MODEL HF2 2 kHz HIGH FREQUENCY RESISTANCE WELDING POWER SUPPLY990-057 2-1CHAPTER 2GENERAL SET-UPREQUIRED CONNECTIONSPhysical Space RequirementsUnitek Peco recommends that the HF2 Weld Control and HF2 Weld Transformer be installed in a wellventilated area that is free from excessive dust, acids, corrosive gases, salt and moisture. Allowsufficient clearance around both sides and back of the HF2 Weld Control and HF2 Weld Transformer sothat cooling air may flow properly. Figure 2-1 shows the cooling airflow pattern for the HF2 WeldControl. Figure 2-2 shows the cooling airflow pattern for the HF2 Weld Transformer.Figure 2-1. HF2 Weld ControlAir Flow PatternFigure 2-2.
