Fast arc response with constant welding output
LINCOLN Electric designs, develops and
manufactures arc welding products, robotic
arc welding systems, fume control systems
and plasma and oxyfuel cutting equipment.
The company has launched the Power
Wave® R350, a robotic welding power source
with built-in robotic wire feeder control using
the latest inverter power technology to deliver
fast-arc response. Housed in a compact,
rugged case, the Power Wave R350 efficiently
converts input power to reduce operational
costs. The multi-process R350 can handle
GMAW (MIG), pulsed MIG and flux-cored
(FCAW) processes, as well as GTAW DC TIG
and pulsed DC TIG. Its Waveform Control
Technology® advanced process capabilities
include standard pulse, as well as Pulse-on-
Pulse®, Power Mode® and RapidArc®.
Its built-in wire feeder control provides
standard internal control for compatible
wire feeders, allowing users to modify
settings at the robot pendant. The modular
component design allows users to add a
Surface Tension Transfer® (STT) module
for arc control on thin sheet metal or critical
pipe welding applications.
Using Lincoln Electric’s patent-pending
PowerConnect™ technology, the Power
Wave R350 automatically adjusts to available
single or three phase 50 or 60Hz input power,
while maintaining a constant welding output
of five to 350 Amps throughout the entire
input voltage range (200-600 volts).
Through the use of Lincoln Electric’s
Production Monitoring™ 2.1 software,
users are able to track equipment usage,
store weld data and configure fault limits
to aid in production analysis and process
improvements. With the unit’s ArcLink® XT
communications protocol, easy software
updates and expansion can be processed
through a standard 100Mbps, full-duplex
Ethernet interface. The Ethernet capabilities
require no additional hardware or kit costs.
System costs are further reduced for
multi-arm applications, as multiple Power
Wave R350 units can be used together
without the addition of a separate network
Ethernet switch. No additional cards or
hardware are needed.
The Tribrid™ power module delivers
welding performance with high power
factor and efficiency for reduced electrical
consumption. The unit’s Intelligent
Architecture for Regulation and Control
(iARC®) high-speed, digital welding controls
are more than ten times faster than the
previous generation, offering 128 times
more RAM and eight times more flash
memory. Patent-pending Auxiliary Power
Surge Blocker™ technology ensures that
welding performance is not compromised
by simultaneous use of grinders and other
devices requiring high starting current (60A
or more peak surge current), using the
standard 115V (10A) AC duplex auxiliary
power receptacle.
The Power Wave R350’s durable case is
IP23 rated to withstand harsh environments,
having undergone testing in the most severe
conditions.
