Welding on your rig?

admin

I have noticed on several of your rigs you have vices mounted. Are these for holding something to weld or other purposes? The reason I ask is I want to build a fold down fab table on the side of my welding trailer. I have a Lincoln 225 weldan g7 and I was told years ago to never strike an arc on the trailer or truck the welder is on. Is there any truth to this? I need this fold down fab table but I dont want to have to separate it every time I setup.
Reply:I was a little apprehensive about it too. Thought maybe the current could make it back to the charging system, but all that it isolated from one another. Then I got to thinking about it and realized it doesn't matter because electricity is always trying to get back to its source anyway.I welded on my trailer with no ill effects
