Low hydrogen type with unusual ability to absorb impurities. Non-machinable on cast iron.
ISOARC 270 can be used as a sealer layer on dirty cast iron, for hard facing of cast iron and on difficult welds where pure nickel or nickel-iron electrodes don’t fuse. To seal impurities, use as a sealer run. If machinable deposits are required, ISOARC 210 can be applied onto ISOARC 270.
On cast iron use a long arc with quick movements. Otherwise, use normal low hydrogen procedure.
