                                               Features and Applications    
                                              SJ-1CM is suitable for welding of 5500Mpa high tensile steels. Applicable to wide current range and stable electric arc, it is primarily applied to the welding of high tensile structral steels. It provides solutions to the welding in the industries of bridge, architecture and pressure vessel.

                                               Points for Attention    
                                              Ensure that the purity of shielding gas and mixing ratio of properly mixed gas is well controlled.
                                              Keep the shielding gas flow at 20-25L/min
                                              Keep the electrode extension between 15-25mm
                                              Rid the welded part of rusty layer, damp, oil stain and dust, etc.
                                              Always keep torch nozzle clean and TIP in good condition.
                                              Use the wire under the best possible conditions.
