Thin metal welding tricks

An auto darkening shield can throw the welder off sometimes.

On some jobs when repetitive tacks welds are used to make a continuous bead, a standard shield can allow you to watch the heat dissipate as the red turns to black then hit the trigger again.

It helps me to focus my eyes, and they are not continually dilating with the auto shield going from dark to full light.

My sons find this technique difficult but with practice it might suit you.
