trying to weld 0.9 with a clarke 150 te on the lowest settings, toiling to get a run so have to join the spots lol.. its using 0.8 wire, would 0.6 make a difference?
Usually a strip of copper bar or even flattened copper water pipe, you clamp it behind the weld area and it pulls some of the heat away as you weld reducing the risk of a blow through.the back strip part went over my head
I quite often use a length of flattened copper pipe, say 6 inches long and beat 4 inches flat. Then shove a wooden dowel in the unflattened part of the pipe to act as a handle cos the copper pipe gets hot rally quick!!. Then if needed bend the flattened end so that it can be held to the back of where you are going to weld. Note you wont want to do a very long run on thin sheet as the heat build up will burn through and/or distort the panel. Hardest part is getting the flattened part against the back of where you are about to weld. A good light behind helps and also putting a bit of tip dip on the copper stops it sticking.Thanks for the help , I’ve still a lot to learn and the back strip part went over my head. I’ll have a google the now. Cheers
not if your already on the lowest settingstrying to weld 0.9 with a clarke 150 te on the lowest settings, toiling to get a run so have to join the spots lol.. its using 0.8 wire, would 0.6 make a difference?
