Operation Power-up Sequence GTAW – This is a CC (constant current) weld mode used for the GTAW tig welding process. When power is applied to the Flextec 350x CE, the SMAW – This is a CC (constant current) weld mode displays will illuminate and the machine electronics will used for the SMAW stick welding process. - Page 19 Hot Start Dial Amperage Display Meter The Hot Start control regulates the starting current at arc initiation. Hot Start can be set to ‘0” and no additional current is added at arc start. Increasing from 0 to 10 will increase the additional current (relative to the preset current) that is added at arc initiation.
- Page 20 Thermal Light VRD Lights There are two indicator lights on the case front of the This status light indicates when the power source has Flextec 350x CE above the Voltage display to indicate been driven into thermal overload. If the output terminals the status of VRD operation.
