Advancements
in Technology of Soldering Equipment
Along
with an increase in the melting points of the
new alloys, advancements in the way that hand
soldering tools perform, are critical as well.
The requirement to transfer heat to the application
without significantly increasing the working temperature
of the soldering tool being used can only be achieved
by increasing the thermal capacity of the tool.

An increase in the thermal capacity accompanied
by the direct transfer of energy from the soldering
iron’s heating element to the tip, is how
Weller has overcome the challenge of hand soldering
for the industries growing needs. With one of
the market’s highest wattage electronically
controlled soldering irons, which boast an impressive
output of 80 Watts, the Weller Silver Series Model
WSD81 Soldering tool meets the stringent demands
for the new alloys.
For applications that require more precise soldering
techniques, the Weller Silver Series Models WSL
and WSL2 combine to offer one of the closest “Tip
to Grip” handle designs (37 mm / 1.46”
Tip Reach) on the market. Along with 65 Watts
of continuous, controlled power, the Weller WMP
Model soldering iron offers an additional option
to the future of Lead Free soldering task.
With the added features of Temperature “Lockout”
for process control, Auto “Setback”
and Auto “Off” for improving tip life,
°F to °C conversion capabilities, the
Weller Silver Series products offer the latest
advantages to hand soldering equipment.
All Weller Electronic soldering products meet
or exceed the stringent requirements for EOS (Electrical
Over Stress) and ESD (Electro Static Dissipative)
standards, as well as all applicable MIL-STD and
J-STD requirements (2 mV TRMS, 2 Ohms Tip to Ground
Resistance, etc.).
Advancements
in Technology of Soldering Tips
Due to the nature of the higher Tin (Sn)
content of the Lead Free alloys, advancements
in soldering iron tip technologies also must change.
It has been determined that the higher Tin content
may cause a shorter life expectancy on soldering
tips because of the fact that Iron (Fe) plating
is used as the protective covering (commonly referred
to as Electroplating) on all electronic grade-soldering
tips. Iron (Fe) “migrates” or “leaches”
more quickly into the higher Tin (Sn) content
of the Lead Free alloys as opposed to the previously
used Tin (Sn) / Lead (PB) solders that have been
used for decades. Due to this phenomena, an increase
in the thickness of Iron (Fe) applied to the soldering
tips is the only known way to improve tip life.
