- Set the temperature control knob to the minimum position and place the main power switch in
the "ON"-position.
- Set the temperature for 250°C (482°F).
- Coat the tinned surfaces with a layer of solder.
- Install the desired temperature after allowing the unit to idle at 250°C for three minutes.
- The station will be ready for use once the installed temperature is reached.
8. Loss of Suction : Possible Causes
Use the procedure outlined below to determine whether the loss of suction is due to the tip, to
the solder collector, the tube or the in-line filters.
CAUTION : THE MAIN POWER SWITCH SHOULD BE IN THE "OFF"-POSITION BEFORE
ATTEMPTING THESE PROCEDURES. THIS WILL ALLOW THE DEVICE TO
COOL.
a) disconnect the vacuum tube from the fitting on the front panel. Place your finger over the hole
and depress the vacuum switch. You should now have a strong vacuum. If not : return the
station to the point of sale to have the pump repaired.
b) disconnect the in-line filters from the iron assembly. Depress the vacuum switch, replace the
filling of the in-line filters if there is little suction or if the filters are discoloured.
c) Remove the solder collector from the desoldering iron assembly, place your finger over the
hole and depress the vacuum switch. Clean or replace the collector tube in case of
insufficient suction.
d) Depress the vacuum switch and clean the tip with the included spring wire if there is no
suction. Read "
10. Cleaning Procedure for Clogged Tips
".
9. Maintenance
Desoldering tips can be replaced simply by unscrewing the barrel nut assembly. Turn off the
station and allow it to cool first. Damage to the soldering station may occur if the system is left
on and the removed tip has not been replaced.
After removing the tip, you should blow out any oxide dust that may have formed in the tip
receptacle. Be careful not to get dust in your eyes. Replace the tip and tighten the screw. Pliers
can be used to avoid contact with hot surfaces BUT SHOULD BE USED WITH CAUTION
because overtightening may cause damage to the element or fuse the tip to the element.
10. Cleaning Procedure for Clogged Tips
CAUTION : BE VERY CAREFUL NOT TO BURN YOUR FINGERS WHEN CLEANING THE
TIP.
1. Move the spring wire (included) back and forth in order to clean the tip.
2. Raise the temperature of the heating element to allow the clogged solder to melt. Clean the
tip by sliding the spring wire up and down until the passage is clear (see fig. 1)
3. Unscrew the barrel nut assembly (fig. 2 & 3).
4. Use a pair of pliers to remove the tip (fig. 4 & 5).
5. Reinsert the stainless tube in the heating element to melt the solder, as shown in fig. 6. This
will take approximately 5 seconds.
6. Remove the stainless tube and shake loose the molten solder. The tip should now be
unclogged (fig. 7). Put the tip back in place and screw down the barrel nut assembly. Do not
screw it down too tightly !
