What type of welding tip is best for repairing hard-to-reach areas?

The round tip is best for repairing hard-to-reach areas because its shape allows for easier maneuverability and access to tight or intricate spaces. The rounded design helps reduce the risk of damaging surrounding areas during the welding process, providing improved control in confined locations.

In contrast, a flat tip may be less effective in tight spaces as it has a wider surface area that can hinder access. A pointed tip, while designed for precision applications, might not have the necessary coverage for broader areas that need repair. The universal tip offers versatility but lacks the specific advantages provided by a round tip in terms of access and control in difficult locations. Thus, the round tip is ideal for ensuring efficient repairs in challenging scenarios.
