Anything welding

Regular steel will start pitting with centerfire rifle making the richochets wildly vary in direction.
I welded together 2 1/8” plates and 556 bounces off the front plate but pits it, and 6.8 SPC penetrates both layers at 80 yards.

Get some AR500 steel and make targets out of them or just buy some AR500 targets, it’s worth it in the long run.

For the pistol calibers you can get away with mild steel mounted at an angle, but I would make an angle iron brace across the back of the plate to keep it from warping, my .40 at 15 yards after a couple of mags had bent the doubled up 1/8” plate target I made.

 

Welded up! Not too bad for this noob.

 

Still learning. 3 passes, one handed, vertical.

 

No welding job in my future. I'm learning for fun and welding as a hobby I guess. Instructor told us to do this as it will be part of the certification.

 

Working in a fresh water set up, all stainless parts that touch the tank. I jet ski a lot and having a fresh water supply on the beach to flush skis is awesome. This tank will hold 5.43 gallons has a 3GPM pump @80psi 14amp 12v pump. I will also be adding onboard air with a small tank and a 1.3SCFM 12v compressor, just enough to re-inflate tires after leaving the beach. I’m currently just starting but you can get the idea.

 

And finally, single pass vertical, downhill.
142 amps, 18.5v, 90/10 gas.

 

Good lord, yes!

 

If they dont make it, build it. Nice work!

 

What is 100 co2 good with?

 

I've actually only used 100% co2 with my Miller 211

 

It gives more penetration but more splatter .

It was the Go to Gas for Steel.

As the Mig process was used more in finished production type goods the 75% 25 % mix was developed to reduce splatter and cut down over all costs

 

“Spatter”

 

I think he means cut down labor costs for cleaning up the spatter, not the cost of the gas.

 

My MM211 uses about a pound of co2 for a pound of wire at 20-25 cfm.

 

I Have always spelled it with a l the last 45 years doubt I will change now Might be a regional thing it was how we spelled it in school

You would shoot me if I said What I paid for Shielding gas When one does favors For The Distributors I get the Family discount

Gas is cheap when compared to labor even more so if said employee is doing something more productive that could be billed at $100.00 plus an hour

 

Yes

 

At first I was using my co2 bottle that I use to air my tires up but just recently picked up a bigger 20lb tank. That should last me a very long time.

 

Yeah, for what I do, it works fine. These were all welded using 100% co2:

(not the weld at the tube)
