If your machine has auto settings as my Lincoln does they seem cold. If its say 1/4 I'm welding on the horizontal or vertical I set it to probably 3/8. Joining 1/4 to 1/8 I'd probably set it for 5/16 and keep the arc more on the heavy metal. With it set to 1/8 your not burning into the 1/4 plate at all, the weld will be just laying on top. Thats one bad thing about a mig, you can make a lovely looking cold weld that didn't penetrate at all.

Free advice is worth exactly what you payed for it.
