Version Number: RBM1550-20210414A1
Operation Manual
Reboot RBM-1550 welding machines adopts the latest pulse width modulation (PWM) technology and insulated
gate bipolar transistor (IGBT) power module, which can change work frequency to medium frequency so as to
replace the traditional Transistor transformer with the medium frequency transformer. its characterized with portable,
small size, light weight, low consumption and etc. It is also an intelligent and easy-to-operate multi-function welding
machine with MMA, MIG GAS, MIG GASLESS and LIFT TIG. It has the characteristics of strong welding
performance and diversified usage scenarios. It can be used in both gas and gasless conditions, and the welding
effect is excellent. It is highly praised by welding enthusiasts. It is also very friendly to beginners in welding and can
quickly get started.
Part 1: Machine Introduction
1. MIG/MMA/LIFT TIG function selection.
2. Current display meter.
Digital ammeter is used to display preset current and
actual output current.
3. 220V, voltage input indicator light.
4. 110V, voltage input indicator light.
5. Fault light, overheating and overcurrent protection
light.
6. Spool gun and MIG gun switch
7. Small range voltage adjustment
It is recommended that the voltage does not need to
Be adjusted. The machine is a unified machine. The
voltage, current and wire feeding speed are
automatically matched. Only when the deviation is
too large, it can be adjusted
appropriately.
8. Adjust the current and wire feed speed knob
Turn clockwise to increase the current, turn
counterclockwise to decrease the current.
9. MIG welding torch connector
10. Spool gun control socket
11. Positive terminal
Positive Terminal. Welding current flows from the power source via heavy duty bayonet type terminals. It
is essential, however,that the male plug is inserted and turned securely to achieve a sound electrical
connection.
12. Polarity conversion socket.
13. Negative terminal
Welding current flows from the power source via heavy duty bayonet type terminals. It is essential,
however, that the male plug is inserted and turned securely to achieve a sound electrical connectionć
14. Polarity slection plug
In MMA and LIFT TIG state, this plug does not need to be connected; in MIG gas welding state, this plug
is connected to positive terminal 11; in MIG airless welding state, this plug is connected to negative
terminal 13.
