Answer: 
Hi Shmit, this product is rated at 230 volts, so you will need the proper breaker, and circuit to operate this welder.
Most houses are rated 125 volts. So you would not be able to use, unless you install the proper circuit.

Answer: 
They DO make an aluminum stick type rod that CAN be used to weld Aluminum. HOWEVER, THIS IS NOT IDEAL And, will NOT have the strength that using a TIG welder would provide.

Answer: 
A fuse is a bit old fashion now. It is a thin wire that melts ( fuses) when current is too high so 'break's the circuits continuity.
Go for a breaker at 50 amps. That will be a 2 pole type.
That will interrupt the power on overload and is re-settable.

Answer: 
I can not be certain as I do not know the context in which "fuse" is being used. HOWEVER, in many older homes that were built BEFORE the advent of Breakers YES, they used fuses to protect the circuits from over loading. There are several different types of fuses so be sure to get the correct type

Answer: 
Hello, Machine has no fuse. I believe you are talking about the line service, and your breaker box should have a 50amp breaker for the welder to be plugged into.

Rated 4.8 out of 5 by 30 reviewers.
Rated 5.0 out of 5.0 by Lincoln AC 225 welder.. Had one years ago. need one now,, Home Depot had the best price and it was in stock. a true no brainer.. August 16, 2016
Rated 5.0 out of 5.0 by good value HEAVY! put some wheels under it, bought to weld stairs, have not had any trouble, helps if you know how to weld July 5, 2016
Rated 5.0 out of 5.0 by Purchased THIS welder OVER 25 Years ago and, STILL WELDS GREAT!! Purchased THIS welder OVER 25 years ago and, STILL welds GREAT!!! I have had Trucks all my adult life and, heavy equipment too for a while. Never been a "wealthy" man so I have always bought used equipment and, fixed it myself! And, I can tell you first hand THIS Welder HAS the POWER to penetrate HEAVY Metal! Always be sure to clean ALL your surfaces! (ground too) The Trick to getting it to Stick is PENETRATION!! The ONLY other thing I can say is that I have never had any formal training as a welder but, I NEVER had ANY weld fail. NEVER! Again the trick is PENETRATION and, CLEAN your surfaces! That being said, many "REAL" welders (like certified ones) have told me that IF I liked welding with THIS welder I should try the AC/DC version. They ALL say the DC welder works better and, is easier and, makes a nicer weld. Well after I returned to Pittsburgh from NC. I went to work for one of the local trucking companies and, they had an AC/DC version of this welder and, I used it many times and, I can NOT honestly tell you that I noticed any appreciable difference what so ever. Maybe it might have been a little easier to get the rod started. But, I never really had any trouble getting a rod started anyway. Please DO NOT HESITATE for one second. THIS IS A GREAT WELDER! It has NEVER let me down!! NOT EVER!! 26 years atleast! And, I have NOT been nice to it either! Run it hard and, long and, under harsh conditions too! NEVER a problem. GREAT WELDER! October 9, 2013
Rated 4.0 out of 5.0 by no wheels in box This thing is so heavy and there are no wheels in the box. That is my only complaint November 14, 2015
Rated 5.0 out of 5.0 by BigT After 40 years of long and faultless service, my old machine is needing a rebuild. I love my ol machine. Have welded everything from body metal to antique car frames to 3/4 iron bar.If you get one of these tombstone welders, you too will be happy. Just a good solid machine. September 6, 2015
Rated 5.0 out of 5.0 by Simple, powerful, quality and great value. I purchased this welder from my local Home Depot and it exceeded my expectations. You can't find a better value anywhere. Straight forward layout. Strikes an arc with ease. Built to last. It's everything you'll ever need to do most welding projects and it won't suck your wallet dry. This is Lincoln's best selling model of all time...and if you purchase one you'll see why. Novice or pro...you'll be very pleased. Nowadays it's hard to find a good quality product that does the job it was intended to do and doesn't cost an arm and a leg. Kudos to Lincoln and Home Depot. Would recommend this welder in a heartbeat. February 19, 2012
Rated 5.0 out of 5.0 by This welder is "The Machine To Have." When it comes to welding, weather it is a new project or repair job, this machine excels at it, you do not have to worry about it letting you down. With the wide selections of electrodes available, even aluminum can be stick welded with it now. I've welded many times over the years with this machine, and when I got my shop at home, I bought this great machine for my new shop. It's dependability, ease of use, and wide selection of uses will keep this welder a staple in most shops. You can buy a more complicated and expensive welder, but not a BETTER WELDER! Home Depot has it at the best price around, and all the accessories you need, such as the correct electrodes, etc. You will surely be more than happy with this machine. June 28, 2012
Rated 5.0 out of 5.0 by Great product at a reasonable price. Welder does a great job around my ranch. Just the right size for my needs. Even welded 5/8 steel with surprisingly good results. Easy to use. Burns stick after stick with no issue. Highly recommended. January 6, 2015
