Lincoln Electric IM511-D manual Operating Instructions

OPERATING INSTRUCTIONS

Additional Safety Precautions

Always operate the welder with the roof and case sides in place as this provides maximum protection from moving parts and assures proper cooling air flow.

Read carefully the Safety Precautions page in the Instruction Manual before operating this machine. Always follow these and any other safety procedures included in this manual and in the Engine Instruction Manual.

Welder Controls - Function and Operation

Explanation of Symbols that Appear on this Equipment

ON OFF Low Idle High Idle

ENGINE “ON-OFF” Switch

When placed in the “ON” position, this switch energizes the engine ignition circuit. When placed in the “OFF” position, the ignition circuit is de-energized to shut down the engine.

ENGINE “START” Push-Button Switch

Energizes engine starter motor.

“POLARITY” Switch

Three STICK/TIG (constant current) polarity settings:

DC+, DC- and AC

Two wire feed (constant voltage) settings:

DC+ and DC-

NOTE: The setting of this switch must match the color band setting of the Range Switch (both switches must be set for the same welding process).

CAUTION

Never change the “POLARITY” switch setting

while welding. This will damage the switch.

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

“ RANGE” Switch

STICK/TIG (constant current)		6	45,90,120,
range settings			160,200,250
WIRE FEED (constant voltage)		3	LOW,MED,HIGH
range settings
	CAUTION

Never change the “RANGE” switch setting while

welding. This will damage the switch.

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

“ CONTROL”

Provides a fine welding current adjustment within the Range Switch settings in the STICK/TIG mode and welding voltage control with the Range switch set in the WIRE FEED mode.
