Q: Our welding machine and grounding wire did not bother it at all.? It's still the same, but the welder is a little bit out of arc Partial arc? What's the matter?: Compared with the human body, the earth resistance is small, when the equipment (electrical equipment) leakage lead to the shell charged, the current flows directly into the small resistance of the earth, to avoid electric shock. Therefore, the grounding of the electrical appliance is required

Q: What's the difference between argon arc welding machine 380V with two wire input and three wire input?: Two arc welding argon arc welding machine is single-phase 380V.The argon arc welding machine with three wire inputs is three-phase 380V.Three phase argon arc welding machine has good stability. Now the inverter arc welding is the power input mode.Because of the unbalanced voltage of the network, the welding parameters of single-phase arc welding is poor. Mainly old-fashioned frequency AC arc welding machine based. Backward technology.

Q: High frequency is normal (between two points of spark is not small), arc can also be wiped, the current is not small (adjustable). It is difficult to start the arc.: That is, there is something wrong with your needle. Some of the machines are just the beginning of the time. The current is unstable and the current is steady

Q: I have a 380V three-phase DC argon arc welding machine, can not be changed to 220V single-phase DC argon arc welding machine? Thanks for your help!: 380V three-phase argon arc welding machine can not be changed into 220V single-phase, because the 220V voltage can not drive three-phase argon arc welding, so the welder will not work at all.Argon arc welding is a kind of welding technology using argon gas as protective gas. Also called argon gas shielded welding. That is, argon shielded gas is applied around the arc welding, and the air is separated from the welding zone to prevent the oxidation of the welding zone. Argon arc welding technology is based on the principle of arc welding on using argon protection for metal welding, the welding material in high current to be welded on the substrate is melted into liquid form of molten pool, the metal to be welded and welding material to a welding technology of metallurgical bonding.

Q: Argon arc welding machine starting indicator light is not bright, fan turn is how, can not welding: Check the circuit

Q: Welding aluminum parts by argon arc welding, I made a control cabinet, servo motor to drive the welding torch to move, and control welding current, control welding stop,There are 2 servo motors in the cabinet,.1 PLC. When I arc, the high frequency of the welding machine will affect my welding machine, and the servo motor will run around,PLC the first second inputs X1.X2 will flash. When the control panel is out of power, the welder will start arcing, and the alarm light on my Cabinet will flash (no power is on)The alarm beeps, too. Put awayA filter in front of my PLC with the servo driver, but the driver in front of hell no isolation transformer, alarm lamp in front of no isolation transformer, servo driver CN1 input port with no shielding line: In the encoder line with magnetic ring, PLC servo CN1 input screen mesh shield, and mesh shielded wire welded to the CN1 plug metal shell

Q: I have a household type 200 inverter manual welding machine. I want to weld stainless steel. Can you change it into argon arc welding machine?: I am a professional engaged in welding machine R & D. Tell you exactly: no!

Q: Can argon arc welding machine be used as DC welding machine?: That depends on what machine, general DC arc welding is negative, when the welding torch use, positive when the ground wire. You can use it in the opposite direction, but it doesn't work well.

Q: WSM-200A inverter DC pulse argon arc welding machine access voltage, what parts of the assembly damage?: The machine is installed AC input overvoltage protection power source has certain help application (a degaussing resistor and a MYL132D431 varistor) if the short time access "voltage is too large and equipped with about 10A insurance, power supply, welding machine will not damage what, just on the knife fuse will be burned, thus protecting welder but, the fuse is too large, the access time is long, will damage the filter capacitor and even if the bridge, high voltage filter capacitor is not damaged if it might blow pipe field.

Q: Can argon arc welding machine be used as cutting machine?: It should be possible to change the gas to compressed air and adjust the current to the extent that it can be burned through the material. These have to be tested for long experience. In addition, argon saves some of the possible tungsten charges, and uses argon and tungsten to save some. You can change the electrode during the test to see if the effect is better.
