6-5. Lift-Arc TIG Procedure

1 2

1 − 2

“Touch” Seconds

With Mode Switch in the Lift-Arc TIG position, start an arc as follows:

1TIG Electrode

2Workpiece

Touch tungsten electrode to work- piece at weld start point, hold electrode to workpiece for 1-2 seconds, and slowly lift electrode. An arc will form when electrode is lifted.

Normal open-circuit voltage is not present before tungsten electrode touches workpiece; only a low sensing voltage is present between electrode and workpiece. The solid-state output contactor does not energize until after electrode is touching workpiece. This allows electrode to touch workpiece with- out overheating, sticking, or getting contaminated.

Do NOT Strike Like A Match!

6-6. Recommendations For Extreme Cold Weather Operation

.For more information on operating in cold

weather, contact the nearest Factory Au- thorized Service Agent or Kubota Service Center.

Fuel

DUse an arctic-grade diesel fuel and keep fuel tank at least half full to prevent fuel lines from draining back into tank.

DDo not use gasoline or kerosene.

DDo not use fuel additives.

Oil

DUse 10W30 oil when operating at ambient temperatures above -4°F (−20° C).

DUse 5W30 oil when operating at ambient temperatures above -13°F (−25° C).

DOperating at extremely low temperatures thickens engine oil and reduces cranking speed. Contact a Factory Authorized Ser- vice Agent or Kubota Service Center for information on using 0W20 oil in these conditions. Low temperature oil must be replaced as ambient operating tempera- tures increase.

Coolant

DBe sure the cooling system is completely filled with a 50/50 antifreeze/water mix (open the radiator vent when filling). Do not mix antifreeze and water solution in the overflow tank. Use a premixed 50/50 antifreeze/water solution to “top off” over- flow tank. Use caution if rerouting cooling lines. Engine damage due to lack of coolant or incorrect coolant mix is not covered by the warranty.

DA 50/50 antifreeze/water mix protects en- gine to -34°F (−37° C). If operating at even lower temperatures, contact a Factory Authorized Service Agent or Kubota Ser- vice Center for coolant information.

Battery

DReplacement Battery Rating: 12 Volt, 535 CCA (minimum) 90 RSV Group 55.

DCheck connections at battery, starter, and engine block. Inspect battery cables for abrasion and wear, and verify the battery is secured.

DConsider installing easily-accessible bat- tery booster leads (0 or 00 AWG) to pro- vide easy connection to a service truck’s battery.

DBoost the starting capability of the battery by using a battery heater.

Starting

DDo not use ether.

DUse the engine block heater to maintain engine temperature above ambient tem- perature.

DUse the glow plugs for 20−30 seconds be- fore starting. As a preseason check, make sure the glow plugs are working properly.

DDisconnect all unnecessary loads from generator ac receptacles when starting.

Operating

DTo reduce crankcase condensation and breather tube freezing problems, allow engine to reach normal operating temper- ature as quickly as possible.

DCrankcase breather tubes will collect condensation and freeze if the hose is im- properly routed. The breather tube should be free of sharp bends and kinks. A blocked breather tube will cause exces- sive crankcase pressure that will blow out the safety plug, oil seals, or dipstick. Con- tact a Factory Authorized Service Agent to obtain a shorter breather hose that is less likely to kink.

DInspect the routing and condition of the breather tube frequently. Reroute or re- place the hose if necessary.

DFor continuous use in extreme cold, block the cooling holes in the base to reduce air flow through the radiator and achieve higher engine temperature. Close off the base inlet vents only if the engine coolant or oil temperatures can be monitored to ensure they remain within the specified limits.

DTo obtain warmer air for combustion, turn the air cleaner inlet away from the inlet vents, and seal the inlet vents.

DIf operating in cold weather all the time, consider replacing the existing radiator cooling fan with a smaller fan that draws less air through the radiator. Operation in warmer temperatures would require an additional “booster” electric fan to ade- quately cool the engine.
