Looking for information on welding wire
(OP)
I am looking for information about the difference between 309-15 and 309-16 stick wire. I have used the two wires on pipe welding in a 6G position and found that the 309-15 will run like a lo-hi rod but the 309-16 clumps up and drops out I am looking for a answer because most of the rod manufacters will tell you there is no difference





RE: Looking for information on welding wire
For the E309-15, this is a lime fluorspar coated electrode. I believe that this covered electrode is only used in DC mode. The weld deposit is tough and is east to use for all-position work.
Use the AC mode with the E309-16, and see if this improves the situation. Is this new weld rod that was recently purchased or stuff that has been on the shelf, open stock?
Also, what are the base metals that you are joining?
