CHAPTER 5. OPERATING INSTRUCTIONS
HF28 DC RESISTANCE WELDING SYSTEM

11. Try making welds with only one part present. Also try making welds with misaligned parts.
Observe that the power supply terminates the weld during the first pulse as soon as the voltage
limits are reached. If the voltage limits are not being reached with these conditions present,
return to the voltage monitor screen and adjust the limits accordingly. You may also have to
adjust the Pulse 1 current from the RUN screen if needed to optimize the Pre-Weld Check
settings.
12. The Pre-Weld Check function can now
be used to detect misaligned or missing
parts before the Pulse 2 welding current
is delivered to the parts.
