What is an important feature of gloves intended for use in welding?

An important feature of gloves intended for use in welding is long cuffs. Long cuffs provide additional protection for the wrists and forearms against sparks, molten metal, and heat exposure, which are inherent risks in welding operations. This extra coverage helps to prevent burns and injuries caused by splattering materials or intense heat in the workspace.

While options such as thick insulation and heat resistance are somewhat relevant to welding gloves, the specific design characteristic of long cuffs is particularly crucial for comprehensive protection. Waterproof material, while beneficial in some contexts, is less critical for welding where heat and physical hazards are the primary concerns. Thus, long cuffs stand out as a necessary feature to ensure the welder's safety.
