ENGINE COOLING SYSTEM

WARNING

Air to cool the engine is drawn in the base sides and exhaust through radiator & case back. It is important that the intake and exhaust air is not restricted. Allow a minimum clearance of 0.6m (2 feet) from the case back and 40cm (16”) from either side of the base to a vertical surface.

------------------------------------------------------------------------

BATTERY CONNECTION

CAUTION

Use caution as the electrolyte is a strong acid that can burn skin and damage eyes.

------------------------------------------------------------------------

The machine is shipped with the negative battery cable disconnected. Make certain that the RUN-STOP switch is in the STOP position. Attach the negative battery cable to the negative battery terminal and tighten using a 13mm socket or wrench. It may be helpful to remove the coolant over-fill bottle. Pull up on bottle to remove from bracket.

NOTE: This machine is furnished with a wet charged battery; if unused for several months, the battery may require a booster charge. Be careful to charge the bat- tery with the correct polarity.

MUFFLER OUTLET PIPE

Using the clamp provided secure the outlet pipe to the outlet tube with the pipe positioned such that it will direct the exhaust to the radiator end of the machine. Tighten using an adjustable wrench.

SPARK ARRESTER

Some local laws may require that gasoline or diesel engines be equipped with exhaust spark arresters when they are operated in certain locations where unarrested sparks may present a fire hazard. The standard muffler included with this welder does not qualify as a spark arrester. When required by local regulations, a suitable spark arrester, such as the K1898-1 must be installed and properly maintained.

WARNING

An incorrect spark arrestor may lead to damage to the engine or adversely affect performance.

------------------------------------------------------------------------

REMOTE CONTROL

The machine is equipped with a 6-pin and a 14-pin connector. The 6-pin connector is for connecting the K857 or K857-1 Remote Control or for TIG welding, the K870 foot Amptrol or the K963-3 hand Amptrol. When in the CC-STICK, DOWNHILL PIPE, or CV- WIRE modes and when a remote control is connected to the 6-pin Connector, the auto-sensing circuit auto- matically switches the OUTPUT control from control at the welder to remote control.

When in TOUCH START TIG mode and when a Amptrol is connected to the 6-Pin Connector, the OUTPUT dial is used to set the maximum current range of the CURRENT CONTROL of the Amptrol.

The 14-pin connector is used to directly connect a wire feeder control cable. In the CV-WIRE mode, when the control cable is connected to the 14-pin connector, the auto-sensing circuit automatically makes the Output Control inactive and the wire feeder voltage control active

WARNING

NOTE: When a wire feeder with a built in welding voltage control is connected to the 14-pin connec- tor, do not connect anything to the 6-pin connec- tor.

MACHINE GROUNDING

Because this portable engine driven welder creates its own power, it is not necessary to connect its frame to an earth ground, unless the machine is connected to premises wiring (home, shop, etc.)

To prevent dangerous electric shock, other equipment to which this engine driven welder supplies power must:

WARNING

•Be grounded to the frame of the welder using a grounded type plug.

•Be double insulated.

•Do not ground the machine to a pipe that carries

explosive or combustible material.
