Each cable is sequentially marked and resists grease, oil and water, abrasion, cut, tear or flame. Welders Supply has just the cables you need! In addition, several cables packed tightly together can also have a reduction in their ability to dissipate heat. Item sold by the foot O. Therefore, oversized cables may not be cost effective. Item sold by the foot O. Higher ambient temperatures can reduce their ability to dissipate heat into the surrounding environment, and thus reduce their ampacity.

Welding Cable • Cut by the Foot from $0.62/ft

25 welding leads

The fine copper strands give welding cable more flexibility than other types of electrical conductors and the insulating jacket is designed to hold up to repeated movement over rough surfaces. Generally as output levels decrease, duty cycle increases until 100% or continuous output. It is the percentage of a ten minute period that the power source can operate at a given output current level before exceeding its thermal limit i. However, if the diameter of cable is too small for the level of current flowing through it, then the cable will overheat. Resistant to chemicals, oils, and acids and is also weather, ozone and sunlight resistant. You use a smaller hose to water your garden, while the fire department uses a much larger hose to fight fires. Duty cycle is a capacity rating of a welding power source, expressed as a percent %.

Conversely, as output levels increase until maximum output capacity , duty cycle decreases. Applications: For connections from electrode holder and clamp to arc welder, bus, welding box or transformer. Multiple cables should be slightly spread apart. Welding Cable Class K Class K welding cable is the most commonly used. Conversely, cable that is oversized for a given amperage level does not conduct current any more effectively than properly sized cable. All of our welding wire options feature superior flexibility and durability, performing as professionally as the people who use them. Resistant to chemicals, oils, and acids and is also weather, ozone and sunlight resistant.

Designed especially where high flexibility is required such as pipelines, robotics, and tight spaces. Three Phase Power Supplies Figure 5 is an example of a chart for selecting the proper welding cable size. They stand up to temperature extremes from minus 58° F to +221° F.

Cable sizes are increased for longer lengths primarily for the purpose of minimizing cable drop. Class K cable is commonly used for stationary welding jobs. These highly flexible cables come with a rugged jacket and are available in black, green, red, blue and yellow. Heavy Duty Welding Cable for use where maximum flexibility and resistance to cuts, tears, abrasion is required. Weather, ozone and sunlight resistant jacket.

A breakdown of the insulation jacket can also be an electrical shock hazard. You can read our Cookie Policy , which describes browsing and search options available to you. Both our Class K and Class M Welding Cables are available below. Item sold in 100ft, 250ft, or 500ft Spools O. The work cable attaches to a work clamp. For higher current levels, two or more cables are often recommended and should be hooked up in parallel or together in order to share the current load.

Note that while copper is an excellent conductor of electricity, it still has a degree of resistance to the flow of electrons through it. I have seen some reference charts, but would like an explanation on how to use them. Figure 3: Example Welding Circuit Note that welding polarity does not affect the size of cable needed. As the current level increases measured in amperage or amps , the diameter of the welding cable and resulting cross sectional area of the copper stranding needs to increase. Figure 3 illustrates the welding circuit. All worn, frayed and damaged sections should be repaired immediately for proper operation and to minimize any potential safety hazards. The duty cycle rating of a welding power source is typically related to the welding processes in which it will be used, its intended use and whether it operates off of single phase or three phase power.

While the copper wire itself can handle the high temperatures generated by higher amperages before sustaining damage, the insulation protecting them would melt. In addition, worn or frayed cable connections to the work clamp, lugs or twist lock connectors can also decrease the ability to carry the current and create hot spots see examples in Figure 6. Therefore, some amount of resistance heating will occur in the cable. Rated output of the power source is simply the maximum current or amperage level in which the machine is indented to be used note that some power sources can produce higher currents than their rated output for short periods of time. Welding cables are also often rated for an ambient temperature of 30°C 86°F.

Shorter cables can carry more current than longer cables of the same diameter. Heavy Duty Welding Cable for use where maximum flexibility and resistance to cuts, tears, abrasion is required. Figure 1: Example Wire Gauge Sizes In the metric system, welding cable size is typically expressed in square millimeters mm2 , representing the cross-sectional area of the cable. Polarity and direction of current flow only affects welding characteristics and electrode selection. Figure 5: Selecting the Proper Size Welding Cable It should also be noted that in addition to proper cable size selection, it is very important to maintain the welding cable and the cable connections in good condition. To do this, you need to determine three factors.
