MIG/MAG cored wires range for C-Mn and low-alloy steels.

FLUXOFIL 20HD is a seamless copper coated rutile flux cored wire for gas-shielded metal arc welding of fine grain steels with operating temperatures from -40°C up to +450°C.
It meets the classifications:
   EN ISO 17632-A: T 46 4 1Ni P M 1 H5       -        AWS A5.29: E81T1-Ni1M-JH4
   EN ISO 17632-B: T554T1-1MA-N1-UH5    -     AWS A5.36: E81T12-M21A2-Ni1-H4

Product Advantages

✔ Can be used in all positions including vertically up and vertically down.


The enhanced degree of fill, results in a higher current carrying capacity and deposition rate. It can be welded in all positions using only one parameter setting (24 volts, wire feed 9 m/min, wire dia. 1,2 mm). The weld metal produced features excellent mechanical-technological properties and a hydrogen content of hydrogen < 5 ml per 100g deposited weld metal. Low spatter loss, easy slag removal producing finely rippled, pore-free welds without undercut. To be used under mixed gas.

Available in B300, S200.
Diameter from 1,2 to 1,6 mm.
