						Description and Applications | 
					
					
						
						HR70S-G is a gas 
						metal arc welding wire with CO2 shielding. Arc is 
						stable, spatters are few, and weld ability is excellent, 
						even in high welding current range. High efficiency is 
						obtained since deposition rate is high and penetration 
						is deep. 
						Butt or fillet MAG welding of mild steel an 500N/mm2 
						high tensile strength steel such as ships, vehicles, 
						buildings, bridges, and industrial machinery. |

								| 
								1. | 
								
								Suitable for flat, horizontal, angle welding at 
								a high current range. | 
							 
							
								| 
								2. | 
								
								Automatic 
								flat and vertical downward is possible. | 
							 
							
								| 
								3. | 
								
								
								Use CO2 
								gas for shielding in welding. |
