MULTI-PROCESS PANEL FUNCTIONS

Weld Mode

Setting the Weld Mode is selecting the proper program from the ones available in the machine’s memory for a particular welding application. The table on the right side of the front panel (See Figure B.2) gives information on the different programs available in this machine. It describes the type of process (CV, CC, synergic GMAW), type of metal (mild steel, stainless steel, alu- minum), type of shielding gas and size of electrode rec- ommended for a particular mode.

The Weld Mode selection is enabled by toggling the SELECT switch until the LED next to Weld Mode is lit. A Weld Mode number will be displayed on the display meter. Toggling the SET switch up or down will increase or decrease the WELD MODE number displayed. The machine will change to the selected weld mode after two seconds of SET switch inactivity. If the SELECT switch is changed before two seconds of SET switch inactivity, the machine will not change modes. The last active Weld Mode will be saved at power down so that it will be selected with the next power up of the machine.

Preflow / Postflow

•The Preflow setting allows a time to be selected for shielding gas to flow after the trigger is pulled and prior to wire feeding and establishing an arc.

•The Postflow setting allows a time to be selected for shielding gas to continue to flow after the trigger is released and output current is turned off.

•The Preflow timer will be selected by toggling the SELECT switch until the LED next to PREFLOW /POSTFLOW is lit. The display meter will read Pre. The present Preflow time will be displayed and can be changed by positioning the SET switch up or down.

•The Postflow timer will be selected by pressing down the SELECT switch an additional time. The LED next to PREFLOW / POSTFLOW will remain lit; but the dis- play meter will now read Pos. The present Postflow time will be displayed and can be changed by position- ing the SET switch up or down.

•The default value for both Preflow and Postflow is "OFF" (0 seconds).

•Preflow can be adjusted from 0 to 2.5 seconds in 0.1 second increments.

•Postflow can be adjusted from 0 to 10.0 seconds in 0.1 second increments.

Run-In

•The Run-In function offers the ability to set a wire feed speed, from trigger until an arc is established, that is inde- pendent of the Welding or Start wire feed speed. Setting a Run-In WFS lower than the welding WFS avoids stubbing problems when starting the arc.

•Run-In is selected by toggling the SELECT switch until the LED next to RUN-IN is lit. A Run-In WFS may be adjusted using the SET switch on the Multi-Process Panel. The Display meter on the Multi-Process Panel will indicate the run-in speed. Do not use the Output Control Knob on the upper case front to adjust the WFS. This will change the welding WFS displayed in the meters on the upper case front.

•The default value for Run-In is "OFF."

•Run-In speed is adjustable from 50 ipm to 150 ipm (Inches per Minute).

Start Procedure

This machine provides the option of setting a Starting Procedure to start the weld, and from there, to ramp to the welding procedure over a specified amount of time. Typically starting on a higher starting procedure than the welding procedure is known as a “Hot Start”. Setting a start- ing procedure lower than the welding procedure is known as a “Cold Start”.

For SMAW (Stick) welding setting a “Hot Start” helps to minimize stubbing the electrode.

For GTAW (TIG) welding setting a “Cold Start” minimizes burn-through of thin materials when not using a manual amperage control.

For Wire Feed welding using a start procedure can help improve starting characteristics. A good example is when welding aluminum. Aluminum’s high thermal conductivity results in heat spreading around the plate very fast. Therefore more energy is necessary at the very beginning to heat up the starting point of the weld. Once the welding begins, it is not necessary to give this extra heat anymore so a ramp down to the welding procedure is necessary.

To set a Start Procedure begin by using the SELECT switch to select the Start LED. Using the SET switch, enter the desired Start ramp time duration (its available values range from 0.01 seconds to 0.50 seconds in increments of 0.01 seconds or the default value of OFF). This value will be dis- played on the digital meter of the multiprocess panel (See Figure B.2).

After setting the Start time also set the WFS, and voltage/trim. The way to know what information needs to be entered is to look for flashing LED’s. If an LED is flashing that parameter value needs to be entered.
