#4 Welding Cable has 413 strands of copper. The large number of strands create less resistance since electric current travels on the surface of wire. This feature, coupled with the rope type design cause welding cable to be double flexible. The insulation is made of ethylene propylene rubber and is good for use to -40 degrees Fahrenheit. It offers super resistance to oil, grease and acid.

#4 Automotive Cable has approximately 45 strands of solid stiff copper wire. The insulation is generally neoprene, has little elasticity, and sometimes cracks under extremely cold conditions. Automotive cable has inferior flexibility characteristics.

First, any helmet you choose should meet ANSI Z87.1 standards, which ensure that helmets and lenses have passed independent testing to meet all safety requirements. Welding lens shade numbers refer to the lens’ ability to filter out light, and may range from a #8 shade for low-amp applications up to a #13 shade for high-amp applications.

A fixed (passive) lens helmet uses UV and IR coated dark tinted glass with a fixed shade value, usually #10. The welding helmet is worn in the up position while the electrode, gun or torch is positioned. With a quick nod or snap of the neck, the operator flips the helmet into position immediately before striking an arc.

An auto-darkening lens, in its inactive state, usually has a #3 or #4 shade, which is relatively easy to see through. When sensors on the helmet sense an arc start, the lens darkens, in a fraction of a second (typically 1/12,000 to 1/20,000 of a second for industrial grade helmets) to shade #8 to #13. Since the helmet remains in position before, during, and after the weld, an auto-darkening helmet enables you to set up your welding joint with the hood in position.

No more head snaps to lower the helmet. No more messy starts because the torch moved. No more raising and lowering the helmet for tack welds. This not only has the potential for improving weld quality, it can also help to ease the neck strain associated with snapping the helmet into place.

Welding Tips

Tips that are used for welding have a single hole in the end that directs the burning gas to the point that is being welded. A mixture of acetylene and oxygen is forced through this hole and ignited, causing a point of heat that is intense enough to cut through metal. Welding tips are manufactured in varying sizes, each one identified by a number. The higher the number, the larger the hole in the tip, and the thicker the metal it is able to cut. Welders need different sized tips. If they attempt to weld thin metal with an over-sized tip they will burn it, and if they attempt to weld thick metal with an undersized tip it will take too long to be efficient.

Cutting Tips

Cutting tips differ from welding tips in that the central hole in the end of the tip is surrounded by a series of smaller holes. The smaller holes serve as preheaters for the central oxygen flame that comes out of the central hole. As with welding tips, cutting tips are manufactured in different sizes to accommodate the gauge of metal that is being cut. To use a cutting torch, the operator applies the preheaters to the surface of the metal until it is got enough to glow red. He then activates the gas from the central cutting hole which removes the metal that has been weakened by extreme heat.
