Installing welder in my garage

I have a new 225 Lincoln stick welder I got for Christmas. I will need to add a 220 outlet and circuit from my sub panel.
I am assuming I need a 50 amp breaker. What size/type wire do I need? Would it be best to use conduit? All I could find at Lowes are suface plugs. WIll these be adequate and can I use them with conduit? ANy help would be greatly appreciated!

Does your welder have a plug? You can tell by that what the circuit needs to be. If not look in the book. What wiring you use depends on the situation that you have. Is your electrical panel on the garage? If so you could nipple out the back and out the outlet on the wall.
Assuming 50 amps you will need 6 CU or 4 AL.
Surface plugs are fine, check the openings out so that you do not get into a tite if you run conduit. Some the surface plugs I have used are pretty tight if you come in the back or bottom. You might need to go to a real electric supplier to get the plug and cap you need. Welding shops here in Phoenix carry them.

You can use wire as small as #10 copper because the duty cycle of that welder is < 20%, but I'd use #6 or #8 and a 50A breaker. #10 could cause problems down-the-road if someone plugged in a 60% duty cycle welder. I think the plug you need is called a "NEMA 6-50R", and the receptacle that I bought has a built-in cable clamp that can be removed with a few screws and replaced with a 3/4" conduit and locknuts.
BTW, I though Licoln welders came prewired with a cord and plug, and a they included receptacle for you to wire up.

You want real help, call a qualified electrician out to do the work for you! Getting answers to questions in this newsgroup will get you killed and have your house burn down. If you are going to ask for help the least you can do would be provide photos of your garage, your main panel, your sub panel inside and out. Check to see if your lugs are tight to begin with. Are your going to run surface mount conduit for through the walls. If in the wall we will need a photo of the inside of your wall too. As you can clearly read, you are going to need real help!

Just in case your wife is going to weld, we need photos of her also.

Standard practice is to use a 50 ampere 4 wire range plug and receptacle using a 50 ampere two pole 240 volt breaker and No. 8 copper SER or equivalent cable rated for 90 degrees C. but used at its 75 degree C. ampacity. The reason for this is that the range parts are relatively inexpensive. However, the manufacturer's listing instructions are the law and should be followed.

Check with the local electrical code book. It should tell you if you can derate the feed due to the duty cycle. But if you derate the wire, you also use a breaker that will peotect the smaller wire or you will burn your house down.
