I can get the machine to spray and pulse while welding flat, but when I go to weld vertical its messy. I have no clue how to set the machine for pulse. As soon as I set pulse the wire speed and voltage setings change and automatically go to 400. please help me I need to practice for my mig cert on Wednesday. also what should the gas setting be ?

Also running ER70S-06 with 88-10-2 gas, should I be running 03 wire instead
