ESAB creep resisting electrodes are available in VacPacTM, consisting of a recyclable plastic inner box and a strong moisture proof alumi-nium foil. The foil shows all necessary product information and is left in place after opening.

To monitor safe usage, write date and time of issuing from the stores on the foil .

ESAB VacPacTM - convenience and security.

28°C/80% RH, and still ensure a weld metal hydrogen content that’s within the lowest EN hydrogen class H5.

This is because the special LMA (Low

Moisture Absorption) coating on the electrodes effectively slows down the absorption of moisture from the air.

When properly stored under conditions where the sealed VacPac™ electrodes are not damaged, their shelf life is virtually unlimited.

The VacPac™ pack sizing options allow you to match the quantity of electrodes to your expected production rate and are available as full, half and quarter packs. Unused electrodes are re-baked or scrapped after the safe time limit has expired.

The ESAB VacPac™ vacuum packaging for MMA electrodes is ideal where control of weld metal hydrogen is essential, such as in the welding of creep resisting steels.

VacPac™ eliminates the costly storage and handling routines normally associated with the dry storage of electrodes by preventing air borne moisture absorption.

VacPac™ is simple and convenient to use ensuring that the electrodes keep their ‘factory fresh’ low moisture condition until the sealed vacuum packaging is opened. Even when the vacuum is released, the unused electrodes can remain in the opened

VacPac™ for at least 10 hours at
