2.0 Explanation of Warnings
There are several different warning symbols placed on the Miller Weldmaster T3. The symbols are
to alert the operator of potentially hazardous areas on the machine. Familiarize yourself with their
placement and meaning.
Caution: Unplug Machine
The “Caution: Unplug Machine” sticker is placed near
the opening of the cabinet and all access panels. To
prevent electrocution, the machine should always have
the power disconnected before the cabinet door is
open.
Caution: Electricity
The “Caution: Electricity” sticker is placed near areas
that contain electrical.
Caution: Read Document
Read accompanying documentation before use.

3.0 Electrical and Air Requirements
Warning! Only a qualified electrician may connect the electrical power.
Electrical Supply
Due to the number of different style outlets available, the cord will not include a plug. It
is recommended that your electrician install a plug that is compatible to your style power
outlet. You may choose to have your power cord hard-wired into your power supply. It
is recommended that your electrician use a junction box with an ON/OFF switch with
short circuit protection as required by local electrical code to be suitable for the primary
disconnect. The Miller Weldmaster T-3 requires the following power supply.
•16 Amperes - Single phase - 230 Volts
Shop Air Supply
The Miller Weldmaster T-3 includes an in-shop air supply valve that allows quick
connects and disconnects to your shop air supply. Due to the number of different style airline
connectors, a male quick-connect is not included. You will want to select a male
quick-connect with a ¼ inch NPT (National Pipe Thread) to match your female quick-connect.
The Miller Weldmaster T-3 requires the following shop air requirements:
•Minimum of 3 cfm at 120 psi (standard) or 85 liters/min at 8.3 Bar (metric)

4.0 Principals of Heat Sealing
CHAPTER 4 PRINCIPALS OF HEAT SEALING
Heat
Hot Air Heating System
The Heat required for the welding operation is created electrically by one heating element
located inside the Heat Element Housing. The Internal Air Compressor pumps air over the heat
element and carries the heat through the Hot Air Nozzle, applying the heat to the material to be
welded. The hot air temperature ranges from 25 to 730 Degrees Celsius (100 to 1350 Degrees
Fahrenheit).
Hot Wedge Heating System
The Hot Wedge heat system uses four cartridge heat elements to electrically heat the Wedge.
The Hot Wedge temperature ranges from 25 to 490 Degrees Celsius (100 to 915 Degrees Fahr-
enheit).
Speed
The Speed of the Weld Rollers determines the amount of time the heat is applied to the material
being welded. The slower the speed setting, the more the material will be heated. The faster the
speed setting, the less the material will be heated. To achieve the best weld, a minimal amount
of heat should be applied to the material while still achieving a full weld. Too much heat will
cause distortion of the material; while not enough heat will prevent the material from welding.
Pressure
The pressure of the weld roller is the final step when creating a weld. The pressure of the weld
roller compresses the heated material together completing the welding process.
Summary
When heat sealing, the correct combination of heat, speed, and pressure will allow you to
achieve a properly welded seam.

5.0 Definition of Controls
CHAPTER 5 DEFINITION OF CONTROLS
The manufacturer suggests that all operators are familiar with all the controls of their machine. It is in the
operators best interest to know the purpose of all these controls and their functions.
Start Button: The start button initiates the wedge swing and
motor controls. By depressing the start button the welding
process will begin.
Stop Button: The stop button will pause the welding operation.
By depressing the stop button the welding operation will stop.
Weld Roller Open/Close: The push/pull knob will open or
close the weld rollers. By pushing the knob the weld rollers
will close. By pulling the knob the weld rollers will open.

5.0 Definition of Controls
Emergency Stop Button: The emergency stop button will stop
the system operations in the event of an emergency. Depress
the emergency stop button in the event of an emergency. Twist
to release the emergency stop button.
Reset Button: The reset button turns power ON to the control
system of the machine. The reset button must be pushed
after the power disconnect has been turned ON and after the
emergency stop button has been turned and released.
Temperature Controller: The temperature controller is
used to set the desired temperature of the wedge. The
temperature range is 0OC to 430OC. The UP arrow increases
the set temperature, the DOWN arrow decreases the set
temperature. The EZ, scroll, and double circle buttons are used
for programming functions. The top display is of the actual
temperature and the bottom display is of the set temperature. If
the display is not showing the set and actual temperatures, turn
the power disconnect to the OFF position for 30 seconds then
back on again.

5.0 Definition of Controls
Pressure Gauge and Regulator: The pressure gauge and
regulator displays and controls the weld roller pressure. To
increase or decrease the weld roller pressure, pull the regulator
knob out then rotate. Rotate clockwise to increase the pressure
and counter clockwise to decrease the pressure. Push the
regulator in to lock the knob in place.
Speed Control: The speed control adjusts the speed of the
weld rollers. 0 is the lowest speed and 10 is the fastest speed.
Turn the knob to the desired speed setting
Drive Delay Control: The drive delay control delays the weld
rollers from starting until the start button or foot pedal has been
depressed. The drive delay control should be set to allow the
wedge to be in proper position before the weld rollers begin to
turn. Adjustment will be needed for individual products being
welded.

CHAPTER 5 DEFINITION OF CONTROLS
Power Disconnect: The power disconnect turns power ON/
OFF to the machine. For power to be turned ON rotate the
handle to the ON position and to turn OFF turn to the OFF
position. The power disconnect should always be turned
OFF when the machine is not in use or being serviced.
Foot Pedal Plug: The foot pedal plug connects the foot
pedal to the control system of the machine. Insert the
male end of the plug into the female end of the plug, then
tighten the threaded nut finger tight. The foot pedal should
be connected only when the machine is used in a stationary
mode.
Air Supply: The air supply should be connected to the
supply side of the ball valve, 1/4" NPT. The ball valve
should be turned to the horizontal position whenever the
machine is not in use and locked in the OFF position when
the machine is being serviced.
Foot Pedal: The foot pedal initiates the wedge swing and
motor controls. By depressing the foot pedal the welding
operation will begin.
