A good way to test for penetration is the cut and etch test.
If the test is done while the weld is still fresh on you mind, there is a lot that can be learned and welding technique can be adjusted and improved.

Can you Spray Arc with 80-20 gas? Yes

In this video, I go over mig welding settings for short circuit mig welding in horizontal and vertical uphill. Also a quick tip for vertical uphill settings. Arc shots and techniques are shown in detail.

For Out of position welding like vertical uphill, Short circuit mig welding requires some manipulation of the gun to prevent excess convexity of the bead profile. Dual shield flux core is different. This video shows the distinct difference in speed and bead profile

Science might say no but after a period of non use, rolling the tank sure seems to help the arc smooth out.

In today's episode we'll be going over a D1.1 1G 1" thick welding plate. We'll be using .045 ER70S6. 1G Pulse Spray mig

The 3G plate test is sometimes used for MIG welding certification tests.

This video will be particularly helpful for a 3G certification test with uphill and downhill root passes.

Weld sequence can help prevent distortion.

Mig welding basics, machine settings, fundamentals; getting started with MIG welding.

Jody Collier from WeldingTipsAndTricks explains one of the best MIG gun techniques for beginners.

These technique tips will help you get better penetration (yes, that's a technical welding term), proven by testing.

Now that Jody has you started, it's time to practice practice practice.

He'll explain some starting tips for voltage and wire feed settings, and will explain in a little more detail how to start refining your MIG welding technique.

One of the best ways to get a lot of practice with a small amount of metal is stacking beads on a tee joint.

Remember, "practice makes better" (because perfection doesn't exist).

One of the most important concepts in welding is POSITION. Let's talk MIG welding, vertical uphill.

Mig welding vertical uphill requires using some manipulation to prevent the weld from being too convex. Proper settings (lower settings than what are normally used for flat and horizontal) techni...

Mig welding overhead is mostly a matter of getting comfortable. Again, POSITION.

The same settings and techniques that are used for flat and horizontal also work on overhead. But if you typically weld really hot, reducing the wire speed by 10% might help.

In some industries, a certain look is expected for MIG welds. For example, the motorsports industries has adopted the "MIG like TIG" look.

It involves using settings different from what is normally used for production. Wire speed in particular is usually much lower, which lowers the overall trav...

MIG welding thin wall square tubing in a common fixed position.

MIG welding uphill requires lower settings. A pro tip is to just use the chart or auto settings for thinner metal ( 2 thicknesses usually works well).

Using a push angle vs a pull angle is an argument that shouldn't even exist, but folks continue to argue. Both work.

For spray transfer MIG, pushing is usually best. But for short circuit MIG, both pushing and pulling have their place... and that's a good thing because sometimes you don't have ...

If you're just looking to keep things simple, this one MIG technique works for all positions.

By tracing the front leading edge of the puddle, this one single MIG welding technique gets penetration in every position.
