I don't often use pulse for aluminum but it is a feature that can help you learn consistency.

For the first topic in this video I set the pulse rate to 1 pulse per second with the background to 33% and the pulse width to 50%.

I add filler rod on the high part of the pulse and of course that means I add rod once per second.

If you consistently add rod at the same rate and also travel the same increment in between adding filler rod,  you are bound to get some uniformity.

The second topic is on learning to MIG weld better.

I have found that stacking or padding beads with intention on a piece of flat plate is great practice.

I recommend reducing wire speed from what the MIG settings chart might say because a bead on plate does not require that much wire speed and because slowing wire speed slows down travel speed and allows you to be more intentional with your learning.

So instead of using the recommended setting of 236 ipm, I reduced wire speed to 200 and it really helped control the bead. 

I could have probably set wire speed even lower to around 190 but at some point you start to get more spatter with a wire speed that is really slow.

that is the cool thing about this practice drill is that you can learn all about settings, gun angles, stick out, etc on scrap metal.. But only if you pay attention and do things with intention.

Just running beads all willy nilly will just waste wire and gas.
