WORK CLIP LEAD

WARNING

ELECTRIC SHOCK can kill.

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

WARNING

IMPORTANT SAFETY NOTE: To avoid possible electrical shock, do not touch the metal portions of the LN-25™ work lead clip if the power source output is on. The clip will be electrically “HOT” to work if the input electrode cable to the LN-25™ is electrically “HOT” even if the gun trigger is off and even if an internal contactor is used. Care should be taken to only handle the LN-25™ work clip by its non-metal insulated portions and/or the welding power source should be turned off before handling the work clip.

The 15 ft work clip lead attached to the front panel of the LN-25™ case must be connected directly to the work using the spring clip on the end of the lead.

If not connected, the LN-25™ will not operate even if a K431-1 or K624-1 (42V) Remote Output Control option (refer to Accessories Section) is used. However, the electrode will still be electrically “HOT” when the clip lead is disconnected, if K431-1 or K624-1 (42V) Remote Output Control Option, or Internal Contactor (K443-1, 2 or3), is not used.

NOTE: The clip lead also serves as a work sensing lead for the LN-25™ Voltmeter (if installed). If the clip lead is extended by the user beyond the standard 15 ft. (4.6m) length, the voltmeter reading will be lower than the actual arc volts due to the LN-25™ motor control current flowing through the resistance of the extended lead. To minimize this voltmeter error, the following minimum lead size is recommended for the maximum extended lengths shown:

AWG	Maximum Length
#14	25	Ft (7.6m)
#12	50	Ft (15.2m)
#10	100 Ft (30.5m)
#6	200 Ft (61m)

REMOTE ARC VOLTAGE CONTROL (OPTIONAL)

This rheostat control allows you to control the power source output arc voltage level. Refer to K444, K444-1 and K444-2 Remote Voltage Kits in the Accessories

section.

GAS FITTING (OPTIONAL)

Provides gas output connection to the welding gun for the GMAW process. Refer to K430-1 or 2 Gas Solenoid Kit in the Accessories Section.

GAS POST PRE-FLOW TIMERS (OPTIONAL)

Allows for variable adjustment of gas pre-flow & post- flow at the start and end of the weld. Refer to K434-1 Gas Flow Timer Kit in Accessories Section.
