High voltage on tip.
3.1 Check resistance from pin 5 of the tool connector to tip, should measure 2 ohms maximum.

3.1.1

If tip ground is open, remove heater/sensor assembly and check continuity of ground wire in cord.

3.1.2

Repair wiring as required, else replace cord/handle assembly if open.

Weller

ET and SMT series tips are solid Copper, plated with Iron, Nickel and Chromium. The Nickel and Chromium protect the

shank from corrosion and solder creep. The tips are pre-tinned in the working area with solder. Use only Weller

soldering tips. Use

of non-Weller

components may void product warranty if the non-Weller

component causes damage to the unit. Consult tool and tip

selection sheet for available tip styles.

1. Keep tip tinned; wipe only before using.
2. Use rosin or activated rosin fluxes. Acid type fluxes will greatly reduce tip life.
3. Remove tip and clean with suitable cleaner for flux used. The frequency of cleaning will depend on the type of work and

usage. Tips in constant use should be removed and cleaned at least once a week. Corrosion between tip and sensor can

cause erratic temperature control. WARNING: If tip does not remove easily, do not force it. The sensor will be damaged.

Try removing the tip while heated. If this does not work, return tool to Weller

for service. When installing new tips, they

should slide freely over sensor probe.

4. Dont try to clean tip with abrasive materials other then the Weller

WPB1 polishing bar and never file tip; to do so will

greatly reduce tip life. Tip wettability is affected by contact with organics; such as plastic resins silicone grease, and other

chemicals. If the tip becomes unwettable, it may be cleaned hot with a soft steel or brass brush using solder flux as a

solvent; or with a Weller

WPB1 polishing bar. Do not over do this or the iron plating will be removed and the tip ruined. Re-

tin tip immediately after cleaning to prevent oxidation.

5. Do not remove excess solder from heated tip before storing. The excess solder will prevent oxidation of the wettable

surface when tip is re-heated.

6. Do not use any compound or anti-seize material on Weller

tips or sensor probe. This may cause wettability problems and

may cause seizing after extended heating periods.

Use the soldering tool only with the specified voltage or specified pressure and pressure range.
