Code 81 mean an overload to the system, this problem occurs when the wire is not running freely from drive rolls to the contact tip. To avoid this problem do the following troubleshoot.

1) Make sure you have the right size and type of drive rolls for the wire you are using. P.e. if you are using steel core wire (gas use) you need U-grooved type, if flux core wire then you need knurled type.

2) Check your tension at the idle roll pressure setting, this one must be 3-4 if using metal or flux cored wires. Less for aluminum and more for S.S.

3) Check your liner if there is any kink on it, change it.

4) Change your contact tip if needed.

5) Check the tension on your wire spool holder, this one also must run not so freely but free enough to avoid wire nesting.

Hope this help.

If this was useful to you please vote. Thanks.
Your wire must run smoothly

Lincoln weld pak 100, no heat penatration on the D setting

I believe your voltage control rheostat (potentiometer) must be worn out. Check your owner's manual for the part number and request it, it's not expensive and it is an easy part to replace. If you are doing that would be a good idea to do the same for your speed control rheostat.
Or clean them if you can, take off all the carbon particles that it build up with the time.

Ebay is a maybe. Guns are somewhat interchangeable, so it might be better to get the gun which has the tips available more readily.

You might try your local welding shop first, followed by an online vendor who carries perhaps Tweco, Northern Tool, Enco, Harbor Freight maybe.

I have a lincoln power mig 255 and every time i weld little holes appear in the welds. what could this be?


This could be a problem of gthe gas you are using. Make sure to use mix 75/25 argon/CO2 for mild steel welding, argon 100% for aluminum and trimix helium/argon/CO2 for stainless steel.
Also check your heat (voltage) 16-22 is enough for weld of most steels less than 1/2 inch.

350mp with 25ft. python push pull all of a sudden black carbon sute both sides of weld this welder has always been a great welder sent to dealer but came back same we are welding 4043 .035 aluminum wire

I had this problem with another brand,but the same solution should be effective on your Lincoln. All I had to do was clean my inert gas opening at the "stinger",allowing more argon to shield the weld. If this fails you may have excessive oils or paint residue at the joining edges. Good Luck!

Warning light

That is the check-engine light. It means something has failed and caused a fault code to be stored in the car's computer. Take the car to AutoZone and ask them to do a code scan (it's free) - if you do this at a dealership, they'll charge you an hour's labor. Have them write down the code(s) for you exactly as they appear (such as Pxxxx, where the x's are numbers), and then post the codes up on here as a reply to my message. Then we can start the diagnosis.
