Questions and answers
my 140 w/gas will only spit weld an burn havent used alot but this is new,do you think something could have burned out thank you
Your Lincoln Electric Pro-MIG 140 may only be spitting weld and burning because the wire inside the welding whip has melted. This can happen if the whip gets too hot during use. When this occurs, the wire may short or stop feeding correctly. A temporary fix is to bypass the damaged section by attaching a wire externally (a "jerry-rigged" connection) to restore conductivity. You can also test by jumping the connection at the plug; if it starts working, the internal wire is likely damaged and needs repair.
