Massive mig welder hell to move

[routercnc]

Hi George,

I don't know the answer to the above question, but when I MIG welded many years ago I seem to remember a spray to reduce splatter - maybe it's that?

Anyway, I wanted to also suggest that if you weld outside (to stop the garage catching fire for example!), and are using a gas MIG, watch out for the wind blowing the shroud away. It makes the weld splatter, and gives a visually, and probably mechanically, worse weld. Even a light breeze is enough to do it. A non-flammable shield might help, or wait until there is no wind.

Was talking to guy today about mig welding and reckons there's a spray that you spray on the metal near the weld area,this helps to protect the shroud from the metal and stop the wire fromwelding to the copper tip.

Was he talking a load of cobblers?

Anti-spatter spray
I can also vouch for box section warping, I made my machine from 60mm 2mm wall and it still warped a little even though I was ultra careful not to put too much heat into it.
