(1)45 to 75º downhill position is recommended for easy welding and fast speeds. Corner welds on 10 gauge steel can be welded 5-7 in./min. faster when positioned 75 to 90º downhill rather than 45 to 75º downhill.

(2)For AC welding use:

a.E6011 in place of E6010 or E6013 in place of E6012

b.The same electrode diameters.

c.About 10% higher current.

d.The following arc speeds:
