ZENA® NO-Gastm All Aluminum Arc Welding Rods
Use Your DC Arc Welder to Weld Aluminum


Now you can weld aluminum anywhere you can arc weld, even in poor conditions, without the need for a MIG or TIG torch, special welding wire, hoses, regulators, or expensive and heavy gas bottles.

These unique aluminum alloy welding rods let you use your DC arc welder to weld and fill all cast, wrought and extruded aluminum and aluminum alloys, working in all positions, with a high quality high tensile strength (34,000 lb. / 18% elongation) aluminum alloy using only your arc welder!

They can also be used with a conventional oxyacetylene torch for gas welding aluminum!

These special aluminum welding rods are perfect for welding, repairing cracks, and building up missing sections of:

Aluminum sheet metal

Truck beds, bodies, and frames,

Loading ramps and docks,

Engine and motor blocks,

Machine bases and supports,

Pipe railings, banisters, stairs, diamond plate,

Transmission housings and gear boxes,

Irrigation piping,

Bus bars, electrical switch boxes and mounts. 


Highly versatile, smooth running, easy-to-handle, all position Aluminum alloy arc/torch welding electrode for welding or filling low alloy Aluminum including aluminums alloyed with copper, silicon, and magnesium. Also excellent for joining dissimilar grades of Aluminum

1/8" (28 rods/lb)

Product Features:

Universal electrode for arc welding all cast, wrought and extruded aluminum and aluminum alloys in all positions.

Also excellent for joining dissimilar grades of Aluminum and Aluminums alloyed with copper, silicon, and magnesium.

Typical Applications:

Truck body/frame repair/fabrication

Cafeteria equipment repair/fabrication

Loading ramps/dock repair/fabrication

Engine and motor blocks/cylinder head repair

Repair and fabrication of machine bases and supports

Repair and fabrication of pipe railings, banisters, stairs, diamond plate

Transmission housings and gear box repair/fabrication

Repair and fabrication of irrigation piping, mixers, paddles, vats,

Repair and fabrication of electrical bus bars, electrical switch boxes. and mounts

Recommended Welding Techniques:

OK for welding in flat, horizontal and vertical applications.

Clean weld area by removing oil and grease and by wire brushing and/or sanding/grinding the immediate weld area just prior to welding. Chamfer edges of plated to be joined and open up/chamfer cracks and/or holes to be filled. Preheat heavy sections broadly. In thick to thin joining, preheat heavier member. For multi-pass work, it might be necessary to reduce amperage setting as base metal increases in temperature.

A close arc should be maintained. Feed electrode quickly and move fast. When picking up each bead, weld into the previous crater before continuing.

Upon cooling, slag/flux can easily be removed by chipping/brushing/sanding/grinding.

Expect best results using motor driven welding equipment with generators with DC rectified DC output.

Not for use with AC Arc Welders.
