Specifications
The XTM 503si, Is a compact type machines with integrated wire
feed units for use with three phase 400V supply. The machine uses
inverter technology to allow MIG , TIG and MMA welding to be
performed.

4.0 Description of Controls
1. VOLTAGE DISPLAY INDICATOR: It will be display Arc-Force
preset in MMA, and display voltage preset in MIG/MAG, and
display real-voltage when the welder is working.
2. POWER INDICATOR: When the machine is turned on, the
power indicator will be on.
3. ALARM INDICATOR: When the thermal indicator is on, it shows
the machine is overloaded and the internal temperature is too
high. Weld output will turn off automatically but the fan will still
be working. When the internal temperature is decreased, the
overload light will turn off and the machine will be ready to weld
4. OUTPUT INDICATOR, when illuminated the output power is on.
5. CURRENT/WIRE SPEED DISPLAY displays the wire feed
speed or the welding current depending upon the feature
selected.
6. LEFT ADJUST KNOB: Its main function is adjusting welding
current in MMA mode; and the final current setting in 4T mode
(craterfill)
7. MIDDLE ADJUST KNOB: Its main function is adjusting Arc-
Force in MMA, and adjusting welding voltage in MIG/MAG. for
the crater fill.
8. RIGHT ADJUST KNOB: Its main function is adjusting the
inductance in MIG welding, low inductance allows the current to
surge during dip transfer, high inductance gives stability during
spray transfer.
9. MIG MODE SELECTOR, this button toggles between the
Manual MIG Welding mode and the synergic MIG welding
mode.
10. TRIGGER MODE. 2T operation is when the trigger is
depressed and held in for the duration of the welding cycle. 4T
mode allows the trigger to be pressed and released. At the end
of the weld pressing the trigger in again and holding activates
the Craterfill current until the trigger is released.
11. WELD FUNCTION SELECTION BUTTON: Users can select
MMA or MIG/MAG function by this button, and the indicators at
the left part of button will indicate the selection weld function.
12. MIG/MIG WIRE DIAMETER SELECTION BUTTON: Users can
select wire diameter by this button, and the indicators at the
left part of button will indicate the selection wire.(only applies in
Synergic mode)
13. MIG/MAG GAS SELECTION BUTTON: Users can select
shielding gas by this button. (only applies in Synergic mode)
14. GAS PURGE BUTTON, purges the shielding gas when
depressed.
15. Remote control for the Welding current (synergic mode) or the
wire speed (manual mode)
16. Remote control for the arc /-( synergic mode) or the Arc
Voltage (manual mode)
17. Wire loading button
