AUSTARC 16TC SUMMARY Basic/Twin Coated (TC) Manual Arc Electrode Versatile/All Positional (Especially Vertical Up) Capabilities Reliable, Low Temperature Impact Toughness Easy to Strike and Re-Strike Smooth Performance on Low OCV AC Welding Machines IDENTIFICATION PACKAGING DATA Coating - Light Grey Tip - Bronze Imprint - WIA 4916A CLASSIFICATION - AS/NZS 4855-B - E49 16-A U H10 AWS A5.1: E7016 H8 DESCRIPTION AND APPLICATION Smooth running, basic low hydrogen electrode, developed for all positional (except vertical down) welding, using AC or DC power sources. It has exceptional arc stability and weldability and delivers high quality weld deposits with reliable notch toughness to - 40 ̊C. Austarc 16TC is manufactured using a unique twin coating extrusion process, which means all the arc stabilising elements are concentrated in the inner coating. This delivers significantly improved arc stability and control for all applications. OPERATIONAL DATA ELECTRODE SIZE (MM) ELECTRODE LENGTH (MM) WELDING CURRENT RANGE *(A) 2.5 300 60 - 90 3.2 380 90 - 135 4.0 380 140 - 190 5.0 450 190 - 240 6.0 450 250 - 310 *Please note, 2.5 and 3.2 Austarc 16TC are recommended for DC+ or AC (minimum 45 OCV) operation, whereas 4.0, 5.0 and 6.0mm sizes require a minimum of 55 OCV for stable AC operation.
