What Is a Tig Welder and What Are Its Uses?
A Tig Welder is a vital tool for welding. It employs an electrode to create an arc between the metal and the filler material, resulting in a strong bond between the two. Tig welders are commonly used for welding metals like aluminum, stainless steel, and titanium.
Using a Tig Welder offers several benefits. Firstly, it allows for more precise welding compared to other methods. Additionally, it produces less heat, which helps prevent warping and distortion of the metal. Moreover, because Tig welders are less likely to cause sparking, they can be used safely in specific environments.
How to Use a Tig Welder (Don’t Jump the Gun!)
Step 1: Choose the Appropriate Electrode
Typically, your Tig Welder comes with a suitable electrode. However, you can replace it with tungsten alloys designed for specific materials. For most cases, using the default electrode provided by the manufacturer is sufficient. However, for advanced techniques, it’s advisable to consult a specialist or the seller.
Step 2: Prep the Tungsten Rod (Electrode)
The tungsten rod (electrode) of your machine should have a sharp or circular tip. It’s essential to rub it to some extent, especially if it’s new. Over time, the tip will naturally round due to the heat generated while welding. For AC (alternating current) welding, a rounded tip is recommended, while for DC (direct current) welding, a pointed tip is preferable. A pointed tip emits a smaller and more directed arc, whereas a rounded tip produces a broader arc.
Step 3: Configure Your Tig Welder
A standard Tig Welder provides three electricity modes: AC (Alternating Current), DCEP (Direct Current Electrode Positive), and DCEN (Direct Current Electrode Negative) for different materials. For instance, if you intend to weld aluminum, choose the AC mode. Adjust the “Cleaning/Penetrating” screen to the “Penetrating” side at around 7/10. Optionally, set the “Air on” duration to approximately 6 seconds. Finally, adjust the “Max Amps” value to around 250. These settings are common, but for specific cases, seek advice from a specialist.
Step 4: Use the Suitable Gas
Gas plays a vital role in protecting the weld from corrosion, as metals rust or oxidize rapidly at high temperatures. Pure argon is the ideal choice, but it can be expensive. Hence, it’s typically reserved for critical situations, such as welding aluminum. In less critical cases, a mixture of Argon and Carbon Dioxide can be used (e.g., for steel). Don’t forget to turn on the gas when using your Tig Welder.
Step 5: Prepare Your Workspace and Materials
To allow electricity to run through your workpiece, you may need a welding table or a large flat metal sheet. Clamp your metals onto these surfaces for stability during welding. Also, apply anti-spatter spray on the welding table (or metal sheet) to prevent liquid metal from sticking.
Step 6: Gear Up for Safety
When using a Tig Welder, it’s crucial to protect yourself with proper safety gear. Wear thick leather welding gloves, a welding protective hat (preferably a dark helmet), and closed-toe shoes. Additionally, consider wearing a welding coat or a long-sleeved shirt/jacket to prevent sparks from burning your skin.
Step 7: Let the Welding Begin!
Start by holding the electrode about one inch away from the metal. Avoid allowing them to touch, as molten metal may stick to the electrode. If this happens, turn off the machine, stop welding, remove and grind the tungsten rod, and then resume.
Stomp on the foot-pedal to initiate the flow of current and heat into the metal. Within seconds, the metal will melt, and a weld pool will form. You’ll know it’s ready when the metal becomes liquid. Start from an edge and touch the rod to ignite the weld pool.
Note: The longer the heating time, the more distorted the metal may become.
Once you’ve formed a weld pool, slightly release the pressure on the pedal to control the amount of heat and current flowing through the metal.
Tip: To ensure even welds and an even metal surface, switch to another side as welds tend to shrink as they cool down.
To create additional welds, remove the clamps and create a new weld pool by pressing the pedal again. Gradually release the pressure on the pedal to adjust the current. If the metal overheats and smells, reduce the heat. Conversely, if the metal doesn’t seem to liquefy, increase the heat.
You can repeat this process for other tasks. After completing any projects, turn off the machine and store it properly for maintenance.
5 Tips and Tricks for Tig Welding Like a Pro
If you’re a beginner welder or want to enhance your skills, here are some tips and tricks to help you TIG weld like a pro:
1. Don’t Fear Experimentation
TIG welding is all about finding the right balance of heat, current, and gas flow. Experiment with different settings until you discover what works best for you.
