Masterweld ER4043 aluminium arc welding rods can be used for welding many different grades of aluminium alloys, either to themselves or for dissimilar welding applications to different grades of aluminium, whether cast, wrought and extruded aluminium.

Masterweld E4043 is an all-positional aluminium arc welding rod.

Ideal for situations where TIG or MIG welding of aluminium is not possible. Being a manual metal arc welding rod this obviously doesn't require any shielding gas which is ideal for applications where gas maybe isn't available, or can't be used due to weather conditions on site.

  • Very smooth metal transfer
  • Run on DC (AC has to be used in TIG welding)
  • Unique self lifting slag
  • Excellent weld appearance with bright finish
  • Specially extruded flux coating for long shelf life
  • sealed packaging - excellent for on site applications

Best welding techniques for arc welding Aluminium

Remove oil and grease and wire brush or sand/grind the immediate weld area. Chamfer the edges of the plates to be joined and open up cracks. Make holes to be filled wider at the top. Pre-heat heavy sections broadly. In thick-to-thin joining, preheat the the thicker material. This aluminium welding rod will run from any DC arc welding machine including engine driven welder generators. Adjust for the upper end of the recommended amperage range and reduce the amperage as welding progresses and the aluminium base material starts to absorb the heat. Burn the aluminium arc welding rod quickly and move relatively fast. When picking up each bead, welding into the previous crater before continuing.

Typical aluminium welding applications

Truck beds, bodies and frames, loading ramps and docks, pipe railings, bannisters, stairs, diamond plate, door and window frames and supports, irrigation piping, transmission housings, gear boxes, engine and motor blocks, machine bases and supports, bus bars, electrical switch boxes and mounts.
