15 Electrode

Rapid Cutting Action

The superior metal removing ability of 15 results from the melting reaction of its special coating and special core wire which produces hydrated oxides of iron, silicone, titanium, and aluminum. These oxides release super heated gases which not only melt the base metal but are released with such velocity that they blast the melted metal away.

The coating is of an exothermic nature and contains a blend of finely pulverized special heat resisting ceramic constituents. This special coating contributes to the exothermic reaction by the fact that it has been designed to increase heat and blast. The ceramic constituents in the coating melt slower than the core wire and this forms a cup at the electrode tip. This cup serves as a crucible and supports the continuous thermic re-action.

Versatility

15 can be used for cutting all metals, piercing holes, bevelling, partial machining, and in general for practically all metal removing applications. Precision cuts can be made using a template of asbestos or heat resisting board.

Specific Applications

• Cutting stainless steel
• Cutting cast iron
• Cutting foundry scrap
• Removing foundry gates and risers
• Removing rivets
• Piercing bolt holes in structural steel
• Bevelling cracks prior to welding
• Removing old welds
• Cutting hard-surfacing deposits
• Cutting pipes with water in them
• Cutting plug welding holes

How to Use

For DC equipment use straight polarity (electrode negative). This electrode performs equally well with AC current. For cutting or piercing heavy or thick metals, higher amperages are used. For thin metal, lower amperages are used. The special coating will accept a high current and the electrode will become more efficient at high current settings.

For Cutting

The electrode is used in a saw-like motion, being inserted up and down in the direction of travel to actually melt the metal and punch it out, leaving a clean cut. Do not hold the electrode top entirely above the metal being cut as with torch cutting, but actually travel along piercing the electrode up and down with a saw-like motion. When cutting thin metal, use the 1/8" electrode, for medium the 5/32". No "drips" or cutting residue adheres to the base metal as occurs when cutting with a carbon stick.

For Piercing or Holing

For piercing, the arc is struck where the hole is desired and it is jabbed in and out until it has actually pneetrated all the way through the object being pierced. 15 will not snuff out when piercing a hole as an ordinary electrode will. The coating is a non-conductor and will not side arc. A large hole can be made by oscillation once the base metal has been pierced.

For chamfering

For bevelling, the electrode should be held at a very low angle not to exceed 15 degrees from the work. It is then pushed ahead, actually penetrating one half of its diameter into the base metal. At this low angle the base metal is literally blasted away.

Economical Usage

15 is considered the lowest cost metal removing tool in existence. It can remove up to 65 lbs of unwanted metal per hour as compared to approximately 6 lbs per hour with a chipping gun.

With oxyacetylene torch cutting, the cost of fuel gases is approximately $12 per hour in most areas. When it is considered that the electric current required by 15 is only $.10 per hour in most areas, the saving in energy alone can be quite considerable.
