Esab Vac Pac 7018 4 Pound Package

ESAB 7018-1 Prime is a reliable, high-quality electrode, providing high deposition rate and extra low moisture absorption. It provides excellent welding pool control, minimal spatter level, good arc strike and easy slag removal making it easy to weld with, including in out-of-position welding. Particularly suitable for welding high strength low-alloy steels. The low-temperature impact strength of the weld metal should be noted.

The prevention of hydrogen induced cracking in thick structural steels or porosity in stainless or nickel-base weld metal, by controlling the moisture re-absorption in the coating of low hydrogen electrodes, can be very costly. In demanding applications, such as offshore fabrication, the cost of climate controlled storage and handling and the associated administrations are often calculated to exceed the cost of the consumables itself. With ESAB 7018-1 Prime VacPac vacuum packaging, these costs are completely avoided.

No Re-Baking, No Holding Ovens, No Quivers

ESAB 7018-1 Prime electrodes can be used straight from the package without the need to re-bake them and store them temporarily in holding ovens and quivers. The laminated, multi-layer aluminum foil is vacuum-sealed around a strong plastic inner box and effectively protects the electrodes against moisture re-absorbtion from the air. Protected by a cardboard outer box, they have unlimited shelf life and do not require special warehouse conditions, provided they are handled with care and the foil is not damaged. VacPac also helps eliminate damage during shipping compared to metal cans, which can get dented in transit, compromising the quality of the electrodes. Upon opening, fresh and dry electrodes are guaranteed when the vacuum is confirmed.

Safe Welding After Opening

ESAB 7018-1 Prime welding electrodes are low moisture absorption (LMA) with a coating that only slowly re-absorbs moisture from the air**. The safe exposure time is 12 hours* after opening the VacPac with the foil left in place. For optimal security, it is recommended to take out only one electrode at a time. ESAB’s VacPac packaging provides security and makes the welder’s life easier; in offshore and pressure vessel fabrication, the petrochemical industry, the food processing industry and other applications where the prevention of cold cracking or porosity is crucial.
