I never had that issue. I usually kept the the rollers cranked down pretty tight. Never bothered by the length of the cables either, the welder is so small I just moved it to wherever I was working. On thing the is necessary is a long enough extension cord. I have a reasonable 14G e-cord that made moving the welder easier. So far I am liking the Clarke unit. Especially for the money, it really is quite a step up in power, quality, and versatility. I;m sure Miller/Lincoln/Hobart would be an even better machine, but let me get some more time in witht he Clarke and I will let you know how it does.
Oh, here is a thought, on the HF, disassemble the gun, takes about 1 minute...inside the liner near the bottom of the handle is a fiber wire cleaner. Ive found the wire does NOT like passing through this fiberous crap easily. I yanked mine out and it fed MUCH better. Might help you out.
