WM Blitz Video #12 115 Volt MIG 2F Corner Joint - PrimeWeld MIG180

Material type and thickness was 1018 steel 11ga  .120" (3mm)

18.1 volts 149ipm using .035" ER70S6 wire, C25 gas at 25cfh

This is a 2f position horizontal corner joint.

It is only slightly different than a 1F flat position and certainly no more difficult.

In fact, I find it a bit easier just because it's more comfortable for me.

I am willing to bet that some comments on youtube will tell me things like

"you should always push with mig".

I think saying "Always" is a pretty strong stance to take when it comes to welding.

I like to test welds by the cross section method to see the depth of penetration.

I have probably tested more than 100 mig welds using both pulling and pushing angles and am confident in saying both work fine if you avoid steep angles.

Thanks Jody for these MIG vids. I learn a lot from them. MIG is the only welding I do. Don’t have the gear for the other types. Welding can be frustrating and tricky but when you do a good weld you really feel good about it! Watching your vids over the last few years has really helped—you know what you are talking about!

In my very early attempts I was using a different gas combo to the 25/75 as here in AU they recommended using a mix called Argo Shied for steel thicknesses up to 1/8 thick (3mm). It has 93%argon. 5% CO3, 2% O3. Here, the 25/75, is only available it the largest size cylinders. Way too big for my requirements at home. In the end I used 18/82 from memory.

Here for some strange reason they make different ratios for different thicknesses of material. For you guys, it seems 25/75 is pretty well universal for any thickness of mild steel. I got better results when it switched to the 18/82 ratio of CO2 to Ar.

Have never understood why they recommend different ratios for different thicknesses of steel here in AU.
