Package increases control for pulsed arc welding

Fronius has developed the PMC (pulse multi control) pulse welding package for the TPS/i GMAW power source platform. It provides the welder with access to a variety of synergic characteristics that work with the company’s latest-generation devices. Features include an improved pulse correction function and an updated SynchroPulse welding process.

The newly developed penetration stabilizer function keeps fusion penetration at a constant level by adjusting the wire feed speed, even when there are stickout fluctuations, for example, in corners that are difficult to access or trajectory fluctuations in robotic welding. The arc length, and thus the fusion penetration, can be maintained at the same level over a large area to help simplify handling. The user can set and limit the value of the wire feed speed, which has been readjusted to the maximum extent, within a window of up to 32.8 ft.

The new arc length stabilizer function allows the user to influence the arc length directly via the welding voltage. The result is a short arc, meaning that short circuits occur, helping to ensure reliable droplet transfer. Quick control minimizes the duration of the short circuit and reduces the voltage at the right time, preventing bonding flaws and spatter. The user does not need to perform any manual readjustment in the case of external interference.
