Miller Machine Remotes FAQs
Foot, fingertip, hand and wireless controls, plus extension and adapter cords, for this maker's TIG power sources.
How do I work out which remote and plug my machine needs?
Start with the machine's data plate and the remote socket on its panel. Count the pins and note the model and, where the maker splits a range by serial number, the serial number. Makers often supply the same type of remote with different plugs, and a change of connector part-way through a production run is not unusual, so a remote that looks right can still be the wrong version.
Compare those details with the maker's accessory list or manual for your power source. If the plug count does not match, a dedicated adapter cord may be the answer rather than a different remote. If you are unsure, our team can help you choose.
Why will my pedal only work with the torch switch in 2T mode?
A foot pedal holds the arc on for as long as you press it, so it behaves like a 2T (press and hold) trigger. Many makers state that the pedal needs 2T and will not work in 4T, and that you create the ramp-up and ramp-down yourself with your foot rather than relying on the machine's slope timers. Some designs do still allow a start current or upslope to be set on the machine, so this varies.
If your pedal does nothing, or the arc starts and stops oddly, check that the machine is set to 2T and that the remote option is selected. Your manual shows the exact menu or switch position for your model.
How do the remote and panel selector switches on the machine work?
Many TIG power sources have separate switches, or menu settings, that choose whether the output current and the output on/off are controlled from the front panel or from a remote. Maker manuals describe one switch for the current source and a second for the contactor. With no remote connected the contactor switch normally sits in the on position, and with a remote connected it is moved to the remote position.
If a newly fitted remote has no effect, these switches are the first thing to check. The labels differ between models, so follow the wording in your own manual.
How should I check my remote's cable and plug before use?
Before each use, with the equipment disconnected, look over the whole lead. The HSE's guidance on portable electrical equipment lists fraying, cuts or heavy scuffing, a damaged or loose plug, tape used to join leads, coloured wires visible where the cable enters the plug, and burn marks or staining as signs of trouble.
If you find any of these, take the remote out of use until a competent person has repaired it or it has been replaced. Do not carry on with a damaged lead. Pedals on a workshop floor take a lot of knocks, so check the cable where it leaves the pedal body as well as at the plug.
