my older brother bought a welding machine and rarely uses it so i brought it upon myself to learn how to weld. i’ve been watching all kinds of videos so i know some techniques but only started last week. any tips? i’m using 6013 at 70 amps. should i go higher or lower? i tried doing both but genuinely cant tell a difference but i think its cuz i just dont know what to look for. any tips appreciated 🤙🏾
