Quick Welding Question

[Mdub]

I'm a noob welder. I'd like to weld some 3/16" thick steel to D30 axle tube which I understand is 1/4". I'm using a Lincoln 220V 175. Do I set it to penetrate the 3/16" or 1/4"? Thanks.

Yes.



If you know exactly what setting will penetrate 3/16 and what setting will penetrate 1/4 you're already a better welder than I am. Set it at what you estimate will work, and then adjust it a little to fine tune.

Probably won't burn through 1/4 or 3/16", but you're better off to set it low and work up. I think it's a good habit to get into especially if you plan on welding smaller stuff in the future. It's easier to grind off crappy welds than it is to fix holes that you burnt through.

welding is like makeing love to a woman, you need to get deep penitration!!

make it hot, work it well and get it deep!!

if you burn through, let it cool for a second then fill the hole up and keep going. you want to set it hot and adjust it cooler or you will get crackes and the welds will fail on the cooler welds.

Put a 45* bevel on the 3/16 plate, set welder to max, and go to it. Your not going to burn through either the 3/16 or the 1/4" tube with the 170 amp welder, in the circumstance described.
You didn't say what type of welder (stick, TIG, MIG, or wire feed); but, not likely to burn through the 3/16 plate welded to 1/4 axle tube, with any method at 175 amps.

Set it to the max what? Heat or wirespeed? Vertical or horizontal pass?

With a mig, a monkey can melt two pieces of metal together...........

Might want to practice with some comparable sized plate to determine your setting before moving on to the axle, practice make perfect.

Don't know Lincoln settings but I use a Miller 230v 175 and I would start with the Voltage setting around 6 (0-10 scale) and the wire speed @ 65-70-ish and fine tune from there.......but that's me. I don't pay the bills by welding (did 20 years ago) but I've yet to have anything I've fabbed for my Jeep break, fwiw.

Thanks for the inputs guys. I'll let you know how it turns out when I get to it.

Id definatly have to agree with Troy, Ive never met him but ive enjoyed looking at the sexy welds he makes.
