Every welder knows that the hydrogen content is a decisive factor for a safe and reliable welding seam. This is the reason why we not only produce stick electrodes with a low hydrogen content, we also take care that the coating does not absorbe any moisture and offer our DRY SYSTEM premium packaging which ensures safe welding with low-hydrogen weld metal up to nine hours after opening.
The Best for the Best: H4 R stick electrodes
24th Feb 2020
H4 R is a certain classification from the American Welding Association AWS:
- The H4 means that the hydrogen level in the all weld metals is below 4 ml per 100 g weld metal. This hydrogen level will avoid hydrogen induced cracks.
- The R means that the coating is moisture resistant, which means that the coating is not hygroscopic.
We offer a broad range of stick electrodes with this classification. Find below our most popular ones:

Packaging
To ensure safe welding with low-hydrogen weld metal we recommend our premium packaging DRY SYSTEM.
![]() | DRY SYSTEM is the best solution for welding on site of high strength constructional steels. Hermetically sealed vaccuum pack, lower weight per packaging and thanks to our H4 R moisture resistant coating welders can use it up to 9 hours without the necessity of re-drying. |
Beside DRY SYSTEM we offer another advanced packaging solution. Our metal tins are very popular among pipeline welders. They offer a strong protection against dirt and bad weather conditions on site and are re-lockable with a plastic lid.
