STAR GOUGING
Exothermic electrode, specially designed for cutting, gouging and piercing operations on all metals without the use of air or oxygen. Easy to use with little skill required. Operates at lower current and produces fewer fumes than would normally be expected from an electrode of this type. Metal surfaces are seared by the force of the arc leaving them clean and ready for subsequent welding operations. Smooth and even grooves are easily produced.
Applications include, grooving, cutting, gouging and piercing operations on all metals, including those which would normally present difficulties by machining. These include hard enable steels, armour plate, hard weld overlays, cast iron and stainless steels. The electrodes are ideal for back gouging of butt-welded seams and almost indispensable for the preparation of cast irons prior to welding repair.

STAR ACA GOUGING
Star Air Carbon Arc (ACA) Gouging electrodes are used for gouging, cutting, bevel and piercing of all electrically conductive materials. In this process, the arc is used to melt the metal and the molten metal is then blown away by a jet of compressed air. Typical applications are removal of old welds and opening of cracks before re-welding.
On-board heavy lift vessels
Removal of welds on sections which have been welded to the deck for securing deck cargo during voyage. The flat gouging electrode (15 x 5 x 305mm) is used to scarfing down old welds to the level of the deck.
