Tig Welder

In TIG welding, the primary gas used is pure argon. This inert gas acts as a shield around the arc, protecting the weld pool from contamination by the surrounding air. Contamination, particularly from oxygen, weakens the weld.

Here's a breakdown of why pure argon is the go-to choice:

• Versatility: Pure argon works well for welding various metals like mild steel, stainless steel, and aluminum.
• Cleanliness: It promotes clean welds with minimal post-weld cleaning.
• Stable Arc: Argon helps maintain a stable arc for optimal weld penetration.

Important Note: While pure argon is excellent for most TIG welding applications, some advanced techniques might involve using other gases or gas mixtures. It's always best to consult your machine's manual or a professional welder for specific recommendations based on your project and materials

What is the Purpose of Pulse TIG Welding?

TIG welding is known for its precision and control, but sometimes achieving deep welds can be tricky. Especially with thin materials like sheet metal or heat-sensitive metals like stainless steel, too much heat can lead to warping or burn-through.

This is where pulse TIG welding comes in. It's an advanced technique that allows you to achieve deeper welds with less overall heat input. Here's how it works:

Imagine tapping the gas pedal in your car instead of holding it down constantly. Pulse TIG works similarly, alternating between a higher "peak" current for a short pulse and a lower "background" current. This delivers heat in short bursts, allowing it to penetrate deeply into the weld zone while minimizing the overall heat input to the surrounding metal.

The benefits of pulse TIG welding include:

• Reduced risk of warping or burn-through: Ideal for thin sheet metal and heat-sensitive materials.
• Deeper weld penetration: Achieve strong welds without excessive heat.
• Improved weld quality: Minimizes splatter and creates a cleaner weld pool.

However, pulse TIG welding is an advanced technique with a steeper learning curve. Here are some additional things to consider:

• Not essential for beginners: Mastering basic TIG welding is a more practical first step for most welders.
• Requires practice and experience: Setting the three key parameters (pulse width, pulse percentage, and pulse frequency) takes practice to achieve optimal results.

Overall, pulse TIG welding is a valuable technique for specific applications. If you're working with thin materials or heat-sensitive metals and need to achieve deep welds, it's worth learning. However, for beginners and many experienced welders, mastering basic TIG welding is a more practical first step.
