Replicating Factory Spot Weld Appearance

[Schonyenko2]

My God, that's just nuts. I've ran those spot welders in production mode. They are set for single spot, or automatic.ie: you push the button, and let go. 1 spot. When you're running production, you hold the button down, and pull/push the jaws, and it runs on automatic. That's why you get some tweaking on the lip edges as it 's moving, grabs, and spots. There are some times high, and low heat buttons for heat/penetration. That will make a difference on the depth of the spot. You also need to dress/sharpen the copper points during the day as they flatten out with use. Or the heat setting could be off, then you call an electrician to come fix the setting, and you go set on your a$$ on down time. Damn unions.
