Glenn- while I am no expert on stick welding, I have always allowed welds to cool at their own pace. With the shock of any quick cooling, there is usually a risk of weld embrittlement- especially at the margins. But, I recall that the issue is less crucial when you are talking of removing the slag from such a weld. A quick heat-up with a torch and natural cooling will stress relieve the weld in most cases. When tigging chrome-moly(4130) chassis welds, I would mark with Tempilaq and bring the joint to kickover-then allowed ambient cooling. The need for all of that is dictated by critical use.jet
