When doing repair welding on your unit take precaution
attaching your ground to the component being repaired. This
will reduce the chance of arcing through a bearing, cylinder,
etc., damaging the component. Paint should be removed
from the surface to be used as the “ground” (earth).
WELDING INSTRUCTIONS
Always have a fire extinguisher on hand in case of fire. Ade-
quate ventilation and dry area are necessary. Protective
clothing should be used and all persons in the welding area
should have protection for their eyes. Follow instructions for
welding and cutting on paint.
AWS CLASS E7018 Low hydrogen rod for normal repairs
on low alloy to medium carbon steel. All position welding,
good penetration, and crack resisting up to 80,000 yield.
Also suitable for repair of previous intershield welds.
AWS CLASS E11018G Low hydrogen rod for repair on
high strength alloy steel such as T-1, 80,000 to 100,000
yield. All position welding, good penetration, and high ten-
sile strength up to 110,000.
Use necessary precaution when welding around fuel tanks,
oil reservoir, batteries, tubing and pressure systems.
When welding close to glass, cylinder rods, or any polished
surface, provide adequate protection from splatter.
Never weld when the engine is running. Always disconnect
the battery cables and applicable grounds before welding.
Note: Low hydrogen rod E7018 must be used within four
(4) hours upon removal from a freshly opened con-
tainer or from a storage oven.
Low hydrogen rod E11018G must be used within 1/
2 hour upon removal from its container or from a
storage oven.
Do not weld on wet surfaces since this will cause hydrogen
embrittlement of the weld.
All welding procedures and welding operator qualifications
shall be in accordance with ANSI/AWS D14.3 when weld-
ing on load sustaining members (ANSI/ASME B30.5)
Before welding on the unit, contact the factory service de-
partment for approval.
