Fronius Machine Remotes FAQs
Practical answers on pedals, hand remotes and extension cables for TIG and stick welding machines of this type.
Why does a pedal help on thin metal and aluminium?
A pedal lets you change the current while the arc is running, so you can start with more heat and then ease off as the work warms up. Thin sheet is the obvious case: you back off the pedal as the metal heats, which reduces the risk of burn-through.
Aluminium soaks up a lot of heat before the weld pool forms, so many welders start with more current and then reduce it along the joint. On a fixed current you would have to stop and change the setting instead.
Set the machine's maximum to the job first, then use the pedal for fine control below it.
Why do the 2-step and 4-step torch modes disappear when I plug in a remote?
On many machines a connected pedal or hand remote takes over the start/stop and current control from the torch trigger, so the trigger modes are greyed out or unavailable while the remote is detected. Spot modes can be affected in the same way.
This is normal behaviour, not a fault. Unplug the remote and the trigger modes normally return. Which modes are affected, and whether a remote symbol shows on the display, depends on the machine, so check the machine's operating instructions and the instructions that come with the remote.
What should I know about a wireless pedal: pairing, range and batteries?
Typically you switch the pedal on, switch the machine on and enable its wireless function, then confirm the pedal on the machine display. Check the identifier printed on the pedal matches the one the machine shows, so you pair the right unit.
Range is limited. One maker quotes up to about 10 metres in a straight line with nothing in the way, and metal fabrications and other interference can reduce it. Pedals normally run on ordinary batteries, and a weak or flat battery can leave the status light off, so keep spares. Wait a few seconds after switching the pedal off before switching it on again, as the maker advises, so the switch-off is detected.
How should I check and route a remote's cable?
Before each use, with the equipment disconnected, look along the lead for cuts, fraying or heavy scuffing, check the plug for a cracked cover or bent pins, and make sure the cable is held firmly where it enters the plug. HSE guidance on portable electrical equipment lists these user checks. Do not repair a damaged lead with tape; take the item out of use and have a competent person repair or replace it.
Route the lead so it is not a trip hazard and is less likely to be damaged, away from hot metal, sharp edges and vehicle routes. Keep the pedal cable clear of your feet and of the work.
