REMOTE CONTROL
The remote control operates in TIG and MMA mode.
Connector technology
The CEL 250A TRI is equipped with a female socket for remote control. The specific 7 point male plug (product
ref.045699) enables connection to a manual remote control (RC) or foot pedal (PEd).
For the cabling layout, see the diagram below.
Connecting
1- Power up the machine
2- Plug the pedal/remote control to the connecting socket on the machine.
3- The screen will flash and display « No » (Nothing),
4- Select the type of control using keys :
« No » (Nothing) / « RC »  (Remote Control) / « PEd »  (Pedal)
5- After 2 seconds the display will freeze on the chosen selection, then displays the welding current.
NB: In case of error, unplug the remote control, (« No » will be displayed) and re-start the connection process.
Remark: Remote type choice will be required each time the machine is powered up.
Functions
Manual remote control (ref.045675) / Pedal (ref.045682):
The remote control enables the variation of current from minimum intensity (DC: 10A / MMA: 10A) to an intensity
defined by the user.
In this configuration, all modes and functions of the machine are accessible and can be set.
THERMAL PROTECTION & DUTY CYCLE
• Thermal protection: thermal protection indicator turns on and the cooling time is about 2 to 5 min according to
external temperature.
• Leave the machine connected to the supply after welding in order to let it cool down
• The welding unit describes an output characteristic of "constant current" type. The duty cycles following the norm
EN60974-1 (at 40°C on a 10mn cycle) are indicated in the table here below :
