Model RT-175 Electric Soldering Gun
Figure 9 – Cleaning Threaded Stud
3. Clean threads of the threaded stud with a wire
brush to ensure good contact with the new carbon
tips (Figure 9). Burned threaded studs will not pro-
duce good contact and will not heat properly.
Replacement threaded studs are also available if
they are damaged.
4. Never apply torque to the insulated handles because
you can crack the plastic material.

Maintenance
WARNING
Make sure unit is unplugged from power source

thing “finger tight”.

They should be inspected before each use and replaced
before the threaded studs begin to show through.

2. Hold the lock nut and back-off the carbon tip by turn-
ing it counter-clockwise (Figure 8).
