USING A MODIFIED PULSED ARC FOR EVEN BETTER WELDING RESULTS
With PMC, Fronius has modified the pulsed arc in such a way that you can achieve even better results during pulse welding when combined with the powerful new TPS/i power source platform. Newly developed and modified functions provide significantly more control over the arc. As a result, during gas shielded arc welding of steel, aluminium and chrome-nickel, there is hardly any spattering. Consistently good penetration is guaranteed, there is less undercutting and you can weld quicker and more cost effectively than ever before.
INTELLIGENT STABILIZERS FOR PENETRATION AND ARC LENGTH
Penetration stabilizer
An additional wire control keeps the current and penetration constant if the distance between the welding torch and the component changes. The arc becomes significantly more stable and the penetration is much more constant. On standard MIG/MAG devices without a penetration stabilizer, the welding current, and thereby the welding power, drops if the distance changes. If the penetration is insufficient, there may be a lack of fusion. If the penetration is too great, the weld seam may drop through on thin sheets, as the welding current increases.
Arc length stabilizer
The welding voltage can directly influence the arc length. The result is a short arc with which short circuits occur, guaranteeing safe droplet transfer that is not susceptible to interference. The rapid control keeps the short circuit duration to a minimum and reduces the voltage. The arc length stabilizer keeps the arc constantly short, ensuring the arc is stable. There is no need for the user to carry out manual readjustment in the event of external interference. Considerable time savings can be made here in terms of the number of jobs (programmed welding programs) needed for an application, especially for robotic welding.
