Is it related to the fact that the argon arc welding machine is not good for ignition and the weldin

Let's start with the noun:

The wire connected by the ground wire clamp of the welding machine --- welding machine;

Welding torch--- argon welding gun;

Welding wire --- welding accessories that need to be filled during welding;

What you said"Wire bonding"That's what we've defined;

So,"It's not good to lighten"--- is generally referred to as low success rate of high-frequency arc initiation, referred to as low success rate of arc initiation or poor arcing;

This has nothing to do with the welding wire, if the arc is not good, even if you have an empty welding torch directly against the workpiece, it is also not good to start the arc;

Generally, there are several reasons, argon has no output, argon gas volume is small or leakage, high-frequency insulation is not good after the welding torch is aged, the polarity of the welding torch and the grounding wire is reversed (it is generally not easy to make such a mistake), the no-load voltage of the welding machine is too low (some designs are too low, or it is possible that the grid voltage you use is too low), the tungsten needle is too blunt or impure; The internal main frequency arc insulation of the welding machine is aging, the high-frequency discharge is insufficient (the high-frequency discharge electrode in the machine is accumulated by dust, or the discharge gap becomes smaller, etc.), and the high-frequency circuit in the machine is aging and damaged.

These are the reasons for the low success rate of arc initiation!

Actually, I would like to ask, is it a new machine or an old machine, or a machine under development?

The argon arc welding machine does not ignite because the electric switch is not connected properly, or there is a punch potential stuck together.

Let's do it according to the following points:

1. Whether the ground wire or the handle wire is well connected and whether the ground wire and the handle wire are intact and not falsely connected;

2. Whether the ground wire and the workpiece are falsely connected;

3. Whether the distance between the handle and the ignition on the workpiece is appropriate;

4. After turning off the gas, see if there is a squeaky sound or electric column (similar to lightning) when igniting

If you can't ignite argon arc welding, you can first look at the switch on the welding handle, and you can hear the sound of argon solenoid valve pulling after pressing, and if you don't have it, the micro switch is broken.

There is also a check of the power supply of the welding machine, if the power supply is normal, please check the fuse of the welding machine again, if it is normal, look at the indicator light and fan, if it is normal, then press the welding torch switch to see if there is high frequency, the high frequency is normal and then no ignition is the main circuit problem.

Precautions for the use of argon arc welding machine.

1. The arc welding machine should be kept away from flammable and explosive materials; The arc welding machine should be suitable for the installation environmental conditions; The arc welder should be protected from moisture and can prevent foreign objects from entering.

2. The shell of the arc welding machine should be reliably connected to the protective conductor; In order to prevent the danger caused by high voltage channeling into low pressure, a point on the secondary side of the arc welding machine should also be connected to a protective conductor.

10. Insulated shoes, gloves, work clothes, masks and other protective equipment should be worn during arc welding operations; When working in metal containers, you should also wear protective equipment such as helmets and elbow pads.

First of all, rule out whether it is the fault of the machine:

1.Check whether there is any air leakage in the skin tube of the argon arc welding gun.

2.Press the handle switch to see if it arcs.

3.Whether the argon cylinder and argon gauge valve are open.

Maintenance methods: 1Open the argon cylinder and argon gauge valve.

2.Remove the argon arc welding torch (gas-electric connector) connected to the machine, turn on the machine and press the handle switch to check if there is gas blowing out, which indicates that the welding torch is blocked or broken.

3.If it cannot be welded or gasped, check whether the argon arc welding handle switch is damaged.

4.It can be welded without gas, which may be due to the following reasons: aThe solenoid valve filter screen that controls the gas in the welding machine is blocked, and it can be removed and cleanedThe solenoid valve is damaged or the relay that controls the operation of the solenoid valve on the motherboard is damaged.

TIG welding machine safety operation procedures.

1. The use of argon arc welding machine shall be subject to the provisions of JGJ33-2001 sections, sections, and sections.

2. Check and confirm that the power supply and voltage meet the requirements, and the grounding device is safe and reliable.

3. The trachea and water pipe should be checked and confirmed to be free from external pressure and no leakage.

4. The polarity should be determined according to the performance, size and shape of the material, and then the flow rate of voltage, current and argon should be determined.

5. The argon pressure reducing valve and pipe joints installed shall not be stained with grease. After installation, tests should be carried out and unobstructed and air leaks should be confirmed.

