EN 573-3: E AlSi12
DIN 1732: EL-Al Si12

FEATURES & APPLICATIONS

For arc welding aluminums alloyed with copper, silicon, and magnesium.
Also excellent for joining dissimilar grades of aluminum.
12% Silicon aluminum arc welding electrode with exclusive self lifting slag. Other aluminum grades such as Al 99, Al Mn, etc. are also available.
Unique self lifting slag.
Pure white long shelf life extruded flux coating outlasts conventional products in moisture resistance.
Can be manufactured in a variety of custom colors.
Available in hermetically sealed PURE ALUMINUM pull ring cans or vacuum packed foil bags for extended shelf life.
Also available in TIG form as item code 6047, in MIG form as item code 7091 and as a bare torch brazing alloy as item code 2191.

Welding Current & Instructions

Recommended Current: DC Reverse (+)

Diameter (mm)	3/32 (2.5)	1/8 (3.25)	5/32 (40)
Minimum Amperage	50	70	110
Maximum Amperage	80	120	150

Welding Techniques: Start by using the upper portion of the amperage range. Feed the electrode quickly and move fast maintaining a very close arc gap.
Welding Positions: Flat, Horizontal
