I’m going to give stick welding a go for the first time today and, in preparation, I’ve been reading up on the topic and looking at various YT videos.
With respect to the amperage required for different thicknesses of rod, I read about a rule of thumb that for every 1mm of rod diameter you should use about 30amps current. Any stick welders that can confirm that or give me some similar guidance?
I bought two packs of E6013 rods 1.6mm and 2.5mm. My understanding is that the smaller rods can be use for things like chassis welding where the plate thickness is 2-3 mm and the thicker rods for things like engine mounts at 4-5 mm thick plate? I just want to check that this is correct before I have a practice.
