3）
Connect the ground clamp to clean bare metal. No rust, paint or other coatings, and ensure good electrical
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) During the welding process, the oc fault light is on, and it may be over-current protection. You need to stop
working for a few minutes, let the machine cool 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.
4) The OC light is on when the machine is turned on, please contact us.
