Other Specification:

PHIL MARKET ONLY

FOR PHILIPPINE MARKET ONLY

I. APPLICATIONS:

Welding of all types of mild (low carbon) steel such as:

  • Steel structure-trusses, portal frames, tubed framework

  • Sheet and plate metal structures and containers-plating, storage tanks, hoppers, silos, bins

  • General Steel fabrication & assembly job

  • Welding of jeep, auto bodies & vehicles

  • Welding of farm and agriculture equipments, fences, farm tools, etc.

  • Light steel frames - grills, ornamental and gate works, furniture

  • General workshop welding and maintenance

  • Compatible and suitable for welding steels to:

            ASTM (eg. A36)

            BS EN 10025 (eg. S275, S275 JR)

            BS 4360 (eg. Grade 40, 43)

            API Std. 5L (eg. Grade A, B, A25, X42, X46)

           JIS   G3106 (eg. SS41, SM41)

II. DESCRIPTIONS:

N-55 is the most popular welder-friendly general purpose rutile coated welding electrode which has the following special features.

  • Very easy initial arc strike (ignition and “cold” re-striking properties, for easy tac welding or point by point welding

  • Ultra smooth, quiet and stable arc

  • Low level and odorless fume

  • Easy slag removal-almost self-releasing in most conditions

  • Beautiful and finely rippled bead even in fillet welding for nice finishing

  • Outstanding all position welding performance including vertical down

  • Can use “touch type” or “contact” welding giving ease and comfort to welders

  • Fine and very few spattering

  • Suitable for both AC & DC +/- welding source (even on low open circuit voltage - 50V)

III. NOTES ON USAGE:

  • In the case of vertical downward welding, manipulate the electrode keeping its tip in contact with mother plate.

  • Pay attention not to exceed the range of proper currents. Welding with excessive current not only lowers X-ray soundness, but also causes increase of spatter, undercut and insufficient slag covering.

  • Dry the electrodes at 70-100°C for 30-60 minutes before use. Excessive moisture absorption lowers usability and may result in some porosities.
