Thinking of getting a longer mig gun for my Lincoln SP250. Would like a 20 or 25ft gun. Just wondering if anyone has experience with running a longer gun off a 250 amp lincoln, miller, esab etc? did you find it sucessful or did it overpower the motor resulting in slipping, varying wire feed speeds etc.
I know that keeping it relatively straight will help and the correct liner size will be paramount.
I am sure my 4 roll ESAB 300AVS would handle it no problem. however as that is a suitcase there is no real point to having a long gun on that.
current gun is a 12.5 ft gun. I have ordered a spare 4 wire Euro plug for my machine off ebay so I will just have to adapt the back end of whatever gun I get to fit. Also would just do the Centerfire gun conversion like i did on the stock gun. Plan to get a 200 or 250 rated gun. Probably run it with .045 wire due to length. if its a short job I can just switch out to the standard torch I want to be able to leave the machine on the concrete part of my driveway that is only 2 slabs and often what I am welding will require more than 12.5' of cable. I installed a 25 ft ground already..
