Omega a rosin (colophony) free cored solder wire which contains no rosin/resin acids, pine oil or other naturally occurring derivatives from pine trees and has been specifically designed to help reduce the number or world wide cases of industrial asthma, related to rosin usage within a cored solder wire. Omega is available in all solder alloys, including lead free alloys and in wire gauges from 10swg (3.25mm) to 32swg (0.274mm). Omega is available in 3 formulations and varying flux percentages to suit all applications.
Omega Standard Cored Solder Wire
Omega contains no rosin (colophony), resin acids, pine oil or other naturally occurring derivatives from pine trees and has been specifically designed to reduce the number of world-wide cases of industrial asthma, related to rosin usage within a cored solder wire. Omega provides excellent wetting whilst leaving a minimal no clean, clear residue. Cleaning by batch or in-line processes is not suitable, however, if residues need to be removed use Warton Total Clean 130.
Omega II Rosin Free Cored Solder Wire
Omega II provides excellent wetting whilst leaving a minimal no clean, clear residue. Omega II is rosin free and formulated without the use of halides and is supplied as a 3%, 2% and 1% flux content wire.
Omega Plus Rosin Free Cored Solder Wire
Omega Plus+ exhibits minimal clear residues and offers an improved flow rate, with an addition of halide activation (performance in-line with the old RMA technology). Omega Plus+ is available as a 3%, 2% and 1% flux content to enable the user to determine between flow rate and acceptable residue levels.

In an independent test carried out by the Health and Safety Laboratory, the fume produced by Omega was certified as 'rosin free'. Please ask for a copy of the report.
Tests carried out on the fume produced by Omega wires showed that greater damage occurs with a rosin fume, to that of a rosin free fume.
Fume Extraction should always be used
