FlexiROC T30 R 20 Welding
136 No: 3629357835.1.3629419915 en-US
n Framework, brackets, and load-carrying structures are made of special materials. Any
repair welding performed using incorrect materials or additives can weaken the struc-
ture.
n Avoid welding close to bearings and bushings.
n Do not weld on the boom, hydraulic tanks, hydraulic cylinders, valve blocks, com-
pressed air tanks, or pressure lines.
n Do not weld on a FOPS/ROPS-approved cabin. The certification would then be invalid.
n Protect hoses, cables, and electric components.
n If possible, grind the surface of the weld smooth and treat it with anti-corrosion paint.
20.2 CAN Bus System Disconnection Before Welding
!
NOTE: The CAN bus and RCS can be severely damaged when welding.
NOTE: Consult Atlas Copco for approval of welding and choice of electrodes.
n Locate all modules present on the machine. Disconnect supply voltage to all modules,
both + (positive) and - (ground).
l Example of modules which can be present: application module, I/O module,
resolver module, and CS-module.
n Locate all sensors on the machine and disconnect them.
n Locate the safety controller and disconnect supply voltage, both + (positive) and -
(ground).
n Locate all panels included in RCS and disconnect supply voltage, both + (positive) and
- (ground).
n Remove the battery ground cable.
