Crimping


More acetylene cutting grinding and welding. TIG torch playing up again. I guess the water cooled wire has just seen too many days. I must look into acquiring a replacement. The object on the left is an attempt to draw the item I am whacking with the hammer and screw driver. If you imagine drilling a hole into the side of a bit of tube, your next imaginary task is to stick bare electric cable up the tube as far as the hole. You then smack the tube section housing the wire as flat as you can to crimp and hold the cable. Next you try and bend that flattened part into a U shape and stuff the whole lot back into the sheath of the electric cable. The main problem is that electric cable is constantly trying to pop back into its sheath. Anyway, I have done the final tamping and U shaping quite a few times, but there still seems to be enough crud built up in the hose to block the path every couple of hours of welding. Even so it is more economical than waiting for an air cooled torch to cool down after every two minutes of welding.
