Sounds like you are getting the high frequency starting arc but not the power. I know that if I am stick welding and I have the high freq on, the the high freq arcs will jump between the electrode and ground but the power arc won't start until I get the stick electrode closer to the workpiece. When I get about 1/4" from the workpiece the power arc will jump. Perhaps you have a bad welding lead connection/bad ground or the voltage output is too low?
