Do not quench the joint with water and do not force the cooling, too fast a cooling rate leaves too much ferrite in the weld. Match the drive rolls to the wire diameter and check the liner, wire slip shows up at once in an unstable arc. Watch the wire stick-out from the contact tip, too long a one lowers the arc voltage and worsens the fusion.
