Descriptions
Low Hydrogen basic coated AC/DC electrode. The weld metal deposit is of a high metallurgical and radiographic standard complying to AWS A5.1 grade 1

Characteristics
ISOARC 133 is specifically formulated to control heat input and reduce distortion. It is easy to use in all welding positions, has a stable arc and easily controlled slag. Suitable for AC and DC. The product is also available in a vacuum sealed packaging on request.

Applications
ISOARC 133 is widely used in the construction and fabrication industry on beams, angles, channel iron, pipelines, pressure tanks, railways carriages, ship building and by maintenance repair specialists.

Procedures
Use ISOARC 133 with normal low-hydrogen techniques. As short an arc is to be kept were possible at all times. When starting a new electrode the arc should be initiated a short distance ahead of the start or crater and worked back over this distance before continuing the weld in the required direction. Avoid weaving and use several stringer beads.

Redrying
Low hydrogen Electrodes must be re-baked prior to use The electrodes should be heated to 350°C - 370C for 1-2 hours prior to use.
