Hobart electrode packaging is color coded for easy identification of electrode grade and has the electrode size prominently displayed when applicable.
line
Stainless Steel Electrodes, 308L

 For 308 and 304 stainless base metal. Smooth, tough welds with the strength, corrosion and crack resistance needed for welding stainless steel in all positions. Easy slag removal. AC or DC electrode positive (reverse) polarity.

Size Part No. Qty.
3/32" #H481930-RDP 5
1/8" #H481944-RDP 5

line
Stainless 312 Plus Electrodes

 For hard-to-weld or dissimilar metals, stainless, high-carbon, cast, and high-nickel steels. All-position, AC/DC (electrode positive), easy strike and re-strike, high moisture
resistance, self-detaching slag.

Size Part No. Qty.
1/8" #H480644-RDP 5
line
Aluminum Electrodes, 4043

 Aluminum welding for flat, horizontal and vertical applications. DC (electrode positive) only.

Size Part No. Qty.
1/8" #H722844-RDP 10
line
Nickel 55 Electrodes
For repair in all positions of materials with 55%-nickel cast iron. This electrode produces welds with higher strengths and ductility than the straight nickel electrodes. Deposits are machinable, but harder and more resistant to cracks and abrasion than high-nickel welds. AC/DC (electrode positive). Preheating is mandatory on cast iron.

Size Part No. Qty.
3/32" #H500631-RDP 10
1/8" #H500644-RDP 4
line
Nickel 99 Electrodes
This high-nickel-content electrode is good for castings of light to medium weight. Welds are easily produced in all positions and the deposits are readily machined. AC/DC (electrode positive). Preheating is mandatory. Cool slowly in still air.

Size Part No. Qty.
3/32" #H500531-RDP 10
line
Hard Surfacing Electrodes, Overlay
High-chromium manganese-alloy electrode used for buildup and overlay. Used for austenitic, carbon and low-alloy steel. Excellent impact resistance, good abrasion resistance and improved corrosion resistance. AC/DC (electrode positive preferred). For 1/2" to 3/4" base materials. Preheat to 200° F and cool slowly.

Size Part No. Qty.
1/8" #H544051-RDP 4
line
Hard Surfacing Electrodes, Build Up
High-chromium carbide-alloy steel electrode used for buildup on carbon, low-alloy or austenitic manganese metals. Excellent abrasion resistance, good impact and improved corrosion resistance. AC/DC (electrode positive preferred). For 1/2" to 3/4" base materials, preheat to 200° F and cool slowly.

Size Part No. Qty.
1/8" #H542144-RDP 4
line
Cutting/Chamfering Electrodes
For cutting, beveling, or gouging of all metals and removal of weld joint overlays or other unwanted materials. All-position, AC/DC (electrode positive).

Size Part No. Qty.
3/32" #H990001-RDP 4
line
Nomacast Electrodes
For various grades of cast iron, this electrode provides an excellent, non-machinable base pass for subsequent nickel alloy repairs on contaminated cast iron. AC/DC (electrode positive preferred).

Size Part No. Qty.
1/8" #H990003-RDP 14
