leading wire electrode
trailing wire electrode
active pulsed arc with droplet transfer
inactive pulsed arc (no droplet transfer)
standard arc
direction of welding
= welding current of leading power source
= welding current of trailing power source
High deposition efficiency, low distortion thanks to low thermal input and
high welding speeds
Large gap widths are possible
Big differences are possible between the two wirefeed speeds
steel applications
max. welding speeds
thin-sheet welding
