Another spot welding ???

Yes I tried that , even replaced the tips and cleaned out the probe ends. I also took off the cable ends at the transformer and cleaned that connection as well and still no change. I really think that the transformer is wore out . I really would like to see some sample pieces that owners of these units have done. I am sold on the idea of same side spot welding , but just don't have the confidence in my current unit to invest in a new one. Please post pictures if you have them. Thanks :thumleft:
