I just purchased a Lincoln Power Mig welder model 140C that Lincoln advertises as follows: “Wide 30-140 amp welding output range is the highest output in 120 volt input power welder class.â€
In the operator's manual the requirement for the advertised maximum output states: "In order to utilize the maximum output capability of the machine, a branch circuit capable of 25 amps at 120 volts, 60 Hertz is required". The manual also states the recommended input fuse size is a 20 amp breaker and recommended input amps are 20.
The design of the Power Mig 140C type 5-15P power cord input does not provide for 25 amps at 120 volts because no 25 amp receptacle exists where a type 5-15P power cord will plug into it. However it will plug into a 20 amp receptacle. It's not possible to obtain a 25 amp breaker or a 25 amp (or larger amperage) receptacle that matches the 5-15P power cord. Beyond 20 amps a 30 amp circuit is the next highest circuit according to industry practice.
I certainly would appreciate any suggestions or insight in how to safely and legally obtain the advertised maximum output of my new welder without modifying the welder's NEMA Type 5-15P power cord.
