Eastwood Company 59105 Blue Demon ER4043 Aluminum TIG Welding Rod 1/8" x 36" 10 lb Box

Blue Demon ER4043 is a general purpose aluminum welding rod that is one of the oldest and most widely used welding and brazing alloys. This aluminum alloy contains silicon additives, which result in improved fluidity (wetting action) of the weld pool and also produces a weld less sensitive to cracking. The arc is stable and operates at low temperatures with a minimum of spatter and fuming.

Key Features:

• Produces strong, dense, and porosity-free welds on both production and maintenance applications
• Great choice when welding heat-treated aluminum parts
• Bright weld finish makes it a popular choice of welders
• Can be run in all positions - flat, vertical, horizontal, and overhead
• May also be used in brazing applications
• Each rod measures 1/8 inch diameter by 36 inches long
• Packaged in a convenient 10 lb box for extended use

Typical Applications:

• Arc welding aluminums alloyed with copper, silicon and manganese
• Excellent for joining dissimilar grades of aluminum
• Welding filler wire and spray and flame metalizing wire

ER4043 runs optimally on ACEN polarity and requires a 100% Argon shielding gas for GTAW (Gas Tungsten Arc Welding, also known as TIG). Whether you're working on automotive fabrication, marine repairs, or general aluminum welding projects, this professional-grade filler rod delivers reliable performance and clean, attractive welds.
