This past weekend I purchased a new AC/DC 220 volt stick welder for my
shop. I plan on installing a 50 amp breaker in my box and establish
an outlet for the welder. I purchased 8/2 wire to make a long
extension cord for the welder, but local hardware store only had 6/2
wire onhand that I purchased to go from fuse box to the outlet. First
question.....is 8/2 (25 feet long) going to work as my "extension
cord" for the welder, and (second question) is there any problem
using 6/2 to run from my fuse panel to a outlet for the welder??
Since I did not have time to wire this up this past weekend, thought I
should take advantage of the knowledge here before making a dumb
mistake. Thanks for the input...

( I have all the correct outlets...and service into the shop..)
