What length leads seem to meet your requirements? We've got one set-up with 80' ground & 100' work and rarely do we reel the whole length out unless someone is too lazy to get a little closer. I've been keeping an eye on prices to get another welder ready for service and methinks I'll be laying out quite a few frogskins......
I carry 125' of lead and 100' of ground. I can park on one end of an oil rig or a flat tank and reach the whole thing with room to spare. I keep extensions of varying lengths in the garage but its rare that I have to break those out.
I got it broke down in 100' section with quick connects I don't use that much all the time but some time I get on a bridge over water and the only way to get to what I got to weld is from eact end.
i've got 100' on each side w 100' of cord and 125' of torch hose i have another 200 ' of lead i keep at the house until i need it i use that for repairing derricks that sre standing
400' divy up how u like, 150 oxy/acet, 250' powercord have had no problems reaching anything so far. i have 100' roll, then all else in 50' lengths. hope it helps.
