Unfortunately, I can only grind the root. Once the root is in and I get a thumbs up, I'm only allowed to use a wire wheel for cleaning.Poland308 wrote:Often no. You will simply need to grind back into your previous weld to ensure a good tie in.

Yeah the tie ins are my greatest concern.Poland308 wrote:The root is the most important. After that the wire wheel should be enough.

If you`re running rutile then starts would be as previous poster mentioned - on the start of the weld.
Rutile ss stick requires tight arc all the time, best is to just practice vertical stringers with no pausing on let`s say 5mm plate with 2,5 mm rod. Amperage for vertical is usually pretty low compared to same diameter rod on mild steel.
If the job allows it you also have rutile-basic electrodes on disposal from Lincoln, which are from my experience great to work with.

No grinding allowed after the root pass.
