SAFETY PRECAUTIONS

The Weller

D650 Soldering Gun is a very safe tool. It is UL listed and com-

plies with all the relevant safety regulations in the USA. Nevertheless, like all

electrical appliances, it must be handled with proper care. Never forget that the

operating tip of the Industrial Soldering Gun reaches high temperatures.

Follow these safety rules at all times:

1. Keep your soldering gun well away from all flammable material.

2. To avoid burns, always assume that the tip is hot.

3. Be sure the hot metal tip does not come into contact with the electric

power cord.

4. Before making any adjustment - removing or replacing a tip etc. -

make sure the gun is unplugged and cool.

5. Release the trigger whenever the tip is not in contact with work.

NEVER tape back the trigger.

6. Do not hold work in your hand if you can possibly avoid it. Us a vise,

clamp or pliers.

7. Do not dip the tool into any liquid.

8. Many materials give off unpleasant or possibly toxic fumes when

heated - so ALWAYS work in a well ventilated room.

9. Clean the tip by wiping it, when hot, across a damp soldering tool

sponge - placed on a non-flammable surface, NOT held in the hand.

Immediately re-tin the tip with solder after wiping it on a damp sponge.

This prevents the tip from oxidizing and provides a better means of

heat transfer. (See directions below on how to re-tin tips).

10. After use, disconnect the soldering gun, allow the tip to cool

completely, and store the tool in a safe place (out of reach from

children).

11. Always wear safety goggles to prevent hot materials from entering

eyes.

12. Never attempt to use, or even plug in the gun if the power cord or

plastic housing is damaged in any way.

13. When handling the gun, always grip the gun by the handle. Do not

carry the unit by the power cord.

14. Your D650 is equipped with a three prong power plug. Do not remove

the grounding pin. Do not use 2 prong converter plugs.

CARE AND MAINTENANCE

The D650 soldering gun needs very little in the way of care and maintenance to

keep it in first class condition. Occasionally, the soldering tip needs re-tinning.

Also, other tips can be used for different applications.

RE-TINNING TIPS

If the solder doesnt cling to the work tip and instead of flowing smoothly, rolls

off in small globules, the tip probably needs re-tinning. The following steps

explain how to re-tin a tip.

1. While the tip is cool, scrape the wettable area of the tip with very fine

sandpaper or steel wool..

2. Depress the trigger and apply solder to the tip until it starts to melt.

3. Keep the tip in contact with the solder.

4. After 3 or 4 seconds, release the trigger, but continue to apply solder until

the tip cools.

5. Once heated, wipe off any excess solder, but re-apply a small amount

before continuing.

6. The tip should now be thoroughly tinned. If it is not, repeat the procedure

starting with Step 1.

REPLACING TIPS:

Weller

has been producing soldering guns since 1945. During that time there

have been two styles of tip attachments.

STYLE 1

Replacement tips can be purchased with or without threaded studs. If you

purchased tips only (Replacement Part # 7250W), and plan to use the

threaded studs that came with your soldering gun, then follow the entire

procedure below. However, if you purchased a replacement tip complete with

threaded studs (Replacement part # 7250N), then skip Step 3.

1. Ensure tip fastening nuts are placed on new tip as shown.

2. Insert tip ends into side holes approximately 6 mm or 1/4" and pull

forward to start bend.

3. Insert tip ends through barrel opening and into side holes.

4. Carefully start nuts by hand and after threads take hold complete

tightening with a wrench until secure. Important: Snug tip nuts are

necessary to provide a good electrical connection. Loose tip

nuts can cause soldering gun to not heat properly.
