						Description and Applications | 
					
					
						| 
						 
						
						HT80S-G is a cut wire for gas tungsten arc welding (GTAW).  
						It is used for welding root pass of 600N/mm2 
						high tensile strength steels, such as pressure vessels, 
						storage tanks and penstocks.  |

						Guideline in Usage | 
					
					
						| 
						 
						
						Preheating at 50 
						∼ 
						150℃ is required when the base metal is thick and 
						restraint is high.  |
