just got a new muffler, i have a mig welder in my garage and i know how to weld i just don't know what settings to make it?
gas psi?
wire speed?
voltage?
it's a steel muffler
Gas flow is actually in cfh. Set to approximately 35 cfh.
Wire speed and voltage settings all depend on the type of machine you have. Does it have actual numbers or just letters and lines? I would suggest getting some scrap pipe and playing around with the settings.

No offence here, but if you have to ask that, I would let some else do the welding. Unless someone else here has the same exact welder as you, and is using the same type and thickness of wire... No one will be able to give you the best settings. Not even that, every welder has his/her own favorite settings depending on what he/she is welding.

well i just need to know what would be best for a pipe and a steel muffler lol , low wire speed since its thinner metal im guessing?, and its a miller millermatic 250

It's been a while since I saw one of those. That has the analog dials on it correct?
What is the scale for the voltage? I'm assuming that you're using .035" solid wire. Set wire feed speed to 190 ipm. Voltage around 17-19 volts. If it has the same dial set up as some of the older delta-fabs, set the voltage dial at approximately the 9:30 position. If it spits and sputters, slightly increase the voltage. Play around with that wire feed speed on a piece of scrap till you get the voltage set correctly. Set the voltage low so the wire will stub into the part intentionally and increase until it is a nice and smooth frying sound.

Yea .035. I just go by sound lol, feel fortunate you have gas. I flux cored my entire system lol. Just a hint, Ford does use a low grade stainless. As said -Practice piece first will set you up.
