it's not easy to get neat welds with mig on thick material unless you have a really powerful machine and then it just pulls out of alignment more.

Not strictly true, with the correct setup and a skill full welder then even a cheap welder can give excellent welds on thick material without too much pulling or distorting as you can see on these pictures of machine we made, one is 5mm plate onto 10mm done with a Cheap £150 180A Ebay Mig, the other is this base frame with some long welds on10mm plate.

You can see the Mig in the pic of the base frame and if you zoom in you can see 10mm pads welded to a 10mm plate, nothing pulled on this frame. Full disclosure here this was My Son Jareds (Jazz) welding, not mine, my eyes are knackered so my welding days are done.!

This said practice makes perfect and a grinder mask's 1000 sins until something falls off...
