In essence, air-cooled torches are ideal for applications where the welding operation requires lower amperage and thus generates less heat, making them perfect for thinner materials.
