   up in the northwest, we scarf the the backup strip off and then the coupons go to a bend test. I would have like watch you scarf with scarfing gun using 1/4 in or 3/8 in scarfing gun at 300 to 350 amps and a lot of air pressure.

     the 1/4″ and 3/8′” refer to scarfing rods that go into this huge thing called a scarfing gun that is connected to compressed air and a machine capable of delivering 300 to 350 amps at 100% duty cycle. it is heavy. imagine having to hold that up all day overhead back scarfing all day on the hull of a big boat/

   @ pete flood, and every one else who’s interested: on the Miller website they sell welding calculators for the 3 sorts: stick, MIG and tig each 1,5$ metric or imperial or 4$ for the complete set. this should get you started on any welding process continue by trial and error 😉

   Hey Jody,
   Watched your 2G plate test. Thank you. I’ve been welding for a number of years and as they say, some days are diamonds and some days are owl poop. I know that there is no such thing as a magic Jedi welder, who always does it perfect. Kudos to you posting the less-than-perfect! As ever, your site rocks and I watch faithfully. Keep up the great work!

   Hi Jody,
   Is there a reference or a good rule of thumb for how much amperage to use for different metals and thicknesses for stick and tig welding? I’m not really having any problems related to this but a solid starting point would be helpful.

   Thanks,
   Pete
