CHAPTER 5. OPERATING INSTRUCTIONS
HF-2500A HIGH FREQUENCY WELD CONTROL
5-2 990-371
Initial Setup
1. Adjust the weld head force adjustment knob for a force appropriate for your welding application.
A good starting point is the mid-point in the range of the weld head force.
2. Set the WELD/NO WELD switch on the Power Supply front panel to the NO WELD position. In
this position, the Power Supply will operate the weld head without producing weld energy.
NOTE: When you are ready to perform a weld, be sure to set this switch back to the WELD
position.
3. Turn the ON/OFF switch on the rear panel of the Power Supply to the ON position. The default
RUN screen will be displayed. You will use this screen to enter welding parameters.
