Hi:

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

There are 2 spring loaded pins (1 on each side) that you push in slightly and raise the top of the pedal off as you push in.

check for ignition fuse blown

Lincoln Electric... | Answered on Jan 13, 2018


there is no seal at the feed rollers around the wire as it requires the correct gauge wire and feed hole to slow down the loss of gas at that point ( easier for the gas to escape up the wire housing and out the welding end )
the gas is allowed to flow when the welding trigger is operated as that opens a gas solenoid that allows gas to the welding wire tube to exit past the shroud around the welding point

read you user manual well to be acquainted with the machines operation, and if there is a persisting problem talk with your supplier and consider a warranty service check

not knowing what model you have makes it almost impossible to suggest a repair, however, your problem indicates a fuel supply problem, if your unit has been in storage, or not used for a while,and was shut down with fuel in the tank and carburetor, it is likely that you have fuel that has stratified, and turned into a varnish inside, which will require a dis assembly and thorough cleaning before it will idle, if it has been in use, it might still need complete carb clean, also check you fuel filter, usually it is something that is just being overlooked, spark plug???? spark plug wire? ignition coil air gap??

as with any gasoline engine, you need, fuel, spark & air, take a moment to follow the progression of each of them, you will figure it out: example, test your ignition switch, clean, new fuel, getting spark to the plug? do you have a fuel stop solenoid attached to the carburetor?
