What Does The Foot Pedal Do On A TIG Welder?

Want to know the exact purpose the foot pedal on a TIG welder serves?

The basic function of a foot pedal is to provide you control of the welding current (amperage) and sometimes shield gas flow during the welding process. The foot pedal enables you to use both hands to focus on the welding task.

So, with precise control of the foot pedal, you will be able to control the amperage without using your hands.

This will help you retain focus while working on complex projects and delicate materials.

Once you master the control of the foot pedal, you will be able to increase productivity.

Although TIG welding is a slow process, with perfect control of the foot pedal, you can increase your productivity significantly.

Some foot pedals also provide you control of the shielding gas, which further enhances the welding process and increases productivity.

Let’s dive into the details of the foot pedal in a TIG Welder.

Understanding Foot Pedal’s Functionality

A foot pedal services two functions, but most of them are used for just the first one.

1. Welding Current or Amperage Control

The primary function of a foot pedal in a TIG welder is to control the amperage. When you press down the pedal, it will increase the amperage and in turn generate more heat which will increase the temperature of the weld pool.

On the other hand, when you release the pressure from the pedal it will decrease the current and cool the weld pool.

This precise control of the amperage allows the welders to quickly adapt to the changing thickness and welding positions without any downtime during work.

2. Shielding Gas Control

Some foot pedals also have built-in functionality that allows you to control the shielding gas flow. The shielding gas protects the weld pool from contamination and you may need to increase or decrease it during welding.

With precise control of the gas from the foot pedal, your hands will be left free to focus on the task and there will be no downtime.

3. Responsiveness and Sensitivity of a Foot Pedal

The effectiveness of a foot pedal depends on its responsiveness and sensitivity. Good quality foot pedals come with high responsiveness and sensitivity which plays a crucial role in enhancing the welding process.

This functionality provides a smooth transition between different current levels and ensures that you have better control of the welding process.

Limitations of a Corded TIG Foot Pedal

Despite the amazing functionality and features of a foot pedal, it does come with some potential drawbacks.

One limitation that everyone has to face is the wire clutter. Foot pedal adds to the wire clutter in your workplace. It significantly restricts your movement and creates a potential tripping hazard.

Hence, you have to stay mindful of the cable at all times or you might trip or damage it.

Adding to this, welding has lots of risks for the welder as well as other items that are in the world’s place. The wire of the foot pedal is more susceptible to wear and damage.

Furthermore, to reduce the clutter in the work area, foot pedals were made more compact with slim designs and thinner wires, but that only made them more susceptible to damage.

A damaged foot pedal or cord presents you with various problems. You won’t be able to use it effectively and may lose control of the amperage. Repairing the damage or replacing the foot pedal can also be very expensive.

These limitations can make the welding process a bit cumbersome and limit your productivity. That’s why the modern world came up with the wireless foot pedal for TIG welders.

Alternatives to TIG Foot Pedal

The foot pedal is not the only tool that helps you control amperage in a TIG welder. You can also use various other tools for controlling the amperage.

1. Handheld Amperage Control

You can get a control device that has a finger or thumb switch which allows you to control the welding current without using a foot pedal.

This is quite beneficial when you are TIG welding in tight spaces where you can’t use a foot pedal because it would not be possible to maintain a steady foot position.

2. Torch-Integrated Foot Pedal

Modern TIG torches also feature the built-in amperage control that allows the welder to adjust the current directly on the torch.

This feature offers much more immediate control and is also very suitable for tight spaces. However, it is not as effective as a foot pedal.

How to TIG Weld Without Foot Pedal? – Using Lift Start

If you don’t have a foot pedal or the high-frequency start feature in your welding machine, then the arc won’t start on its own.

Although you can alter the amperage and control it directly from the machine, which is a bit slower but still a viable method, you won’t be able to start the arc which presents a significant challenge.

That’s where lift starts. You can use this feature to start the arc and then the TIG welding process.

It is just as it sounds. You lift the tungsten electrode from the base material to start the arc because no matter how many times you push the button, the arc won’t start.

So, you will have to touch the base metal softly with the electrode and then lift it away slowly as the arc starts, and then you can start the welding process.

But, as we have discussed several times, TIG welding is susceptible to contamination. So, why would anyone touch the electrode to base metal?

Well, you are not touching the weld pool but the cold base metal to start the arc, which doesn’t contaminate anything.

This method is used when welding electronic devices like TV or computers. Using high-frequency features to start the arc can mess with this equipment. So, the lift start method is recommended and used.
