starting from the current indicated posi-

 

 

 

 

 

SPOT tion. Any parameter not available in the

 

 

 

 

 

 

mode selected is skipped over. If a

 

 

 

 

 

 

function is being displayed when the

 

 

 

 

 

 

Timer/Crater Select key is pressed,

 

 

 

 

 

 

then the light of the last parameter

 

 

 

 

 

 

 

 

 

 

 

 

selected before the function was cho-

 

 

 

 

 

 

sen will come on and become the start-

Top Left Light - indicates preflow time

 

 

 

 

 

 

is being displayed in seconds. This is

 

 

 

 

 

 

the time the shielding gas flows before

 

 

 

 

 

 

the wire feed and power source are

 

 

 

 

 

 

activated.

 

 

 

 

 

 

Top Right Light - indicates postflow

 

 

 

 

 

 

time is being displayed in seconds.

 

 

 

 

 

 

This is the time the shielding gas flows

 

 

 

 

 

 

after the wire feed and power source

 

 

 

 

 

 

are deactivated.

 

 

 

 

 

 

Middle Light - indicates that crater feed

 

 

 

 

 

 

speed is being displayed. Crater speed

 

 

 

 

 

 

is only available when 4-step trigger

 

 

 

 

 

 

with crater fill is selected. (See 4-step

 

 

 

 

 

 

trigger mode selection section). It is

 

 

 

 

 

 

activated by Step 3 and deactivated by

 

 

 

 

 

 

Step 4 of the 4-step sequence.

 

 

 

 

 

 

Bottom Light - indicates spot on time is

 

 

 

 

 

 

being displayed in seconds.

 

 

 

 

 

 

NOTE: if unit is not in spot mode then

 

 

 

 

 

 

this light will be skipped over in the

 

 

 

 

 

 

selection sequence.

 

 

 

 

 

 

Increase Arrow - key increases the

 

 

 

 

 

 

setting of the parameter selected to be

 

 

 

 

 

 

displayed, except Wire Feed Speed and

 

 

 

 

 

 

Volts/Trim which are controlled by the

 

 

 

 

 

 

encoder knobs.

 

 

 

 

 

 

Decrease Arrow - key decreases the

 

 

 

 

 

 

setting of the parameter selected to be

 

 

 

 

 

 

displayed, except Wire Feed Speed and

 

 

 

 

 

 

Volts/Trim which are controlled by the

 

 

 

 

 

 

encoder knobs.

 

 

 

 

 

 

Arrow Keys use the “Accelerating

 

 

 

 

 

 

Digit” method for setting changes,

 

 

 

 

 

 

where holding the arrow key causes

 

 

 

 

 

 

setting change rate to accelerate from

 

 

 

 

 

 

slow to fast. Releasing arrow key resets

 

 

 

 

 

 

to slow setting change.

Acceleration Selection

Pressing both the “Gas Purge” key and then the function select key at the same time causes the acceleration setting to be displayed. The display will indicate “A-X” where X will be a number from 1 through 5 with 5 being the fastest acceleration. This number can be adjusted using the arrow keys. To exit this function, press both these keys again or press any other key except the arrow keys.

Burnback Time Selection

If necessary, for higher wire feed speeds, Burnback time may be selected to prevent the electrode from sticking in the weld puddle at the end of the weld. Pressing both the Gas Purge key then the function select key at some time while displaying the acceleration setting per above, press the function select key a second time to dis- play the Burnback time selection. Default is “b0” which is zero delay. Selecting “b1" thru “b5" selects delays from 10m sec to 50m sec in 10m sec increments. To exit this function, press both these keys again or press any other key except the arrow keys.

Selection of English or Metric Speed Display Units

Pressing both the Gas Purge key and then timer select key at the same time causes the speed display units to toggle between IPM (no decimal point displayed) and m/m (a decimal point displayed). If the speed dis- play units were IPM, then they will change to m/m. If the speed display units were m/m, then they will change to IPM. If the display is showing the volts/trim or one of the timers when the keys are pressed, the display will be changed to weld speed to indicate the selected speed display units.

Run-In Selection

Pressing both the Gas Purge and Cold Feed keys at the same time causes Run-In func- tion to toggle on or off, as indicated by the Run-In indicator light turning on or remaining off in the function select sequence.

As shipped, the Run-In function is off with a fixed setting of min. rated speed. Therefore, the Run-In indicator light will not sequence with the function select key, but the fixed setting will still be used for actual Run-In speed.

Activation of adjustable Run-In speed using the above dual key press, will permit Run-In speed to be adjusted with the arrow keys and the Run-In indicator light will return to the function key sequence. Re-pressing the above dual key again removes the Run-In light from the function key sequence, but replaces the fixed Run-In speed with the adjusted Run-in speed setting, until read- justed.
