DN2 Series Portable Precision Spot Welding Machine    DN2 series portable precision spot welding machine is a new welding equipment controlled by controllable silicon. The welding machine is equipped with adjustable device which showing us the heat quantity and the welding time. It is widely used in spot welding of thin-slab material for filing cabinets and switch cabinets. With a flexible wire of three meters between the welding electrode and the mainframe, the welding can be done at any place. This kind of welding machine has such properties as excellent welding-spots, simple and flexible operation.         　 Model Powder Voltage (V) Power Phase Regulation Grade Continuous Loading Rate (%) Specified Capacity(kVA) Welding Thickness (mm) DN2-25 380 1 Continuous, non grade 20 25 0.1+0.1~1+1 DN2-40 380 1 Continuous, non grade 20 40 0.1+0.1~1.5+1.5 DN2-75 380 1 Continuous, non grade 20 75 0.1+0.1~2+2
