I have been using a Clarke 135TE Turbo for quite a few years and apart from one issue caused by myself i have never ever had a wire feed issue. What you must do however if the wire feed stops for any reason whatsoever check the drive roller to make sure the wire has not bunched there. This is caused by burn back at the tip. Other than that good as gold.
Oh and i only ever use the 5kg reels of wire, the smaller 1kg ones do create a bit of a tight feed angle which may cause potential problems. However i use the 5kg reels on any welder i use or have used.
