What does a Footswitch do?

You will get efficient and thoughtful service from kacon.

Footswitches are used to operate machines or devices. Compressing a footswitch will often turn a device or machine off or on depending on the application and circumstance. They are a type of switch and are used to either make or break an electrical circuit.

Footswitches can be either momentary or latching. Momentary means that the footswitch must remain compressed to carry out its function, for example sewing machines will require continuous compression for the machine to remain switched on. Latching means that the footswitch can be pressed once, the user can then remove the pressure on the switch but the device or machine will remain on until the switch is compressed again. Often used for tattoo machines or lathes.

What does a Footswitch do? Application Examples:

Footswitches are used within many industries such as the medical industry, health and beauty, Industrial processes as well as common place applications. Within these industries footswitches can operate different devices, they are;

· Sewing machines

· Press iron machines

· Lipo suction devices

· Patient hoists

· Medical equipment

· Hair removal applications

· Optical instruments

· Dentist chair controls

· Medical beds

· Tattoo machines

· Industrial machinery

· Machinery controls

· Stapling machines

· Packaging machines

· Cutting machines

· Soldering machines

Benefits of using Footswitches

Footswitches are usually selected for use because:

· They are space saving as they are on the floor and off the work desk.

· Footswitches are more hygienic than hand controls as they are not passed from person to person.

· They also offer hands free operation so the user can multitask.

Welding operator comfort is a key part of success in TIG welding. It results in better maneuverability and can lead to improved productivity — and ultimately, better weld quality.

Operators are often restricted by the length and cumbersome nature of the cords and leads required to lay a weld with their TIG torch. These elements slow movement around weld cells, clutter the floor, and create impediments to safety and productivity.

One technology eliminates or reduces these challenges and improves welding operator comfort and control, while also helping to reduce operational and labor costs: wireless TIG foot controls. They also provide numerous benefits for quality, productivity and safety.

Challenges impacting welding performance

Foot pedals are commonly used to control amperage during TIG welding. However, traditional corded foot pedals can limit operator mobility, result in more clutter in the work area, and become a common source of downtime for repairs that are required when cords become damaged. There are several common challenges that can occur when using a corded foot pedal in TIG welding.

 In order to maintain flexibility, foot control cords are relatively thin, making it easy for them to be damaged in the work space. For example, cords can be damaged by sharp edges on tables, benches, stools — even the workpiece itself. Damage can occur when the cord is dragged across these edges during repositioning, or when a heavy work table or supply cart rolls over the cord. Contact with hot parts in the welding cell, such as recently completed welds or the nozzle of the TIG torch, is also a frequent cause of cord damage.

Damage to the foot control cord can result in a loss of connection, meaning the welding operator no longer has control via the foot pedal. This can cause downtime and increased costs for repair — or even require the replacement of the entire remote unit. Cord repair and replacement costs can add up to hundreds of dollars over the life of the product.

In addition, the more cords being used in the welding operation, the greater the clutter in the work space and the potential for cord tangling. Using a corded foot pedal means there are three cords necessary — with the addition of the work lead and the TIG torch cord — for each machine. Not only can these cords be potential trip and fall hazards for operators, they can also result in increased frustration and time spent on cord management (e.g., untangling). 

Reducing the time spent winding and unwinding cords each day can improve productivity and efficiency.

Consider a wireless solution

Because of the aforementioned issues, cord care and management can be a time-consuming and costly issue for fabricators, manufacturers and welding shops. Wireless foot controls provide a solution.

Wireless foot pedals have a transmitter in the base of the control that communicates with the receiver on the front of the power source. Wireless foot pedals operate in the same manner as traditional wired foot pedals; the only difference is they do not require a control cord.

Eliminating the need for a foot pedal control cord offers numerous benefits.

• Less downtime and money is spent on cord repair and maintenance.
• Operators save time they would otherwise spend untangling, winding and unwinding the control cord — often up to 10 to 15 minutes daily, or over 50 hours per year.
• Clutter in the work area is reduced, which in turn lessens the opportunity for trip or fall injuries.

In addition, eliminating the need for the control cord helps improve welding operator comfort, by eliminating the need for awkward positioning to reach the workpiece and/or maneuvering involved with too short of a cord.

As with any wireless technology, there are some limitations to the foot controls for TIG welding. When welding takes place inside a metal enclosure, such as a boiler pressure vessel or the hull of a ship, for example, the wireless signal may not transmit well if there is not a large enough opening for the signal to travel through.

Wireless technology works best when the spot of the weld is kept relatively within the line of sight of the power source. Under these conditions, some wireless foot controls can work up to a 90 feet from the power source (although with TIG welding, distance is often limited by the length of the TIG torch cable).

There are some steps to overcome these line-of-sight issues and still reap the benefits of having wireless control at the point of the weld. These include using a 14-pin control cord extension, which expands the reach of the wireless receiver while still providing mobility and point-of-use control in the immediate welding environment.

There are some additional considerations when choosing wireless foot controls. Some manufacturers offer remote foot controls that use standard batteries that are easy to change without the need for tools. Look for these options to simplify battery changeover and reduce costs.

In addition, consider choosing wireless foot controls that are designed to prevent signal interference and that can be automatically paired with the machine — and stays paired with the same unit until paired with another receiver. This automatic capability allows users to easily pair a foot pedal with their machine even if they are not sure which control it was paired to before — even when there are many wireless foot controls and machines in the work space.

Reap the benefits of wireless foot control 

Even small improvements in production can add up over time. Wireless foot controls offer a return on investment by helping to improve productivity and efficiency in TIG welding operations — eliminating the time and money spent on control cord repairs and failure, reducing weld clutter in the work space, and improving operator comfort and mobility.
