SOLDERING ACTIVITIES: IMPORTANT NOTE
Do not use temperatures in excess of 410°C (770°F) for normal soldering and desoldering purposes. The device can
be used at higher temperatures for short periods of time. EXERCISE GREAT CAUTION WHEN DOING SO.
7. Common Causes for Tip Failure
- The temperature of the tip exceeds 410°C (770°F)
- The tip is not sufficiently tinned
- Wiping the tip on a surface with a high sulphur content or on a dirty or dry sponge
- Contact with organic or chemical substances such as plastic, resin, silicone and grease
- Impurities in the solder and/or a low tin content
8. Maintenance Tips for Tips
The soldering and desoldering irons use extremely high temperatures. Make sure that the unit is switched off for
maintenance purposes.
Remove the tip and clean it after heavy or moderate use. We recommend cleaning the tip daily if the station is used
frequently. Remove excess solder in the tip retaining assembly to prevent the tip from clogging.
The supplied soldering and desoldering tips are made of copper covered with a layer of iron. They will retain their
projected life span if used properly.
- Always tin the tip before returning it to the holder, prior to turning off the station or to storing it for long periods of
time. Wipe the tip on a wet sponge or use our tip cleaner (ref. VTSTC) before activating the device.
- Using excessive temperatures (more than 400°C or 750°F) will shorten the life span of the tip.
- Do not exercise excessive pressure on the tip while soldering and/or desoldering, as this may cause damage to
the tip.
- Never clean the tip with a file or with abrasive materials.
- Do not use flux containing chloride or acid. Use only resinous fluxes.
- If an oxide film has formed, you should remove it by buffing carefully with a 600-800 grit emery cloth or by using
isopropyl alcohol and consequently applying a new protective layer of solder.
- Place both temperature control switches in the minimum position and place the main power switch in the "ON"-
position.
- Set the temperature of the soldering tip for 250°C (482°F) and put the temperature control switch for the
desoldering tip in the minimum position. Apply a new protective layer of solder when the tip has reached 250°C
(482°F).
- 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.
IMPORTANT
Remove and clean the tip daily. Remove excess solder from the barrel nut assembly when installing a new tip,
otherwise the tip may be fused to the heating element or to the retaining assembly.
9. 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.
