MAINTENANCE 

SOLDERING TIP PREPARATION

•  Keep the soldering tip properly tinned.  Always use solder with 

sufficient rosin flux or the tip will de-wet. A well tinned tip will be bright 

all over when hot, with no dull or discolored spots.

•  To tin the soldering iron tip:

1.  Plug in the iron and allow it to reach solder melt temperature.

2.  Flood the tip with solder and let it stand for one minute.

3.  Apply more solder to the tip, allow it to idle for one or two more 

minutes, wipe it lightly on the sponge.  Do not remove all of the 

solder, but use the sponge to remove excess solder and wipe 

solder onto non-tinned areas.

•  Do not file or attempt to reshape the tip. This will destroy the plating 

and shorten tip life. Do not use chloride and acid fluxes; they will also 

shorten tip and heater life.

•  For maximum tip life, always apply solder to the heated connections 

or joints. Repeated application of solder directly to the tip will shorten 

the tip life.

WARNING:  Do NOT use anti-seize or any other lubricant on the tip 

retainer or heater of the soldering iron.

UNIT

1.  Keep the unit plugged into a GROUNDED outlet at all times during 

operation.

2.  Keep the unit and all components free from dirt, debris, and liquid 

at all times.

3.  Make sure the power cord is plugged in correctly and safely off the 

floor to prevent accidents.

4.  Keep all cords in the immediate workspace and avoid letting them 

hang off the side of a table or bench top.

5.  Wipe the unit down, when needed, with a dry, static-free cloth.
