Power Section designed around high
speed switching modules
• Lincoln manufactures its own integrated modules,
which allows us to optimize each module for
reliability
and performance.
Designed to withstand extreme
environmental conditions
• All PC boards are trayed
and potted.
• The transformers and
chokes go through a
double dipped varnish
impregnation process.
• Harness connectors
are made with locking
pins and sealed with
electrical grease.
Designed with
Fan As Needed (FAN
TM ) Circuitry
• This reduces the amount of debris that gets drawn
into the machine by turning the fan off when it is
not needed.
• The fan turns on before components get too hot,
thus increasing life expectancy of the electronics.
• Reduces the power used during machine idle.

All electrical components are derated
for added reliability
• All electrical components are designed to operate at
voltages lower than their rated voltages and
temperatures below their rated temperatures.
Designed for stable operation
• Patented dual current transformers prevent
current imbalance.
• Active balancing technology is utilized for keeping
the voltages balanced under all conditions.
Control system utilizes common PC
boards and software
• Able to accommodate feature enhancements and
optimizations from other products for longer life of
the inverter.
Designed for protection if a fault occurs
• Thermal protection, misconnection protection,
secondary over-current protection, and primary
over-current protection are all standard in
inverter machines.
Reliability Testing
During Product Build
From initial design to product build, we ensure that every power source we release to a customer meets
our standards for reliability and efficiency.
The burn-in cycle is conducted to
ensure machine performance matches
Lincoln Electric requirements.
Dielectric tests provide evidence that
electrical insulation will withstand the
rigors of the welding environment.
Each Power Wave
machine is weld-tested.
