Electrical wiring
The CP-300 and CP-200 were never designed to run on single phase. You can buy a 3-phase generator (see military surplus) or a phase converter.
You will need a pretty big one - like one rated for 20hp to use the full potential of the welder. That is also pretty expensive - say $1000.
However, if you have a shop, you can buy used 3-phase equipment sometimes significantly cheaper than 2-phase stuff. So you buy that expensive converter and save money on all the other equipment you will buy.
Or sell it.
Or scrap it - some older welders had big copper wound transformers - a few hundred bucks worth of copper.... some had aluminum though...
Good luck.

First thing to check is that you still have an inlet guide (plastic funnel like) before the drive rolls. This one can be dirty or have enough build up inside that makes the wire feed imposible. Change this one if possible, it will cost you around 5 bucks at your near welding shop. If everything looks ok, then make sure you have the right drive rolls size, 023 or 030 in this case. Then ckeck you liner if it has a kink or dirty in the inside (use compressed air to blow the inside of the gun) then it's useless, change it. Final will be the contact tip just replace it for the right size according to the wire size.
Hello,
I have had a mig welder for some time and
well theres a couple things it could be. first make sure the surface is clean. second check the type of metal the horseshoe's are made of. its really hard to get welding to stick to pot metal.
My lincoln 140 welds fine
You may be exceding the duty cycle of your welder
Check your operstors manual to see how long you can weld at higher amps before giving the welder a chance to cool down
