Need 50ft cord for Millermatic 180 Autoset...

[1320King]

I need to make an extension cord for my Millermatic 180 autoset. I would like the cord to be 50ft long. Will this effect the operation of the welder?

Also what wire would you recommend? There is already a 220 plug in my garage that is 30AMP right now.

There is a Lowes and Home Depot nearby that I can go to.

You will need to get a 10/3 Extension cord and cut the ends off and replace them with 6-50p (Plug) and 6-50r (receptacle) Wall Mount style.

You can but 10/3 cable by the foot but it actually cost more- just check the prices while yer at the Store.

If you can wait, you could order an extension cord with 6-50 Molded connectors.

Just read that you have a 30 amp 240v in the geerage:

What type of receptacle is it?

I'll second the vegetable. Cord by the foot will probably be much heavier duty jacket, but that probably won't matter to you. If that's a NEMA 14-30R receptacle in your garage, you won't need to use the center prong, just the two outsides and the ground.

I'll second Broc's suggestion about buying an extension cord rather than buying by the foot at HD or Lowes.

Don't know where you are, but if you've got a West Marine nearby, their 30A (10ga) shorepower cord makes a great extension cord for the MM180.

I have several old boat shorepower cords I use for extensions for my welders. 25 and 50' 10ga for the HH187 and 50' 6ga I use for the MM251 and the Sync 250.

I just did this this past weekend -- at HD, the 'raw' 10/3 was listed as
something over $2/ft ... and was a special order. The 50' 10/3 Ridgid
extension cord was something like $53, the 100' was something like $95.
Needless to say, I went the extension cord route. It works great
(hooking the dryer socket in the house to the buzz box out in the
driveway).

I made my own several years ago using bulk wire and dryer connections. Didn't even think to look for one already made. Don't I feel silly now.

i might have been a bit too terse with regard to the extension cords...

they came with "standard 120v" socket/plug that i snipped off
and replaced with the appropriate 230v units. the
originals are now in the garbage.

still -- cheaper than buying the wire.

i just made a 30' cord with ends i picked up at home depot and i scored the 10/3 cable from a buddy. he still has about 700 feet of it. the wire is from a fire rescue truck that he picked up awhile back because he wanted the chassis.
