Started practicing on welding up holes with the TIG, did 5 practice holes, before starting on bed sides ( this hole is on the inside lip of the bed top rail). Used the pure copper strip to block the bottom of the hole to be filled ( needs to be 1/8 inch thick). Clamped in place. Then slowly did spot welds around the outside of the hole, skipping space between welds, then another spot weld. Backed off amperage some ( not all the way) between welds, to let it cool then another spot weld. Slowly filled the hole. Ground the welded up hole some, needs more in last two photos. The hole area is recessed some so over welded the area a little, will add some body filler later.
