The most straightforward is to use file repair.... If the conditions permit, you can also buy an electrode grinder, but it is not cheap, that is.Spot welding machine instructions, to see your spot what kind of models, a general resistance welder, energy storage welder midbandspor welder, welding, from the way and butt welding, seam welding, spot welding, projection welding, which is what you want? The control part of each model is different, the parameter adjustment is different, and the natural instruction will be different.s
Belonging to a welding machine in resistance welding, resistance welding is divided into four forms: welding spot welding, projection welding, butt welding, seam welding. As a result of wide range of applications, the form of direct, so we are accustomed to welding machine collectively. So you ask the spot welding control principle, in fact, is the principle of resistance welding.Resistance welding is a method of welding the workpiece by applying pressure through the electrode and using the resistance heat produced by the current passing through the contact surface of the joint and the adjacent region.The physical essence of resistance welding process, is to use a lot of energy of plastic deformation and resistance to heat and the welding zone itself, so close to the lattice distance form the metal bond between the metal atom two separation performance, to produce a sufficient amount of grain in the combined surface and get the weld joint of solder joints, or. Resistance welding is a welding quality stability, high production efficiency, easy to realize mechanization, automation of the connection method, widely used in automobile, aerospace, electronics, household appliances and other fields.s
Dissimilar metal welding, one should take into account their melting point, and the two is to pay attention to spot welding machine selection and power size. Three, pay attention to welding electrode material, four is to adjust welding parameters, try several specifications. If you need help, contact a professional spot welder manufacturer.s
You this is the equivalent of a counter current through the method, considered a record, but the conventional signal acquisition counter voltage value, you can pass the current into voltage does not exceed the value of 30V to counter acquisition equipment above, when the voltage reaches above 5V can be considered to be a high level, a number of the best. You calculate this current size range, across an appropriate resistance, by recording more than 5V times more than by the voltage of this resistance to count.s
