Floor Pan Sheet Metal Thickness
Anyone know what the thickness is on the SC floor pan; i.e., steel gage. I'm guessing it's around 16 gage. I need to weld some clips in for the crotch straps, and I have a new wire feed MIG which I don't quite have the settings right on it yet.
Thanks! Pat

When the floor pan is at bare metal it's closer to 18ga. I know it's not 16.
On my mig welder (Lincon Weld Pac) the amperage dial are lettered. 'A', 'B', etc. and the wire feed dial is just a dial with a pointer. As far as the setting. On the floor pans or most sheetmetal work, 'A' is too low, except if the metal is real thin. You are using an inert gas aren't you? You should find that the 'B' setting is perfect. Because on 'C', that is better for welding medium steel angle or for mock-up tools. As far as the wire setting, mine is almost always between the twelve o'clock and one o'clock posistion. Remember to use a 'weld-thru-primer'. Good Luck.

You want to used .024 wire and make sure you use the right tip! .030 will just keep burning through. My MIG has infinite settings, but for sheet metal I usually keep the amps on around 3 1/2 and the speed on 4.

Thanks guys. I just got a new Lincoln 3200. I've been practicing on some scrap with 0.035 flux core. I need to pick up a bottle of gas this week. I figured it would be best to ask, as I don't want to blow a hole in the pan right off the bat. My Lincoln has the A-B-C-D settings, and a feed dial which I believe goes 0-10.

If you are overlaying the sheet metal, you can use the 16, which is easier to find around here. You need to hold the tip favoring the thicker metal to get even pentration when using disimilar thicknesses. ON my Lincoln I use A sometimes and hold the tip almost vertical. The angle of the tip is your "infinite" adjustment between the letter settings. AFA feed, I use 3-4 on just about all settings except the highest. There, I find you need a little more wire. Remember, with welding, you are fusing metal. The wire is there to transfer the electric current and provide SOME fill. In gas welding, the rod is used as a tool to control the puddle, keep it the right temp and add some filler as you go. Sometimes less is more in welding. The wire feed works much the same way when you thinnk about it. You just can't stick the wire in the puddle like you do with gas. Watch the red puddle, not the arc. The puddle is where the action is. |

Also get yourself one of the instant dimming welding helmets. Makes a huge difference when you are welding.
