Finding the Code Number
There are normally three ways to identify a Lincoln Electric welder:
- Product Number – letter "K" or "U" followed by numbers and/or letters. For example: K2175-1
- Code Number – 4 to 5 digit number. For example: 10859
- Serial Number – 11 digit alphanumeric. For example: U1060512345
When you register your product on myLincolnElectric.com, you need to enter the code numberof the welder. A common mistake is to enter the product number.
The code number can be found on the nameplate of the welder, located either on the front or back of the unit.
