5.0 Installation

Read entire installation section before starting installation.

SaFetY preCautIOnS

• ELECTRIC SHOCK can kill.
• Only qualified personnel should perform this installation.
• Only personnel that have read and understood the Operating 

Manual should install and operate this equipment.
• Machine must be grounded per any national, local or other 

applicable electrical regulations.
• The power switch is to be in the OFF position when installing 

work cable and electrode cable and when connecting other 

equipment.

5.1 Unpacking the Machine

Carefully remove the machine from the packaging, we recommend  

you retain the packaging until the machine has been fully installed 

and tested incase it has been damaged in transit and has to be 

returned to the re-seller.

5.2 location

Be sure to locate the welder according to the following guidelines:
In areas, free from moisture and dust. 
Ambient temperature between 0-40

0

C.

In areas, free from oil, steam and corrosive gases.
In areas, not subjected to abnormal vibration or shock.
In areas not exposed to direct sunlight or rain.
Place at a distance of 12” (300 mm) or more from walls or similar 

that could restrict natural airflow for cooling.

5.3 Input and grounding connection 

WarnInG

Before starting the installation, check that your power supply 

is adequate for the voltage, amperage, phase, and frequency 

specified on the Machine nameplate.

Operate the welding power source from a three-phase 50/60 Hz, 

AC power supply. The input voltage must match one of the electrical 

input voltages shown on the input data label on the unit nameplate. 

The XTS-203 MMA machine should only be used on 400V supply. 

Refer to the specifications table for voltage tolerances. 
Have a qualified electrician connect the input plug. For long runs 

over 30m , larger copper wires should be used. The green/yellow 

wire in the input cable connects to the frame of the machine. This 

ensures proper grounding of the machine when the machine plug is 

inserted into the receptacle.

5.4 Output polarity Connections

Electrode polarity
MMA electrodes are generally connected to the ‘+’ terminal and the 

work lead to the ‘-‘terminal
But if in doubt consult the electrode manufacturer’s literature.
IF TIG welding the torch should always be connected to the ‘-’ 

4.0 Description of Controls

1) ON OFF Switch for switching on or off the mains supply to the 

machine. Note the output of the machine is permanently on unless 

the on/off switch is in the off position. (Mounted on the rear of the 

machine)
2) Fault light This indicates a fault or over temperature condition with 

the machine refer to the fault finding section for further information 

3) Power light This indicates mains power is applied to the machine 

and that the machine is currently switched on when the light is 

illuminated 
4) MMA/LIFT-ARC selector switch Used to select between MMA 

welding mode and Lift-arc TIG welding. 
5) Display selector switch, toggles the display from Amps to Volts
6) Output Display, shows the output amperage or voltage dependent 

upon the position of the switch (5) 
7) Output power connection  + (Positive) this is the 50mm Dinse 

connection socket for the positive welding lead.
8) Arc force control this alters the penetration of the arc and allows 

the operator to fine tune the arc characteristics, the arc force function 

will operate when the arc length is reduced buy pushing the rod 

close to the plate, at which time the weld current will be increased.
9) Hotstart, this function gives a temporary boost to the welding 

amperage when first striking the electrode to prevent sticking to the 

work.
10) Output power control for adjustment of the power out put of the 

machine in LIFT-TIG or MMA mode
11) Output power connection - (Negative) this is the 50mm Dinse 

connection socket for the connection of the negative welding lead.
