["You are lining a rectangular drop on the ground using a pneumatic resistance pin spotter (weld gun). You pull the trigger quickly, but you don't apply downward force, and you can pull the insulation pins straight out of the metal sheet with your fingers.", 'Resistance welding requires both intense electric current and solid mechanical pressure to fuse the pin base to the steel panel face. Press the pin spotter tip down hard until the internal compression spring bottoms out completely, then pull the trigger. The likely recovery is to check the tool setup, correct the prep or technique if it is within your assignment, and bring the journeyman or foreman clean information before the work creates rework overhead.']
