Is the spot welding machine good or DC?
- AC welding machine is the wire package step-down transformer using welding rod, this machine, old technology, power consumption, copper consumption.The DC welding machine includes thyristor, inverter (MOS tube, IGBT single tube and IGBT module), and the technology is more and more advanced.The inverter is a new technology that has appeared in the last 10 years, saving more than 35%. Because there is no large transformer, a great deal of copper is saved, and the transformer consumption is also reduced a lot. The disadvantage of DC is that the magnetic deviation blows, and the other is all advantages. Arc stability, weld formation is good, and there is welding rod, general acid welding rod is AC and DC can use, alkaline welding rod recommend DC, cellulose electrode, seems to only dc.s
380V 150KVA flash butt welder, what kind of cable do you need?
- The wire diameter is usually calculated according to the following formula:Copper wire: S= IL / 54.4UAluminum wire: S= IL / 34UIn style:I - the maximum current (A) passed through a wireL - the length of the wire (M)U - permissible power drop (V)S - cross sectional area of the conductor (MM2)So, you know what material and how long wires can be used to determine how much cable you want.s
Two can welding be changed into a pair of welding machines?
- Two welding machine can not be changed to welding machines
What kind of power supply is common for welding machines used on site?
- 1. If you already have a welder, you can calculate the data according to the welding machine nameplate data. The power supply of the welder is usually single-phase 380V, multiplied by the nameplate, and the I1max is the maximum power of the welder;2. If you do not have a welder, please refer to the answer on the first floor.s
To the welder 380 V, 36 volt transformer always burn, what's the matter?
- The butt welding machine is intermittently working and won't burn easily. If burned frequently, it means that the no-load current is too large and it is very hot when not working. The countermeasures are: after burn wound, asked the chef to the primary coil (a primary coil) increase the number of turns of 5%, this will not be burned, but the general master are not willing to give you more laps, though you give more money. They will say "the place is not enough." "not open around ah" and so on the grounds, because more laps rarely burned, so messed up their jobs, cut its way. Not just the transformer, the maintenance of the motor is the case. There is a way to let him to ensure the use of time, such as a month burned once, you let him that two years is not burned, is winding double the fee increase, the general master will agree, control the time they have burned, grasp than you.s
What is the reason that the welding band saw blade is not firmly used after two years of flash butt welding machine? How to solve?
- It is suggested that the new jaw be replaced and the two maintenance of transformer shall be carried out. Our company will do the maintenance and maintenance of old machines for the major steel wire rope and steel cord industry all year rounds
