Tigama Premium Copper Coated SG3 MIG Wire 16Kg
Tigama SG3 precision layer wound copper coated wire meets the EN 440 G4Si, AWS A 5.18 ER70S-6 and CE EN 13479 classifications.
This premium quality SG3 wire offers superb welding parameters on all carbon steels allowing for smoother spatter free welding.
SG3 has higher Silicon and Manganese content making it both higher strength and better able to cope with rusty steel plate without producing porous welds.
Because of the higher silicon it flows better and for this reason many welders prefer it over SG2.
SG3 also carries current better and will produce welds of acceptable appearance on settings at least 100 amps higher than SG2, with advantageous effect on productivity.
Supplied on 16kg, K300 type steel baskets an alternative to plastic reels for easy recycling.
