I will need to weld some tabs to the axle housing so the stick may be the way for that.
Why? Welding it outside?
If had a MIG at my disposal, and I wasn't working outside in the wind, I'd choose it every time over a stick. Stick is good for welding farm equipment outside in a tornado. Beyond that application, stick is obsolete, messy, ugly, slow. MIG is so much easier, faster, better looking, and equally strong in the right hands...assuming the welder supplies enough voltage for proper penetration.
Just my thoughts on the subject. Others might vary. But I feel stick is of little or no value on any car part. TIG however could be a useful feature someday, especially if you intend to do any aluminum.
