No they were 4.0mm you could not have done it at 190A with the access and the rod angle you wouldn't control the weld pool that is the top whack for a 4.0mm low hydrogen They tend to run across the range of 120-190 depending on what you are trying to do (Amperage ranges can vary slightly with different manufacturers on the same electrode type)OK - - - - I thought maybe, using stringer beads as outlined in your pdf, that might be what one would do.
Still a cow to do - - - me, your amperages - - - that would be for 3.2 mm electrodes - - - for 4.0 I would likely be in the 190 A range.
Need to have things 'hot' to keep that slag burned out. Even with cleaning between passes (likely wire brush of some kind) if you want clean welds with very very low to no porosity - - - you will be running HOT. (Keep a tight weld arc and the high heat isn't an issue!)
I hope that this was horizontal or flat welding - - - - vertical up would have been a serious gong show (IMO). (And for overhead - - - - find another turkey would have been my response!!!)
Isn't it amazing what the guys on the tools have to fix for the suits that can't get things right - - - lol
The weld position was carried out as per drawing on PDF
