TIPS ON USING YOUR SOLDERING IRON

 

1.Select the proper solder for your application. Most solders sold today have the flux inside their cores. When makina electric or electronic connectionsalways use rosin core solder. For mechanical joining where the surfaces can be washed after Gldering acid core solder can be used. Common nonplumbing solder is an alloy of tin and lead. A "60-40" solder is 60% tin and 40% lead. General purposesolders range from 40-60 to 60-40.

63-37 solder has the lowest melting temperatureand highest strength. The diameter of the solder wire should generally match the slze of the componentsto be joined.

2.Be sure the surfaces to be joined are clean. Remove any oil or grease. Surfaces can be thoroughly cleaned by using abrasives such as emery cloth, steel wool or by scraping or filing. The flux in the solder will remove the oxide layers which could prevent good bonding.

NOTE: New units are shipped untinned. Remove plating at end of tip before tinning.

3.BE SURE THE TIP OF THE SOl.DERlNG IRON IS CLEAN AND,WELL TINNED (COATED WITH SOLDER). The solder on the ti0 of the iron w~llmelt raoldlv and create a conductive

path for thehkt to;&$ the work$ece. A small additional'ambuntof solder may be added to the tip while it is in contact with the workpiece to ensure good heat conduction.

4.If possible connect the workpieces mechanically, or positionthem as rigidly as possible.

5.Allow the soldering iron to heat sufficiently: 1 minute minimumto about 3 minutes for optimum operating temperature.

6.Apply the heated tip of the soldering iron directly to the work. Heat the work surfaces sufficientlv for the solder to melt on them. Aoolv the solder to the work surface directlv. Do not juit melt the solder on the tip of the irori allowingit to fall onto the work. This ' will cause poor bonding betweenthe solder and the surfaces to be joined. Remove the iron quickly after the solder flows on the work surfaces.
