The eld rocess elector witch is used to set the desired weld mode. The Flextece 450 has 4 selectable welding modes: O This is a CC (constant current) weld mode used for the SMAW stick welding process. O This is a CC (constant current) weld mode used for the GTAW TIG welding process. O This is CV (constant voltage) weld mode used for welding the GMAW MIG welding process and the FCAW-GS, flux cored gas shielded welding process. nnershield O This is a CV (constant voltage) weld mode used for welding the FCAW-SS, flux cored self shielded welding process The Flextece 450 is also capable of gouging. Gouging can be done in either the SMAW mode or the CV and CV-Innershield modes. In addition to the weld process selector switch, a hot start toggle, output control dial and arc control dial are provided to setup and fine tune the welding procedure. Weld Process Selector Switch 4 Position switch used to select the welding process. Hot Start Toggle Switch The Hot Start control regulates the starting current at arc initiation. Hot Start can be set to . ff. and no additional current is added at arc start. When set to the . n. position, additional current (relative to the preset current) is added at arc initiation. Arc Control Dial Full range selection of arc control from -10 to +10. In CV mode, this control is an inductance control. In stick mode, the control adjusts the arc force. Output Control Dial Output control is conducted by a single turn potentiometer. (Adjustment is indicated by the meters.) When in Remote Mode, this control sets the maximum welding current of the remote device. For example, full depression of a foot or hand amptrol results in the preset level of current. Voltage Display Meter • Prior to CV operation (current flow), the meter displays desired preset voltage value. • Prior to STICK or TIG operation, the meter displays the Open Circuit Voltage of the Power Source or four dashes if the output has not been turned on. • During welding, this meter displays actual average volts. • After welding, the meter holds the actual voltage value for 5 seconds. The displays blink indicating that the machine is in the "hold" period. • Output adjustment while in the "hold" period results in the "prior to operation" characteristics. I Amperage Display Meter • Prior to STICK or TIG operation (current flow), the meter displays preset current value. • Prior to CV operation, the meter displays four dashes indicating non-presettable AMPS. • During welding, this meter displays actual average amps. • After welding, the meter holds the actual current value for 5 seconds. The displays blink indicating that the machine is in the "hold" period. •Output adjustment while in the "hold" period results in the "prior to operation" characteristics Weld Terminals On/Remote Toggle Switch • This switch determines the trigger location. • When set to the “. position, the weld terminals are at OCV (open circuit voltage) and ready to weld. • When set to the “. position, output is enabled through a remote trigger. Control -Local/Remote Toggle Switch • Set the switch to . ocal. to control output at the machine by the Output Control dial. • Set the switch to “. to control output via a remote device (K857 hand amptrol or K870 foot amptrol) connected to the pin remote connector or a wire feeder connected to the 14-pin connector. Thermal Light • This status light indicates when the power source has been driven into thermal overload. If the output terminals were "ON", the output will be turned back on once the unit cools down to an acceptable temperature level. If the unit was operating in the "! mode, the trigger will need to be opened before or after the thermal has cleared and closed after the machine has cooled down to an acceptable temperature to establish output. This weld mode is a constant current (CC) mode featuring continuous control from 15 i 500 amps. It is intended for the SMAW stick welding processes and arc gouging. Hot Start The Hot Start control regulates the starting current at arc initiation. Hot Start can be set to “Off. and no additional current is added at arc start. When set to the “On. position, additional current (relative to the preset current) at arc initiation. Arc Control The Arc Control regulates the Arc Force to adjust the short circuit current. The minimum setting (-10) will produce a "soft" arc and will produce minimal spatter. The maximum setting (+10) will produce a "crisp" arc and will minimize electrode sticking. eld erminals n emote O Set to . n. so the machine is in the ready to weld state. oltage isplay eter O This display will display three dashed lines when the machine is in the idle state. This indicates that voltage is not settable in this weld mode. While output is enabled, the actual welding voltage is displayed. After welding, the meter holds the actual voltage value for 5 seconds. Output adjustment while in the "hold" period results in the "prior to operation" characteristics. The displays blink indic...
