I'm wanting to replace the power cord on my Lincoln 175 Mig welder. When I bought the machine It had had a BIG bulky hard to move power cord and just plain a good eyesore,,,!! Do not know what wire size it now has but the OD on the power cord is 1 1/4" OD and very stiff to move around! I would like to install some smaller in size power cord that is more flexible. Any thoughts on this,,,,??

Use #6AWG SOOW cord for your input cord up to about 50' length for that size welding machine. Any smaller and you'll lose some top end performance and possibly weld quality. You could downsize to #8AWG but if you weld much over 125A the input cord will begin to warm up.
My assumptions are your welder is a 60% duty cycle single phase unit. If a 20% duty cycle unit, I wouldn't be afraid to downsize to #8AWG for the power cable as the welder will shut down before the input cable warms.
There are reasons that original cable is so heavy and it's not because the manufacturer wants to ensure they spend a bunch of money building the machine.

That welder only has a 20 - 25 amp input... But they "recommended" a 50 amp plug and wire when new... Thats a little odd.. An 8 gauge wire would be 40 amps. That should be fine as Codger says as long as the cord is not 50 ft long or your using 175 amps continuously !!
I just bought a "high flexible cable" for a smaller welder a month ago.. Bought over the internet at Home Depot of all places... see if i can find a link to a " flexible #8"..

The above cord is a STW which i think is a plastic cover.. Might get hard when COLD or 20 years old.... the SOOW that Codger talked about is rubber and should last forever.. Cost a little more.

SOOW is a very heavy EPDM jacket and if the welder in question is older, very well could be equipped with this. SJO is also very flexible but does not offer near the durability, or longevity of the SOOW but it is much lighter in physical weight. It is a PVC jacketed wire. SJO is typically what your outdoor extension cords are made from and we know how well that stands up to sunlight. Used continuously indoors wouldn't be a problem till a weld berry is dropped upon it.....
SJOW cable is smaller/lighter than SOOW and is weather rather for outdoor use, (the "W" stands for "weather, or outdoor" use) but is a bit difficult to source and used to be expensive.

Most units can also go with a reduced size ground wire . like 2 #6 and 1 #8 Now many units now use the 4 prong plug rather than the old 50 Amp range plug . Ran into that back in 90's when wife replaced her large studio KILN for ceramics . Had to change receptacles and buy a power cord .

OK, I don't understand having a 'reduced ground wire' size. If NEEDS to be same size as the power leads otherwise when machine shorts out, the smaller ground wire will fry and open up.
house 14/2 has 14 gauge ground wire.....

You are allowed to downsize one size on the grounds. I looked into this when built my building.
