Average Value Pulsing In The Vertical-Up Position (Pf) - EWM Tetrix 351 AC/DC Synergic FW Operating Instructions Manual

5.4.8

Average value pulsing in the vertical-up position (PF)

Welding characteristics:
•
Especially suitable for root welding
•
Fine-flaked weld surface with a TIG look for final passes
•
Less finishing work thanks to less spatter
•
Highly suitable for difficult electrodes
•
Outstanding gap bridging with no sagging of the root side
• Less distortion thanks to controlled heat input
