                                               Features and Applications    
                                              Suitable for all-position welding; applicable to wide current range; Stable electric arc under the operating condition of low current; few spark spatters; widely applied to structure welding like butt joint welding and fillet welding in the industries of shipbuilding, bridge, architecture and machinery.

                                               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.
