A product that is QPL approved is listed on the appropriate Qualified Products List. The QPL is a product specification developed by the federal government. A QPL has the names of companies who produce standard products purchased occasionally by the federal government. In order to be listed, products are examined and tested for compliance with specification requirements.
The VDE denotes conformity with the VDE standards or European or internationally harmonized standards. VDE is a West Germany Approval Agency. According to VDE, the VDE Mark “is a symbol for electrical, mechanical, thermal, toxic, radiological and other hazards.”
If a wire or cable product is UL recognized or listed, the product meets public safety requirements as designated by the Underwriters Laboratories. Each UL spec is different.
RoHS refers to the Restriction of Hazardous Substances. The European Union instituted RoHS Directive 2002/95/EC, which banned six substances from being used in the manufacturing process. RoHS requires lead, cadium, mercury, hexacalent chromium, polybrominated biphenysis, and polybrominated diphenyl ethers no longer be used in manufacturing as their use in production is dangerous to human health. A product marked RoHS compliant meets the appropriate requirements.
Wire and cable products with the HAR mark designates that they comply with the European Harmonization Standard. The HAR mark is designated by CENELEC.
CE is an abbreviation for Conformité Européenne, which is French for European Conformity. A wire or cable product with the CE Marking can be sold into the European market. The CE mark verifies that the product meets the safety regulations of the New Approach Directives of the European Union.
If a product is CSA Certified, it has received the Canadian Standards Association approval for public safety.
Yes! Welding cables are great for a variety of reasons, but safety measures should always be taken when using them. In order to protect welding cables, keep them clean of grease and oil, and out of damp conditions if they are not constructed for water. Be sure to look for imperfections in the cable and if you see any worn spots, wrap the welding cable with rubber, plastic, or friction tape. Replace the cable if damage to the welding cable is within three feet of the electrode.
Welding cable can have a neoprene jacket, making it appropriate for tight battery applications, as well as a superior battery cable alternative. Welding cables can also be used for secondary voltage resistance welding leads and in power supply applications not exceeding 600 volts.
Although welding cable is often used for battery cables in marine applications, the insulation must be oil and water-resistant. If the cable is not oil and water resistant, it can become saturated.
