Last week I was practicing with 7018,it was coming out REALLY well.
Today not so well.Aside from undercutting and inconsistant travel speed
(my fault)there are holes in the weld.Is this porosity or just bad welding?
There doesn't appear to be any slag in the holes.
I've had rod for about 2 months and don't have an oven.
The rod has been kept in one of those plastic tubes with the screw on gasketed lids.
