you should see the little arrow behind the % sign move
from the first line in the display down to the second
line in the display. Now, turning encoder G will
change the arc force value. For an explanation of what
Hot-Start and Arc-Force are and what they do, please
refer to the Glossary at the back of the manual.
In order to start welding, either press home button B ,
or wait 5 seconds for the machine to revert back to the
welding screen. Now, strike an arc.
TIG Welding
Press and release button A to toggle through the menu
until the LED next to TIG illuminates. TIG refers to
DC TIG lift-arc ignition. This welding process requires
DCEN (electrode negative). Plug the ground clamp
into positive Dinse receptacle W ( Fig. 3 ), plug the
TIG torch into central connector X ( Fig. 3 ), and plug
supply cable V ( Fig. 3 ) into negative Dinse
receptacle Z ( Fig. 3 ). In order to initiate an arc and
vary the amperage while welding, a remote control,
such as a foot pedal or hand control, is needed. The
remote control needs to be plugged into the remote
control receptacle Y ( Fig. 3 ).
The TIG welding process typically uses 100% Argon
gas. Install the flowmeter supplied with your Pro Pulse
220 MTS on the tank and connect the flowmeter to the
machine with the supplied gas hose. To connect the
gas hose, fasten one end of the gas hose to the
flowmeter and the other to the back of the welding
machine. The gas hose needs to be connected to the
gas inlet on the back of the machine. These
connections need to be a bit more than finger tight, but
be careful not to over-tighten them. A 15-20 CFH flow
rate is a good starting point (although this ultimately
depends on the cup style and size). This machine uses
the same gas solenoid for MIG and TIG welding.
When the machine is turned on and in TIG mode, the
display will read an amperage number (e.g., 200 A).
By pressing and releasing button E , you can access the
setup menu ( Fig. 6; Note: The gear symbol refers to
setup. )
Fig. 4 shows a selected welding amperage of 100
amps. When you light an arc, the display will change
and display the accrual welding amperage and the arc
voltage.
In order to access the settings submenu, press button E
to show the following screen:

How to Weld—Step by Step
Stick Welding
Press and release button A (Select Mode) to toggle
through the menu until the LED next to Stick
illuminates. The Pro Pulse 220 MTS is now in stick
welding mode.
The LCD will show the welding amperage. Unplug the
male Dinse plug V ( Fig. 3) that supplies the welding
current to the MIG gun receptacle (central or Euro
connector), if necessary, and then plug the electrode
holder (stinger) into the desired outlet. Most stick
electrodes use DCEP, which requires the electrode
holder to be plugged into positive female Dinse
receptacle W ( Fig. 3) and the ground clamp into
negative female Dinse receptacle Z (Fig. 3 ). Then, use
encoder F to set your welding amperage.
The submenu in Fig. 5 allows you to select a Hot-Start
value for the stick rods. By turning encoder G , you can
change the hot start percentage to the desired setting. In
order to adjust the Arc-Force setting, press button C ;