6. The cooling water should be kept clean, and the flow rate of the cooling water should be normal during the welding process of the water-cooled welding machine, and the water should not be cut off for welding.

7. The high-frequency protection device of the high-frequency arc welding machine should be good, and it can also be protected by reducing the frequency; No short circuit shall occur, and the interlock switch in the power supply line of the oscillator shall not be tapped.

8. When using argon arc welding, the operator should wear a gas mask, and the grinding of thorium and tungsten rod should be equipped with an exhaust device, and it should be placed in a lead box during storage. The thickness of the tungsten electrode should be determined according to the welding thickness, and the power supply must be cut off when the tungsten electrode is replaced. When grinding tungsten electrodes, the operator must wear gloves and masks, and the dust from grinding should be removed in time, and thorium, cerium and tungsten electrodes should not be carried with them.

9. Other mechanical equipment with vibration should not be installed near the welding machine, and flammable and explosive materials should not be placed. The workplace should have good ventilation measures.

10. Nitrogen cylinders and argon cylinders should not be too close to the welding site, and should be placed upright and fixed, not upside down.

11. Welding operators and cooperating personnel must wear labor protection equipment according to regulations. Safety measures must be taken to prevent accidents such as electric shock, falls from heights, gas poisoning, and fire.

12. The electric welding machine used on site should be equipped with a rainproof, moisture-proof and sun-proof shed, and should be equipped with corresponding fire-fighting equipment.

1.To confirm whether the high-frequency arc striking is working, you can confirm it by listening to the sound (when the welding torch switch is operated).

2.Confirm that the torch switch is working properly, and if in doubt, you can test it with another gun. Or disconnect the aviation joint connected to the welding torch switch on the panel of the welding machine, and try the aviation joint on the same panel as the short circuit;

3.Check if there is an output of argon.

4.If all of the above are normal, and the arc does not rise, then try to touch the arc to check whether the welding power supply has output;

5.If there is no output at high frequency, then the short circuit method mentioned in point 2 cannot promote the high-frequency start, that is, the internal high-frequency arc circuit of the welding machine is damaged. Send it for repair.

Check whether the power supply and circuit are short-circuited, and if not, then see if there is a gap inside whether it is too large and whether the surface is tidy. No problem, just follow the route and keep checking. Some welding machines are set up to arc if there is no air flow through. High-frequency arc starter: If the arc is started, then check the gun belt.

Put the power button of the machine welding gun, use the multimeter DC200 gear, to measure whether the welding machine is working and whether the welding input DC55V-80V. If not, there is a problem with the main circuit. If there is a welding input, it is a minor issue.

Check the output voltage of the high-frequency board, there is a problem with the high-frequency board, and I didn't find the output power supply of the high-frequency board.

The argon arc welding machine does not ignite because the electric power supply is not connected properly, or there is a punch potential in it that sticks together. Whether the ground wire or the handle wire is well connected and whether the ground wire and the handle wire are intact and not broken. Whether the distance at which the handle is ignited on the workpiece is suitable.

After turning off the gas, see if there is a squeaky sound or electric column (similar to thunder and lightning) when the ignition is fired, or if it is not a matter of high-frequency arc triggering plate, you must try to open the air.

What is the reason why the pro-argon arc welding machine does not ignite? There can be many reasons why an TIG welder does not ignite. Here are some possible reasons:

1.Gas source problem: It may be that the argon pressure is too low or the argon pipeline is blocked, resulting in argon gas being unable to open the ignition and arc maintenance area.

2.Power supply problem: If the power supply voltage is not stable enough, the arc may not be maintained, resulting in welding failure.

3.Arc Strike Problems: If there is a problem with the arc starting, such as if the arc is too long or the arc is too far away, then the arc may go out.

4.Welding torch problems: If the welding torch is not inserted into the plug correctly, or if there is a problem inside the welding gun, then the TIG welding machine may also fail to ignite.

5.Other problems: It can also be caused by problems such as a malfunction of the welded panel, a ground fault, or a short circuit in the internal wiring.

If the TIG welder fails to ignite, every possible problem needs to be carefully examined and troubled and repaired. It is recommended to have a thorough understanding of the use and maintenance manual of the TIG welding machine during the inspection and repair process, and to follow the relevant safety operating procedures.
