Troubleshooting - IMS FLEX 280A CEL Manual De Instrucciones

Operating :
• Manual remote control (option ref. 045675)
The remote control enables the variation of current from 50% to 100% of the set intensity. In this configuration, all
modes and functions of the machine are accessible and can be set.
• Pedal (option ref. 045682) :
The pedal control enables variation of the current from the minimum set current to a 100% of the set intensity.
In TIG mode, the machine will only operate in two-stage welding (2T mode). The upslope and downslope are not
automatic, and are controlled by the User with the foot pedal.
