Viewports

I experimented on a scrap piece with 2.5 and 3.2mm electrodes on various power settings. Due to the close proximity of the rings to the edge of the viewports, I’m welding at a really awkward almost straight down angle.  The MIG gun wouldn't fit into this space.  Before this shot, I rigged up a similar shaped awkward weld position scrap piece and practiced until I was confident I could get these runs without any mistakes.  Eventually I used 3.2mm electrodes set at 120amps.  These E7018 rods run quite nicely but I did find them difficult to re-strike.  However taking the end back off on the bench grinder helped to get the arc started again.
