making a 220v extension cord for my welder

[Tom]

Hi All,
Need your input on the extension cord that I made for my welder
(Lincoln squarewave 175). I did my reseearch on this site and here's
what I did. I made it out of 10-3 wire (rated for 600 volts) -
extension cord is 100 feet. The male plug is 220v 30amps and made so
that it will plug into my clothes dryer outlet. The female receptacle
is 220v 30amp outlet receptacle (receptacle with a rectangle metal
box). Does this sound right to you? Is there a higher chance of getting
shocked because my female end is made of metal (male plug housing is
plastic/rubber). Thanks for your advice!

10-3 is a US term that means nothing to me. (is it 3 x AWG10)? sounds about
right for your application.

As long as the metal box is connected to the earth conductor of your
extension lead (and the rest of the lead also wired correctly) you will
be safe.

Bye.

Yes, 10-3 (or 10/3) is #10 AWG, three conductors, not to be confused
with 10-2/WG which is still three conductors but one of them is green
for the safety ground.
