[countryboy281]

Some one please help any advice will be greatley appericated.sorry i know i cant spell. Anyways i have moved onto the e6011 lap joints in the h position and i am having so much trouble with it. In the flat position was easy but now that its up in the testing stand its a new animal it feels like. My requirements are to make it ofcourse sound and slightly concave but as well as no step to fill the edge over. But i cant seem to keep the weld from being convex and having undercut.i am new to this and its smaw by the way.thanks for your time

Slow down your travel speed a little. Make sure you have the right angle on your rod and short arc.
