manual abstract
• The REMOTE display will be lit when a remote pot/control is detected. These Output Control configurations can be overridden (switched) with the CONTROL push button. When changed, the unit will power up in the configuration it was in when it was last powered down. 7. WELD MODE SELECT - FACTORY AND CONSTRUCTION (See Figure B.1) The Mode Control button selects from the following welding modes. CC-STICK SOFT: The Stick Soft process features continuous control ranging from 5 to 425 amps. This mode was intended for most SMAW applications, and Arc Gouging. • Arc Gouging: Setting the output of the Stick Soft mode to 425 amps will enable the arc-gouging mode. The actual output current will depend on the size of carbon used. The recommended maximum size carbon is 5/16". • The Hot Start control regulates the starting current at arc initiation. Hot Start can be adjusted from minimum (0), with no additional current added at arc start, to maximum (10), with double the preset current or 425 amps (max of machine) added for the first second after arc initiation. • 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. CC-STICK CRISP:The Stick Crisp mode features continuous control from 5 to 425 amps. This mode was intended primarily for pipe welding applications. • The Hot Start control regulates the starting current at arc initiation. Hot Start can adjust starting current up or down by 25% of the preset value. The recommended setting for Hot Start is 5 where the initial current is equal to the preset 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. TIG GTAW: The TIG mode features continuous control from 5 to 425 amps. The TIG mode can be run in either the TIG touch start or high frequency (optional equipment required) assisted start mode. • The Hot Start control selects the starting mode desired. A setting of less than 5, the TIG lift start mode is selected. The OCV is controlled below 10v and the short circuit "TIG touch" current is maintained at 25 amps independent of the preset current. When the tungsten is lifted, an arc is initiated and the output is regulated at the preset value. Hot start settings between 0 and 5 regulate the arc initiation current. A setting of 5 results in the most positive arc initiation. A setting of 0 reduces hot start. • Hot Start settings between 5 and 10, select high frequency assisted starting TIG mode. In this range, the OCV of the machine is controlled between 50 and 70 volts. If using the Lincoln K930-1 TIG Module, set the Hot start to 10 for maximum OCV. • The Arc Control is not used in the TIG mode. TIG SOLENOID OPTION The Solenoid only operates when the V350 is in the TIG mode. If the Weld Terminals are in “Remote” then the solenoid will open when the arc start switch is closed. The solenoid will close after the arc switch has been opened and the post flow time expired. If the Weld Terminals are turned “ON”, then the solenoid will open when the electrode is touched to the work. The electrode needs to remain in contact with the work to allow for gas coverage before attempting to start the arc. The solenoid will close after the arc has been broken and the post flow time expired. CV-WIRE: The CV-WIRE mode features continuous control from 10 to 40 volts. The mode was intended for most GMAW, FCAW, and MCAW applications. • The Hot Start control is not used in the CV-WIRE mode. • The Arc Control regulates pinch effect. At the minimum setting (-10), minimizes pinch and results in a soft arc. Low pinch settings are preferable for welding with gas mixes containing mostly inert gases. At the maximum setting (+10), maximizes pinch effect and results in a crisp arc. High pinch settings are preferable for welding FCAW and GMAW with CO2. CV-INNERSHEILD: The CV-INNERSHEILD mode features continuous control from 10 to 45 volts. This mode was designed for self-shielded flux cored wires that require tight voltage control. • The Hot Start control is not active in the CV-FLUX CORED mode. • The Arc Control regulates pinch effect. At the minimum setting (-10), minimizes pinch and results in...
