Maintenance Welding To The Weld-Deck - Vanguard CPW 125-4-S Series Operation And Maintenance Manual

Maintenance Welding to the Weld-deck

Do not use the welding power units on a weld-deck to perform any welding on the same weld-deck. The use of welding
power units on one weld-deck to perform welding on a different weld-deck is permissible.
Do NOT use electrical components (ECM or sensors) or electronic component grounding points for grounding the welder.
Do not attempt to start or run the weld-deck genset with the main ground at the rear of the control/distribution center
disconnected.
Turn off the engine. Turn the battery disconnect switch to the Off
(O) position.
Note: Welding must only be done with Engine Control Module
(ECM) connectors and power supply connects disconnected.

DISCONNECT THE ECM BEFORE WELDING.
Always completely disconnect and isolate the main ground at the
rear of the control/distribution center—at point "A" or at point
"B"—prior to welding on the equipment.
Ensure that all of the precautions covered in the Fire Prevention
and Explosion Prevention section of this manual have been
followed. Take adequate precautions to ensure that a fire will not
occur as a result of welding. Always have an appropriate, fully
charged fire extinguisher at hand when performing any welding.
Clamp the ground cable from the welder to the component that
will be welded. Place the clamp as close as possible to the weld.
Protect any wiring harnesses and components
from the debris and the spatter which is created
from welding.
Ensure that the ECM connectors and power
supply connects are
completion of welding on the machine.
Ensure that the main ground at the rear of the
control/distribution center—point "A", point
"B"— has been reconnected after completion
of welding on the machine.
