Hello WW. I've been lurking here for awhile. I'm a sheet metal apprentice, and work in a commercial stainless kitchen shop. Here is my first project, it will be a wagon. My son has long out grew his current one. I did not weld it yet cause I need to practice more. I just had my 2nd Class of mig. I may just TIG it. It is 18ga, 34"x22"x6", there seems to have some mill scale on it, not sure. The last three pictures are of my best coupon. I can't get the bead to lay flat, regardless of speed. If I turn the volts up, I blow right through. Any advice?Cut with a plasma, and mostly broke up in a hydraulic Cincinnati press. Settings:Lincoln 350MP75/25.035 ER70S-6100IPM10.5 voltsTravel is not consistent. Back side penetration. Bead heightThe dime is just for size reference.
Reply:18 gauge is thin......What machine are you using......On my Lincoln 125 mig.... 18 gauge is E-4........which means low amps and low wire feed........even for 110v......Turn your amps down..... Move slower...... Make your fit up better..... No gaps.......Precision TIG 185 and MP 210Bobcat 225NTCutmaster 42O/A tanks.... 2 Argon tanks...... 2 C25 TanksFacebook......

Reply:It might be 16ga. Machine is Lincoln 350MPI don't think the machine can go lower than 10 voltsWire speed below 100 doesn't seem so smooth. My coupons didn't have a gap. I will hammer/dolly and tack the seems tight before welding.

Reply:Using 75/25 gas .035 wire diameter the chart inside the machine recommends:120ipm 15,4 volts DC+ program#5I would try with this settings, and moving the arc from one side to the otherBest RegardsMauricio
Reply:On something that thin with a MIG, I would personally run it downhill. Try setting it up on a 30 degree slope or so...Give me fuel, give me fire, give me that which I desire.
Reply:Just remember smooth edges and welds. Children get enough cuts and scrapes growing up. Good luck. A prescious time for you to be sure. I have 2 daughters quite grown now though.
