Understanding Arc Welders
An arc welder is a type of welding machine that uses an electric arc to create a weld. It is commonly used in industrial and construction settings for joining metals together. Understanding how arc welders work is essential if you want to convert one into a TIG (Tungsten Inert Gas) welder.
Basic Principles
At its core, an arc welder consists of a power source, an electrode holder or torch, and a ground clamp. The power source generates a high current, which flows through the electrode holder and creates an electrical arc between the electrode (also known as the welding rod) and the workpiece. The heat generated by the arc melts the base metal and the electrode, creating a molten pool that fuses the two together when it cools.
The arc welder’s power source can be either AC (alternating current) or DC (direct current). AC machines are typically used for welding materials like aluminum, while DC machines are more versatile and can handle a wider range of materials, including steel and stainless steel.
Components of an Arc Welder
Aside from the power source, an arc welder also consists of several other components, including:
| 1. | Transformer | – Converts the input voltage to the desired welding voltage and amperage. |
| 2. | Rectifier | – Converts AC current into DC current. |
| 3. | Control panel | – Allows the operator to adjust the welding current and other settings. |
| 4. | Cables and connectors | – Carry the electrical current from the power source to the welding torch and ground clamp. |
Additionally, some arc welders may have built-in safety features like thermal overload protection and voltage regulation to ensure safe and reliable operation.
Understanding these basic principles and components of an arc welder is the foundation for converting it into a TIG welder. By modifying or adding certain components, such as a TIG torch and a shielding gas system, you can transform your arc welder into a versatile TIG welding machine.
TIG Welding Explained
TIG (Tungsten Inert Gas) welding is a precise and versatile welding process that uses a non-consumable tungsten electrode to create an arc that melts the base metal and forms a weld. It is commonly used for welding materials such as stainless steel, aluminum, and copper.
The TIG welding process involves using both hands – one to hold the welding torch and the other to feed the filler rod into the weld pool. Unlike other welding processes, TIG welding requires a higher level of skill and control due to its precise nature.
The TIG Welding Setup
Before starting TIG welding, it is important to set up the welding machine properly. This involves connecting the gas supply (typically argon) to the machine and adjusting the gas flow rate. The electrode, usually made of tungsten, also needs to be properly prepared and inserted into the torch.

Next, the workpiece needs to be properly cleaned and prepared. This involves removing any dirt, oil, or rust that may interfere with the welding process. Additionally, the workpiece may need to be grounded to prevent electrical shock.
The TIG Welding Technique
Once the setup is complete, the TIG welding technique can be employed. This involves holding the torch at a specific angle and maintaining a consistent distance between the tungsten electrode and the workpiece. The filler rod is fed into the weld pool at a controlled rate to add material and create the desired weld shape.
TIG welding allows for precise control over the welding process, making it suitable for welding thin materials, intricate joints, and critical applications where strength and aesthetics are important. It produces high-quality welds with minimal spatter and distortion.
Advantages of TIG Welding
TIG welding offers several advantages over other welding processes. It provides excellent control, allowing for precise welds and intricate designs. It also produces high-quality welds with minimal cleanup required. TIG welding is versatile, capable of welding a wide range of materials, including non-ferrous metals. Additionally, it does not produce smoke or fumes, making it a cleaner process.
In conclusion, TIG welding is a versatile and precise welding process that requires skill and control. With the right setup and technique, it can produce high-quality welds on various materials. Whether you are a hobbyist or a professional welder, TIG welding is a valuable skill to have.
Conversion Process
Converting an arc welder to TIG requires several steps and modifications. Here is a step-by-step guide to help you through the conversion process:
- Inspect your arc welder: Before starting the conversion process, make sure to thoroughly inspect your arc welder for any signs of damage or wear. It’s important to have a functioning and reliable arc welder as the base for the conversion.
- Gather necessary materials: To convert your arc welder to TIG, you will need specific materials including a TIG torch, shielding gas supply, foot pedal, and welding wire.
- Disconnect power supply: Before making any modifications, ensure that your arc welder is completely disconnected from any power source to prevent any electrical accidents.
- Remove the electrode holder: Since TIG welding does not require an electrode holder, you will need to remove it from your arc welder. This will make space for the TIG torch.
- Install the TIG torch: Mount the TIG torch onto the arc welder, making sure it is securely attached. This will serve as the new welding torch for TIG welding.
- Connect the shielding gas supply: Attach the shielding gas supply to your arc welder, ensuring a proper seal. This will provide the necessary gas shield during TIG welding.
- Install the foot pedal: The foot pedal allows you to control the amperage of the TIG welding process. Connect the foot pedal to your arc welder according to the manufacturer’s instructions.
- Configure the settings: Adjust the settings on your arc welder to accommodate TIG welding. This may include changing the voltage and current settings to match the requirements of TIG welding.
- Test the TIG welding setup: Before using your newly converted welder, it’s important to perform a test weld to ensure everything is functioning properly. Set up a test piece and practice TIG welding to ensure the quality of your welds.
Remember, converting an arc welder to TIG requires technical knowledge and skills. If you are unsure or uncomfortable with the process, it’s recommended to seek assistance from a professional or take a welding course to learn the necessary skills.
