If you plan on using an economy water-cooler, you need
to set the selector to the OFF position since the economy
cooler does not communicate with the welding machine.
The second line (Unit) allows you to switch the machine
from the Imperial system to the Metric system. For
instance, wire speed changes from IPM to m/m and
material thickness changes from SAE decimals to
millimeters.
The third line allows you to switch between the spool
gun and the internal wire feeder. With the Pro Pulse 300,
you have the option to run steel wire on the internal wire
feeder while running aluminum on a spool gun. If you
have a dual tank cart, you can have both gas cylinders
(the one for mild steel and the one for aluminum)
hooked up at the same time. The machine also allows
you to keep the spool gun plugged in at the same time
you have a MIG welding gun connected. With this
function, you can switch back and forth between the two
guns in no time! All you need to do is switch the
software and the Dinse plug to the correct positions/
settings (the control plug and the gas hose stay
connected).

The fourth line allows you to restore the default factory
settings of the Pro Pulse 300. You can use this function
if a third party made adjustments that cannot be tracked
any longer.
MIG 4T
The selection and setup of MIG 4T works identically to
MIG 2T. The only difference is trigger function. In MIG
2T, pressing and holding the trigger makes the weld, and
releasing the trigger stops the weld. In MIG 4T, pressing
the trigger makes the gas flow, releasing the trigger
makes the weld start, pressing the trigger again makes
the weld stop, and releasing the trigger again makes the
gas stop. The procedure is the same when welding mild
steel, stainless steel, silicon bronze, flux-cored, as well
as every other kind of welding wire.
Attention:
The 4T trigger is reprogrammed for
ALL
pulsed aluminum programs. We assigned a hot start
function to the initial pull. Please read

Aluminum with the Pro Pulse 300
(
Pages 11-13
) to
fully understand the hot start function.
Spot Welding
Pro Tip: Don
’
t use any slope down with spot or stitch
timers unless you are aware of the consequences and
are certain that is your desired weld procedure.

Press and release button
A
(

) until the LED next
to
SPOT
illuminates, and then press button
E
(
Fig. 4
) to
access the menu. The new screen (
Fig. 35
) gives you the
option to adjust the duration of the spot weld. Turning
right encoder
G
(
Fig. 4
) incr eases or decr eases the
time. Keep in mind that the start speed and the start time
should be set to 100% and 0.1 seconds initially. You
may then experiment with the settings to find those that
achieve the best results. If the trigger is pressed and
held, the machine makes a spot weld exactly as long as
the spot timer is set for. After the timer runs out, the
machine stops automatically.
Stitch Welding

STITCH
illuminates, and then press and release

(

) lets you adjust Time ON and Time OFF for
stitch welding.
