WA2 for Weld Current MonitoringWA2

For the accurate measurement of weld current, ENTRON offers its second generation weld analyzer, the ENTRON WA2. The rechargeable WA2 gives welding engineers, technicians and operators a convenient tool to measure weld system current for monitoring system conditions, improving process quality and troubleshooting weld schedules to analyze, fault-find and improve process quality on today’s sophisticated welding control systems. Full traceability gives you the confidence in your processes that your customers demand.

DLC Weld Force GaugeDLC Gauge

For the accurate measurement of weld force, Tuffaloy offers its newest gauge – the DLC. This affordable, high accuracy gauge with large LCD display, offers field selectable units in pounds (lb), kilograms (kg), newtons (N) and kilonewtons (kN). High Strength, spring mounted load cell features 150% overload capacity, a large landing pad for electrode pinch point and requires electrode gap of only 9/16”. Full 5 Digit large LCD Display is environmentally sealed for rugged applications and comes standard with Peak Hold Feature.

The process of resistance welding makes it possible to join most metals, similar or dissimilar. Bonds of adequate strength are obtainable for an extremely wide range of applications. Selecting electrodes of the proper alloy is a most important consideration in producing good welds at the required speed. The chart below is a valuable guide to this selection.

The weldability of two materials as expressed in the following chart has been derived after careful laboratory study and field survey of many factors which influence the welding or resultant weld of the metals. The factors include:

  1. Thermal and electrical conductivity
  2. Metallurgical properties
  3. Nature of resultant weld or alloy
  4. Weld strength
  5. Relative accuracy in control of welding conditions necessary

The weldability of metals as shown in the chart applies only when conventional spot welding methods are used on similar thicknesses of material. However, many metal combinations which are listed as having a “poor weldability” may be satisfactorily joined by using a special setup or procedure.

There is a specific Alloy for each specific welding application. Our experienced engineers will provide assistance with special problems. Contact us today!

The Weld Analyzer offers the engineering professional the facilities to analyze, fault-find and improve process quality on today's sophisticated welding control systems.

California’s Safe Drinking Water and Toxic Enforcement Act of 1986, otherwise known as Proposition 65 (“Prop. 65”), requires that all companies selling or distributing consumer products into California inform consumers if those products could cause exposure to chemicals listed by the state of California as carcinogens or reproductive toxicants. While Prop. 65 has been in effect for decades, recent regulatory changes have resulted in a broader application of the statute’s warning requirements.

Tuffaloy does not believe that, when used as intended, our products will result in an exposure to a listed-substance above the safe harbor levels established by the State of California. However, recognizing that our products may be used in variety of ways and in an abundance of caution, Tuffaloy will begin placing a short-form Prop. 65 warning on the labels of products that contain listed Prop. 65 substances. Tuffaloy is providing these warning based on the knowledge of the presence of one or more listed chemicals without evaluating the level of exposure, as not all listed chemicals have an established exposure limit. A Prop. 65 warning does not mean that a product is in violation of any product safety standards or requirements—the State of California has explained that these mandated warnings are “not the same as a regulatory decision that product is ‘safe’ or ‘unsafe.’”

The alloyed copper, brass, steel, stainless-steel and nickel coatings that Tuffaloy uses to manufacture our products may contain lead, beryllium, nickel, cobalt and other elements listed under Prop. 65. The alloys we use in our manufacturing process are not themselves listed pursuant to Prop. 65; however, individual chemicals alloyed into and fully encapsulated in the metals are listed. Although these substances may only be present in trace amounts, the presence of these materials can trigger Prop. 65’s warning requirements and even substantial penalties for failure to comply. The warning below will appear on all Tuffaloy and CMW packaging labels for products that contain listed Prop. 65 substances. In addition to on-product warnings, our webpages will also carry the same warnings so that consumers in California can see the warnings prior to purchase.
