Component Identification and Explanation
Setting the Unit Up For Welding Manually
ed setting will default back to the Voltage.
6.
Pre
-
Flow. The unit has an adjustable pre
-
gas flow setting. This
automatically times the flow of gas before the weld, improving
overall weld quality at the critical start of the weld. However, the
user may opt to turn down this setting if desired Use the left Up
and Down navigation keys to navigate and highlight (turn green)
this setting. Use the left adjustment knob to turn the setting on
or off. In Flux
-
Cored mode, this feature will be unavailable and
be listed as N/A.
7.
Post Flow. The unit has an adjustable post
-
gas flow setting.
This is complimentary to the Preflow setting and also serves to
improve the weld quality and prevent oxidation after the weld is
terminated and also serves to provide gun cooling. However,
the user may opt to turn down this setting if desired Use the left
Up and Down navigation keys to navigate and highlight (turn
green) this setting. Use the left adjustment knob to turn the
setting on or off. In Flux
-
Cored mode, this feature will be una-
vailable and be listed as N/A.
8.
Inductance. This improves the wet in of the weld. A low setting
will result in a very poor arc, with a high pitch. The result will be
a raised ridge in the middle and poor wet
-
in. Excess spatter may
be observed. The result of too high of a setting will result in a
very fluid, flat puddle. The pitch will be raspy and not smooth.
Starts will not be as smooth Generally a setting of 65 to 75% is
a good starting point on Steel with C25. With Steel and C100,
70 to 80% is a good starting point. Generally pure CO2 is not
very smooth on many welders, but with inductance control, high
quality welds can be achieved. Stainless requires the highest
inductance with 90% or greater. Aluminum can range depend-
ing upon the wire from 60 to 80% or so. Flux
-
Core behaves a
little differently with a 40 to 50% starting point. Of course, dif-
ferent weld positions, joint designs and thicknesses of metal can
affect the inductance requirement slightly. Use the left Up and
Down arrow keys to navigate and highlight (turn green) the Burn
Back control. Use the left side control knob to change the value.
9.
Burn Back. This is the amount of time the arc stays on after the
wire stops feeding. It is used to help prevent the wire from stick-
ing in the weld and to reduce the need for constant trimming of
the wire before restarting. Use a setting of .1 to .3 seconds to
begin with for most applications. Smaller diameter wires need
less burn back time. Use the left Up and Down navigation keys
to select and highlight (turn green) the Burn Back feature. Use
the left adjustment knob to adjust the duration of the Burn Back.
10.
Spot Timer. This is a timer that can be set to automatically shut
off the weld when the trigger is held down. This allows you to
make repeatable and perfectly sized tack welds or short seams.
Use the Right side Up and Down navigation keys to navigate and
highlight (turn green) the Spot Timer. Use the right side adjust-
ment knob to turn the Spot Timer on and set the duration of the
spot timer. NOTE: Keep in mind that If the spot timer is turned
on accidently, the wire feed will stop suddenly soon after the
trigger is pressed. In fact it may barely feed and just seem to
quit if the time is set low. This is normal, but often a source of
tech support calls. If your wire feeder stops feeding unexpect-
edly after the trigger is pressed, check this function first.
11.
Stitch Timer. This function works only in conjunction with the
Spot timer. This provides a continuous
“
on/off
”
action of the
spot timer, allowing the user to move smoothly and evenly
space spot welds along a seam or around a part, providing
“
stitches
”,
or a series of tack welds. The time set is the length of
“
OFF
”
time between the Spot cycles. The trigger will be held
down and the spot/stitch cycle will continue until the trigger is
released unless the unit is being used in 4T mode in which case
the trigger will be pressed and released and the cycle will begin.
A second press of the trigger will be required to terminate the
cycle. (See next item for 2T/4T explanation.)
12.
Torch Trigger Function. This controls how the welder reacts to
the torch trigger. In 2T, the trigger is pressed and held to weld.
In 4T, the trigger is pressed briefly to start the arc, then released
to continue to weld. The weld is continued without the torch
trigger being held down. The trigger is once again pressed, held
and then released to terminate the arc.
13.
Torch Type. Select between the main MIG gun or Spool Gun
function.
THE STICK MANUAL SCREEN
1.
Welding Voltage. In Stick Mode, the Voltage is not adjustable
due to the nature of stick (Constant Current) welding. The volt-
age varies according to the length of the arc. The Voltage dis-
played while idling is the Open Circuit Voltage (OCV) of the
machine. While welding this changes to reflect the actual arc
voltage.
