Part 3: Simple test for powering on the machine
Reboot RBM2000P Welding machines will be subjected to strict various tests when they leave the factory to
ensure that each welding machine that reaches the user is of high quality, because our machine has to go through
tens of thousands of kilometers of long-distance transportation from the factory to the delivery to you. It’s inevitable
that some uncontrollable factors will cause some internal components of the machine to become loose or even
damaged in the process. We recommend that you check the external device as soon as you get the welder, and turn
on the power to check to ensure that you receive It is a qualified product.
Precautions for power-on inspection:
1、Please make sure your power supply voltage is 220+-15%. Reboot RBM2000P just supports 220V input voltage.
if you have a generator power supply, please ensure that the generator is not less than 6000w.
2、It is recommended to choose 30A circuit breaker protection when input voltage is AC 220V.
3、Please choose the power plug that suits your local electrical law requirements.
4、Extension cord: #12 AWG or larger; 25’ (8m) or shorter.
Turn on the power switch of the machine and the fan on the back of the machine rotates, and the digital
display on the panel indicates that the power is normal.
Note:
1) The digital display shows irregular changes at the beginning, and then returns to the digital display after 3
seconds, which is normal.
2) In order to reduce the working temperature of the machine, it is normal for the fan to continue to rotate for a
few seconds after the power is turned off.
3) During high-strength continuous welding, machine protection may occur. After continuous heat dissipation, the
machine will return to normal, which is normal.
Attached table: Self-examination of abnormal conditions without response when turning on the machine:
1. The machine's power switch is not turned on.
2. The power input voltage is wrong.
3. The power plug is loose.
4. The internal circuit is loose (due to long-distance transportation, bumps), you need to open the cover and
check the internal connection line.

Part 6: Machine operation guidance.
Tips:
1. Wear a welding helmet fitted with a proper shade of filter to protect your face and eyes when welding or watching;
2. Wear approved safety glasses. Side shields recommended;
3. Use protective screens or barriers to protect others from flash and glare; warn others not to watch the arc;
4. Wear protective clothing made from durable, flame-resistant material(wool and leather) and foot protection;
5. Use approved ear plugs or ear muffs if noise level is high;
6. Never wear contact lenses while welding.

3、To adjust the current, ARC FORCE and HOT START.
If the parameters stored in the welding machine are not required to be changed, the welding machine can
directly start welding after starting up. Otherwise, the welding machine shall be adjusted by steps 1, 2 and 3.
1. Press the welding mode selection button to select MMA welding mode.
2. Adjust knob A to set welding current I.
2. Adjust knob B to set the arc force.
4. Start welding.
All parameters adjusted by steps 1, 2, and 3 will be automatically saved after the start of welding, and still
remain unchanged even if the machine is shut down in the middle .
There are three adjustable parameters for manual covered-electrode welding:
1. Current: 30 - rated current for welding. Please select the appropriate current according to the process.
2. Arc force: the arc force shall be determined according to electrode diameter, sett current and process
requirements. If the arc force is large, the droplet transfer will be fast and it is not easy to stick the electrode;
however, if the arc force is too large, the spatter will increase; if the arc force is small, there will be
little spatter and the weld appearance will be good, but arc will be soft or it is easy to stick the electrode.
The arc force shall be increased especially when the thick electrode is used in the lowe current welding.
3. Hot striking arc current (HotI): 10-100A, Press A first, the MENU indicator light is on, turn the A knob, when
“HotI”is displayed on the digital display on the left, turn the B knob, you can adjust the value of the hot
start.
Note:
1) The welding rod specification supported by Reboot RBM2000P is below 4.0(5/32in), usually 2.5(3/32in) and
3.2(1/8in). European style generally uses E6013, American style generally uses E7018, and stainless steel
generally uses ER308.
2) It supports welding of 1-8mm(1/64-5/64in) carbon steel and 1-5mm(1/64-7/32in) stainless steel. Aluminum
can not be welded. For carbon steel, please use carbon steel electrode. For stainless steel, please use
stainless steel electrode.
3) Connect the ground clamp to clean bare metal. No rust, paint or other coatings, and ensure good electrical

Version Number: RBM2000P-20210517A1
10
conductivity.
4) The ideal distance between the welding rod and the welding object is 1-2mm(1/64-5/64in), to ensure that the
welding rod and the workpiece are in continuous and stable contact. The welding rod should not be too high
or pressed too low to avoid arc breaking and adhesion.
5) It is normal for novices to have adhesion during the welding process, and you can try to friction arc to avoid
adhesion.
6) Suitable for ordinary welding rods, such as 7018, 6013, etc., but not suitable for special welding rods, such as
7010, 7011.
Possible problems
1) There is no arc, check the ground wire to connect the workpiece to ensure that there is no rust, paint or other
coatings on the workpiece.
2) There is no arc, check the direct distance between the welding rod and the welding object, the ideal distance
is 1-2 mm; check whether the welding object has rust or oil stains, it is recommended to polish with sandpaper
or a grinder.
3) When welding, the spatter is very big, and it feels very difficult to weld. Please try to change the polarity
connection of the ground wire clamp and the welding clamp with the machine.
4) During the welding process, if the time exceeds 3 minutes, overcurrent protection may occur. You need to stop
working for a few minutes, let the machine cool down for a period of time, and automatically recover. If the air
cools for more than 10 minutes, the machine does not automatically recover, please shut down and restart.
5) If you have any problems that cannot be solved, please contact us at .
MIG mode
Reboot RBM2000P provides two welding modes: gas shielded welding and self-shielded welding with fluxed
wire. If you are working at home or in a studio, in order to ensure a better welding effect, it is recommended that you
use the gas welding mode; if you need to go out to work, carry gas cylinders and other inconvenient situations, you
can use the Self-protected welding method.
A) Common gas shielded arc welding and gasless self-shielded welding
1、Select “MIG/CO2 or MIG/MIX ” process.
