remember steve wont see the welder it comes direct from tec arc send him a pm hes it not allways on here a busy manGuess so, I made one from one of those round plastic cases you get 20 blank cd's in, just cut two holes and a hole for the drive lug. It will do until I can get some of the proper spacers (they should have come with the machine if it was unmodified) but not what I expected from the reputation Steve has on here. to be honest he may have been informed that they had been modified after a certain date and ours managed to slip through prior to that, but would have expected some sort of explanation rather than "plug it in and weld" which wasn't helpful as I couldn't!
Reading this thred with interest have had a 185 about a month now same spool as one in your pictures.
Never had a go with a 5kg reel just 15 .but going to try one .if it works fine but if not will be getting on to tec arc .don't think its on to advertise machine as ok with both sizes and then tell you after purchase that you will need adapter set
