Luvata MIG Welding Contact Tips and Tubes

Contact Tips

For many years, deoxidized phosphorus copper (DHP) was the preferred alloy for contact tips because of its low cost and availability – it is still in widespread use today. However, for more demanding applications requiring high wear characteristics and resistance to softening, other alloys can give a superior performance and are better suited for the most rigorous arc welding conditions.

Dispersion strengthened copper (DSC) tips are unsurpassed in quality and reliability. DSC tips will maintain their hardness at the highest temperatures and are extremely durable.

MIG-contact tips are available in a choice of alloys:

  • Dispersion Strengthened Copper (DSC)
  • Copper Chrome Zirconium (CuCrZr)
  • Silver Bearing Copper (CuAg)
  • Deoxidized Phosphorus Copper (DHP)

Each material has its advantages and disadvantages, but superior performance with little or no additional cost has been proven multiple times.

This same material can be applied to:

  • MIG-welding contact tips
  • MIG-welding contact tubes
  • Sub arc welding tips
  • Projection welding electrodes
  • Stud welding collets
  • Flame spray nozzles
  • Gas cutting nozzles

Tubes for Contact Tips

As part of the welding range of products, Luvata produces tubes for contact tips. We use a manufacturing process whereby the final drawing operation is through a die and mandrel. Since the mandrel determines the size and shape of the bore, the process guarantees an exceptionally tight diameter and a smooth surface finish for the bore.

Since the bore does not need to be calibrated, this leads to a cost saving for the tip manufacturer, as well as fewer interruptions for the welder when in operation.
