FLUX CORED OPEN ARC WIRE

AI-1500-TDSAWS/ASME A5.20.79: E71-T11
AS/NZS 2203.1-1990: ETP-GNn-W500A.CM1H10
AI-1500 is a self-shielded welding wire for general purpose welding in all positions. Used on DC electrode negative, the wire has a smooth spray transfer even at low currents and arc voltages.
Unlike gas-shielded wires where a short wire stick out of 10-15 mm is preferred, the self-shielded wires require a longer stick out of 25-50 mm. This is so that the heating effect on the wire will cause the gas shielding materials to decompose and provide the shield. Too short a stick out does not allow the shield to form and porosity can result.
AI-1500 is designed to operate in spray transfer mode at lower amps and voltages than is usual for a particular wire diameter. The low heat input makes it particularly suited for fabrication of thin gauge materials.
Applications: All position single and multi-pass welding of mild and low alloy steel where impact properties are not required. Particularly suited for high speed welding of thin gauge material. General purpose welding in all positions where operators appeal is main consideration.

Depositing a weld that is low in sulphur and this then in turn offers increased resistance to hot cracking. It is designed to be used with a long stick out and the flux cored capability makes it ideal to use onsite applications.
Applications include: Build-up of large castings, large fillet welding. Good operator appeal.
