4 Only Aluminium Welding Rods 3.2mm x 350mm long Rods
HARRIS ALUMINIUM DC ARC WELDING ELECTRODES
* 4 Only 3.2mm x 350mm Long Flux coated electrodes.
* ALUMINIUM DC MMA WELDING Electrode
*....4 Only 3.2mm x 350mm Long Flux coated electrodes.
*....Universal electrode for welding all cast, wrought and extruded aluminium and aluminium alloys in all positions. *....AWS A5 E 4043
*....Flux Coated electrode providing high speed deposition of dense, machinable welds.
*....Use for fabrication and repair of cast & wrought aluminium, foundry defects, machining errors and salvage work.
*....Ideal for repairs and maintenance.
*....(DC reverse current only).
*....Suggested Amperages 83-135 Amps
*....(They can also be used with a conventional oxy-acetylene torch for gas welding aluminium!)
INSTRUCTIONS as per J.W.HARRIS Co Inc.
3.2mm x 350mm Long Aluminium Electrode (83-135 amps)
* Use Dc reverse polarity only.
* Weld area must be clean and heavier sections should be Vee d or bevelled.
* Preheat heavier (over 6.0mm) sections to 500 F.
* Hold electrode at right angle to work and tilt electrode slightly in direction of travel.
* Slag is easily removable and should be chipped or brushed between passes.
* Tensile strength up to 34,000 Psi
* Extruded Thermo Coating Aluminium alloy for low temperature Arc Welding of all weldable Aluminium s.
*....My own observations are the Electrode are hard to start, and extremely current / amperage sensitive. (Getting the right setting may take time?)
*....Once the arc is started maintain a short arc keeping the electrode within the slag cover, travel is similar to welding with mild steel.
*....Weld appearance will improve with operator experience.
