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.

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.
