The fitup is very critical and this is really a pain compared to GTAW. The advantage for doing this was welding the root pass in a composite (SA210 A-1 Core with 304/8 clad) window weld. The SMAW process is better suited for these type of welds since the joint is welded through an opening (Window) cut in the tube. This opening doesnt always lend itself to sticking a tig rig and wire and being able to see whats happening.
Some of the electrodes I have used made me feel like I was a good stainless welder and others made me wonder if I had spent the last 20 years of my life in the wrong trade.
Small stringer beads are the preferred method. Some people have fine looking welds using a weave but SS doesnt need to stay hot any longer than needed so I suggest stringers.
The thickness of the base metal can affect your ability to stick weld SS. The thicker, the easier. The more energy that can be absorbed by the material, the faster the puddle cools off. The faster it cools, less time to sag.
My last experience with SMAW SS was typical of the 2nd situation described 3 paragraphs above so I may not be much help!

Indicates that this is an electrode: 70: Indicates how strong this electrode is when welded. Measured in thousands of pounds per square inch. 1: Indicates in what welding positions it can be used: 8: Indicates the coating, penetration, and current type used (see the classification table below) X: Indicates that there are more requirements. Basically, D1.1 F numbers are assigned to SMAW electrodes (F1 through F4) based on their operational characteristics. I.e., how easy they are to use. I’ve often heard the F number referred to as the Frustration number. SMAW electrodes are assigned a higher F number in conjunction with an increased skill level. Blue Demon 7014 Plastic Iron Powder Carbon Steel Electrode Best Welding Rod for Steel These copper coated carbon electrode welding electrodes are perfect for Spot welding. (Amazon Link) Blue Demon offers an excellent welding rod selection, providing you with options for choosing the best welding rod sizes and packages based on your personal use.
