MMA pulsed welding 

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
