What is formal installation in welding equipment? What is reverse loading?
In the welding process, the two poles of the arc welding machine are respectively connected with the covered electrode and the weldment to form a complete welding circuit. For DC electric welding machine, one is extremely positive and the other is extremely negative. When the weldment is connected to the positive pole, and the electrode base (covered electrode) is connected to the negative pole, it is called the positive connection method (referred to as positive connection for short); otherwise, it is called the reverse connection method (referred to as reverse connection for short). For AC welding machine, because the polarity of the power supply is alternating, there is no problem of forward and reverse connection.

Classification and precautions of stud welding machine
Stud welding machine is a method that contacts one end of the stud welding head with the surface of the plate (or pipe fitting), energizes the arc, and applies a certain pressure to the stud welding head to complete the welding after the contact surface melts. Cylindrical head studs for arc stud welding are applicable to high-rise steel structure buildings, industrial buildings, highways, railways, bridges, iron towers, automobiles, energy sources, transportation facilities, airports, stations, power stations, pipe racks, hoisting machinery and other steel structures.
