SAFETY PRECAUTIONS

WARNING

Unless an optional output control or contactor is used with the LN-25, the electrode circuit (including welding wire, wire drive and welding gun) is electrically hot when the welding power source is on. The gun trigger controls wire feed only.

Disconnect or shut off welding power source before making connections or installations to the LN-25.

Welding gun should be stored in the insulated gun holder, located near the rear on the top of the LN-25 case, to avoid accidental arcing.

The LN-25 should be positioned upright on a horizontal surface.

WARNING

ELECTRIC SHOCK can kill.

•Do not touch metal portions of the LN-25 lead clip when welding power source is on.

POWER SOURCE CONNECTION

The LN-25 can be used with any DC welding power source. A constant voltage power source is recommended; however, the LN-25 can also be used with a constant current power source as long as the open circuit voltage is less than 110V DC.

CAUTION

Do not use LN-25 models below Code 9200 with any TIG or Square Wave welding power sources. Do not use LN-25 models equipped with internal contactors with non- Lincoln TIG or Square Wave welding power sources. Damage to the LN-25 circuit can occur as a result of the high output inductance typically associated with these power sources. TIG high frequency power should never be applied to the LN-25.

If not using an LN-25 Remote Output Control option (See Remote Output Control Options and Cable Assemblies Section), the power source output must be electrically “hot” at all times when the power source is turned on.

See the power source instruction manual for proper power source connections and setting required.

WARNING

ELECTRIC SHOCK can kill.

•Do not operate with covers removed.

•Turn off power source before installing or servicing.

•Do not touch electrically hot parts.

•Turn the input power to the welding power source off at the fuse box before working in the terminal strip.

•Only qualified personnel should install, use or service this equipment.

DC-250

a. Connect a jumper from 2 to 4 on the power source terminal strip so the output will be energized when the DC-250 is turned on.

b. Connect electrode cable to the “Innershield/ GMAW” output terminal of polarity required by electrode. Connect work lead to other “Innershield/GMAW” output terminal.

c.Place “Set to CV Electrode Cable Polarity” switch at appropriate position.

d.Place power source toggle switch in “Output Control at DC-250” position, unless a Remote Control is connected to 75, 76 and 77 on the DC- 250 terminal strip.

e.Place mode switch in “Innershield GMAW (CV)” position. Set CV arc control to “2” (or “NORMAL” on some machines). Initially set the output control on “7”.

DC-400 AND CV-400

a. Connect a jumper from 2 to 4 on the power source terminal strip so the output will be energized when the power source is turned on.

NOTE: DC-400 machines above Code 9200 have an output toggle switch to perform this function.

b. Connect the electrode cable to the output terminal of polarity required by electrode. Connect work lead to other output terminal.
