The Fronius Upgraded TransSteel Pulse Series now includes the addition of the pulse function, making it possible to bypass the intermediate arc which is difficult to control and is prone to spatter. The resulting reduction in spattering leads to up to 70 percent less rework, the company says. The series includes the TransSteel 3000 Compact Pulse, 4000 Pulse, and 5000 Pulse. All necessary welding parameters can be set on the front panel. A USB can be connected to the rear of the power source to store all important data, including time and device-related data, but also the parameters used such as current, voltage, and wire speed.
