A trick that I use is i take a bolt and tack it to the piece I'm welding in. Then put the ground onto the bolt and hold onto the ground clamp as I tack it in. Finish the job and break off the bolt. Remember if you do it this way the current is only running between the stinger and the ground. Saw a job on a new wheel loader welder put a ground on the back of the loader did some retrofitting around back counterweight and then moved to the front to work on the quik-attach bucket,.... didn't move the ground. Finishes the job and owner picks up machine,,,,, immediately complains of a binding sound in centre of machine.... Problem was electricity flowed from back of machine at ground to front of machine at stinger (welding rod) in the middle of the machime are bearings that allow the machine to articulate. Electricity arced across bearings and ruined them. Two days later and several thousand dollars out the door machine was once again ready for the owner to pickup. NO profit in that job.
