Hi there, yes I'm a rookie! I bought a MST 251Si back in 2016 and have very limited use with it (maybe 3 hours). I'm a retired hobbyist and I'd like to learn more about setup of the welder. My other machines had a chart on the cover that would start you in a direction to go and you make adjustments on the fly. I'd like to know what other machines that have a voltage and ipm wire speed chart on their machines are comparable to the MTS 251Si. I'm not a professional welder but would like to know more on where to start instead of listen and adjust to the bacon frying sound. I looked at red & white machines that were close to the 251Si and the voltages and wire speeds were different. If there is a machine with a chart thats close to what I need to start the setup I'd be greatful on knowing which on. Thank you in advance.
