1.4 TAWERS 350A 60% Duty Pulse, 80% CV
TAWERS 350 Amp welding systems come standard with Embedded Arc Control (EAC) technology which eliminates the need for three separate control systems and fuses control of the robot, welder and servo wire feeder into a single physical unit.
This new controls breakthrough is contained entirely internal to the robot controller and is monitored by the TAWERS 64-bit main CPU. EAC technology controls not only the robot motion path and sequence commands, but simultaneously synchronizes the welding power supply waveform control and servo wire feeder response accordingly, to adjust and correct for dynamic changes in the welding process.
TAWERS with EAC technology goes far beyond conventional digital communication systems, delivering the first and only generation of fully software-controlled robotic welding solutions.
SP-MAG is a new welding process developed out of industry needs for a more versatile CV welding process. Where conventional and even high-end CV processes have tried to produce low-spatter, high-speed welds, they have missed the mark ultimately demanding lower amperage levels or slower welding speeds to achieve their goals. TAWERS has successfully met these challenges by bringing together the major benefits of Pulse and CV into one process SP-MAG
Ultra-low spatter levels
Low heat input
Low susceptibility to arc blow
Wide process windows across entire amperage range
Excellent thin material and gap handling capability
Spatter is the enemy of every company, big or small. The TAWERS solution takes aim at not only the arc physics that generate spatter, but also other factors that
directly impacts spatter generation. SP-MAG combined with advances in welding arc starting and ending have led to an extreme decrease in the amount of spatter generated during the entire welding process. Extensive testing has shown that a switch from conventional CV to SP-MAG could result in a savings of 100 to 150 lbs less wire purchased per arc.
Reduced or eliminated secondary cleanup operations saving manpower, floor space and limiting total work in process
Using a 100 kHz primary side high frequency inverter, TAWERS offers an extremely fast response, providing exceptionally precise, almost real time, and control of the welding arc.
10-5 sec (10 micro second) control and correction cycle
5X faster response than conventional feedback control circuits
Electronic reactor control makes special process inductance taps a thing of the past. Optimum current control during all phases of welding is now possible.
