Figure 2-16.Compressed air/nitrogen heating tool.
The compressed air/nitrogen heating tool comes in two styles: ac or dc electrical power supplies. The
power requirements are listed in table 2-1 for both styles.
Table 2-1.Compressed Air/Nitrogen Heating Tool Power Requirements
Electrical Power, HT-900B
115 VAC, 50-400 Hz, single-phase, 7 Amps
Electrical Power, HT-920B
220 VAC, 50-400 Hz, single-phase, 3.5 Amps
Heat gun output temperature
80-200 psig, 4 SCFM (Dry and oil-free)
Refer to the operator's manual for safe operating procedures for the compressed air/nitrogen heating
tool. A brief summary of these procedures follows:
1. Push down and fully turn the air regulator knob counterclockwise. This is to ensure that the air
regulator is off.
2. Remove the dust cap from the air inlet nipple. The inlet nipple is what we connect the air or
nitrogen source line to.
If nitrogen is used, make sure that you are in a well-ventilated area. Using
nitrogen is a poorly ventilated area. Using nitrogen is a poorly ventilated area can
result in suffocation.
