Remark:  1.   For the protection of the CO2 gas, purity should be in the 99.8% above, flow 20 to 25 l/minutes.

                  2.  Multichannel welding, layer temperature between  150-200 °C.

                  3.  The water, rust, oil pollution and impurit in  parent metal should be cleared away before welding.

                  4.  Wire in should be used as quickly as possible after opening, has not used up wire not long naked in the air.

                  5.  Because the wire is soft,  wire feed wheel  locking shall not be too tight.
