Kemppi Machine Remotes FAQs
Practical answers on setting up, using and looking after hand remotes, foot pedals and torch controls for TIG welding machines.
Do I need to switch my machine into a remote mode before a foot pedal or hand remote will work?
On many machines, yes. Plugging the remote in is often not enough: the machine may need to be told to take its current control from the remote, either with a front-panel setting, a menu option or by pressing the pedal for a few seconds. Some machines detect the remote automatically.
If the pedal does nothing, check the machine's manual for its remote or pedal setting before suspecting a fault. Also confirm that the plug and socket match and that your machine supports a remote at all, because not every machine does. Always follow the instructions for your own machine and remote.
Should I use 2T or 4T trigger mode with a foot pedal?
With a foot pedal you hold the pedal down to weld and release it to stop, which matches the 2T (press to start, release to stop) trigger logic. 4T is a latching mode where you press and release the trigger to start and press and release again to stop, so the arc keeps running with no hand or foot held down. That does not suit a pedal that has to stay pressed.
Most machine makers therefore tell you to set 2T when using a pedal. Some machines handle this automatically or have their own behaviour, so check the manual for your machine and remote.
Why is a foot pedal so useful for aluminium and thin material?
Aluminium conducts heat away quickly, so it often needs more current to start the pool, then less as the work warms up. Thin sheet and edges also overheat quickly. With a pedal you can start with more heat, ease back as the metal warms and taper off at the end, all without stopping or reaching for the machine.
That helps you hold a steady travel speed and bead shape and reduces the risk of burn-through. A pedal is not essential for every job, and many welders also practise without one so they learn what current a given thickness needs.
What is the difference between a simple on/off torch switch and a remote that controls current?
A basic torch switch only tells the machine to start and stop the arc. A remote current control, such as a pedal, hand remote or a control in the torch handle, also sends a variable signal that sets the current between the minimum and your maximum. They usually use different wiring and connectors, so a plain switch cannot give current control.
Designs with the on/off switch and current control in the handle are often preferred to foot controls. Whether a given control works with your machine depends on the machine's socket and wiring, so check the manual and data plate.
