The repairing principle of the welding machine should be made by our company and
the user can solve the problems met in using it under the direction of our company.
1. Issues to pay attention
(1)
It should rivet the tag of equipment number on the shut of the casing, or the inner
elements might be damaged.
(2)The connection between the welding cable and the connecting terminal of the
welding machine should be solid and reliable. Otherwise, the terminal can be burn
out which will result in the unstableness of the welding process.
(3) To keep the bare copper parts of the welding cable and the connecting terminal of the welding
machine from the metals on the ground to avoid the short-circuiting of the welding
machine output.
(4) To avoid the damage or break of the welding cables and the control cables.
(5) To avoid the deformation of the welding machine caused by being stroken. Do not
stack heavy load on the welding machine.
(6) To keep being ventilated.
