Cuttec can be used in the gouging, grooving and piercing of all steels and non-ferrous alloys including hard facing and stainless steels. No air or gas is required.
Electrode should be gripped in holder so that it is in line with its handle and the electrode is pointed in the direction of the intended groove and held at an angle of 5-10° relative to the work surface (a useful guide is to have the welding glove nearly touching the work piece). The arc must be struck and held momentarily and then the electrode must be moved in a slow “sawing” motion along the line to be gouged. If a deeper groove is required the above procedure should be repeated along the line of the first groove. It is advantageous to incline the work piece and gouge downhill.
To remove cracks or casting defects especially in heavy sections, repeated and overlapping grooves are made in alternate directions until the crack or defect is removed. By adopting a scooping action, defects of considerable depths can be cleared.
Piercing is particularly useful when removing bolt holes or the remains of rivets in plate up to 20mm thick. In this application the electrode must be positioned at right angles to the work piece as gouging begins.
Electrodes are packed in 4kg boxes which are then packed into 20kg shipper cartons.
Place electrodes in an oven at 250°C for half an hour.
