What material is the torch body typically made of?

The torch body is typically made of metal to conduct electricity effectively during the welding process. Metal not only allows for efficient electrical conductivity, which is crucial for optimal performance in gas tungsten arc welding (GTAW), but it also provides durability and strength. Metals like aluminum or stainless steel can withstand the high temperatures generated during welding while maintaining structural integrity.

Using plastic, wood, or composite materials would not adequately support the necessary electrical connections or thermal management required in a welding environment. These materials lack the necessary properties to conduct electricity and may also compromise the durability and safety of the welding process. Therefore, metal is the ideal choice for the torch body due to its conductive properties and mechanical resilience.
