A mechanic struggles to remove a rust-welded control arm bolt from a vehicle due to limited access, expensive blade consumption, and uncertainty about using a torch without damaging surrounding components.

Existing tools are either too expensive (blades wear out quickly), imprecise (torch risks damaging brackets), or potentially unsuitable for tight spaces, leaving the technician without a reliable, cost-effective method for this specific rust-welded bolt removal task.
