PARAMETERS
PURPOSE
1-9
The unit has 9 programs which allow the operator to select parameters and hen save the
settings to the selected program channel. To operate, use the selector button to select the
desired program number where the program is to be assigned. The red select light will be lit,
indicating that the welder is in the programming mode. Enter the desired program parame-
ters. After all parameter changes have been made, press the selector button and hold for 3
seconds and release. The green save button will light, indicating the function has been saved.
After approximately 2 seconds, the save light will go out, and the unit will default back to the
red select light. Any additional adjustment made after this will need to be resaved.
Normal,
The welder includes two Easy Start Up modes, one for AC and one for DC. The Easy Start Up
AC and DC
features for AC and DC have been pre-programmed with parameters that are generally usa-
ble in most situations. Most parameter adjustments are blocked and are non adjustable in
these modes. Amperage and control functions are adjustable. Select Normal to allow stand-
ard setup. Suited for quick welds and repairs or novice use.
0-25 Seconds
Pre-Flow sets the gas flow time before the arc starts after the trigger or pedal is pressed.
Used to purge the torch and flood the weld area with shielding gas so the arc start is stable
and weld is free from porosity. Use enough time so that first blast of argon is settled (usually,
about .3-.5 seconds). Note: Preflow will delay the arc start by the amount of time set.
120V:
Serves as the 2T/4T initial amp value at the time of arc initiation while using the foot pedal,
5-120A (AC/DC)
torch switch or amptrol. This allows the arc to be initiated at a different amp value than the
240V:
selected maximum or minimum welding amps. Typically, this used to start the weld puddle
5-250 A (AC/DC)
more quickly. This feature is usually turned to the minimum amp setting (5 amps) while the
foot pedal is in use. However, it can be used to create a "hot" start with the pedal to remedy
starting issues at low amperages with larger tungsten and resolve heat dissipation issues.
