I have to arc weld some 25x25x1.6 mild steel in an upcoming project and could use some advise on technique, the last time I tried arc welding 1.6 steel it was a real pig of a job, I couldn't find a sweet spot between sticking and blowing holes.

The smallest rods I can find are 2mm.

I saw a guy on YouTube doing multiple stop starts to allow the material to cool a little so he wouldn't blow holes, how long a pause when arc welding before you need to clean up the weld to start again?
