  • worthless video. why post it?

  • You need more current on a mig to do Ali, as you use a DC current instead of AC like you would on a tig. I am guessing that the Ali used will be a 5083-H321 around 6mm so you will use aprox 180/210 amps depending on how fast you are moving the torch

  • mig weld on boats, longer runs.

  • Is the hull of that boat aluminum? I don't hear the "buzzing" normally associated with TIG welding aluminum. I'm just curious which welding process is being used in the video. Also, what amperage does something like that take? If that hull is aluminum and there isn't any pre-heating going on (pretty sure there isn't since the welder is IN the boat standing on the hull!) I'd imagine the amount of current needed to overcome the thermal conductivity of aluminum is large! Thanks.
