If you cant see weld seam good,run a chalk line along it,this helps.
If you can't see good you can't weld good
IMO..Try to think of welding as an art. Don't rush it.Enjoy it.I do

|71gtx||The cover on my miller says that for 16 guage, i should use 3.0 volts and a wire speed of 70. Seems like you are all stating 3.0 or so volts, but the wire speed is a lot higher. I tried setting it like this and it burns nice, whereas 3.0 at 30 sputters. However, I don't want it to burn too good!!|

Kruzer is right, however I think those settings are more for continuous Welding (don't know anyone who would do much of that on 18-20 Gauge though ) than spot Welding 18 Gauge-I have mine set one "click" higher (hotter), and the Wire speed faster than my Machine suggests for 18 Gauge (again, this is on a Lincoln 175 Mig)-doing so, mine will put down a nice, hot, flat spot-Weld with good penetration-I would suggest you try a hotter setting up to burn-through then back off (of course, use a practice piece for your test)-

|pepi||Having the 135 I set the heat to 3 and the wire to 3.0 and adjust from there, this is welding sheet metal to sheet metal, these are hot settings and could bulge so test on some junk stock, the ranges should get you to the ball park|

|kruzr||Most migs have approximate settings inside the lid,practice the settings on what gauge steel your using. Be sure to have a good power supply to the machine for best results.Use a heavy xtension cord plugged close to the sevice panel....good luck|

Try "C" and #7-I use Lincoln .025 wire-you are only going to spot Weld, correct?
Oops! Please disregard my settings! Apparently old age has crept in, as I did not read that your Welder was a Miller-sorry!

What's a Good Welder Setting...
I have a Miller 175 Mig Welder. I am currently fabricating a 31 studebaker. I have to weld cross members on the inside of the body to keep it from shifting when I cut the top off. I have done a decent amount of welding, but only on structural components with 1/8" thick of a wall, not caring if the other side of the material showed a bulge from the weld. However, now I need to weld onto the thin body panels from the inside without showing any kind of bulge from the outside. What's a typical welder setting (wire speed and power) for this kind of work? Also, what thickness of wire is commonly used? Thank you.
