Connection of the LN-7 to the Weldmark 225

Shut the welder off.

Connect the LN-7 and the K240 contactor kit per instructions on the connection diagram S17742 (can be found in the back of this manual).

Place the “RANGE” switch to the “WIRE FEED” position and the “POLARITY” switch to the desired polarity.

Place the “IDLER” switch in the “HIGH” idle position. The engine idling device may not function when welding in the “WIRE FEED” mode.

Adjust wire feed speed at the LN-7 and adjust the welding voltage with the output “CONTROL” at the welder.

NOTE: If the output “CONTROL” is set below “3” the K240 contactor may not pull in.

Connection of K930-[ ] TIG Module to the Weldmark 225.

The TIG Module is an accessory that provides high frequency and shielding gas control for AC and DC GTAW (TIG) welding. See IM528 supplied with the TIG Module for installation instructions.

NOTE: The TIG Module does not require the use of a high frequency bypass capacitor. However, if the Weldmark 225 is used with any other high frequency equipment, the bypass capacitor must be installed - order kit T12246.

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 and understand all Safety Precautions before operating this machine. Always follow these and any other safety procedures included in this manual and in the Engine Owner’s Manual.

Auxiliary Power

The WELDMARK 225 can provide up to 8,000 watts of 115/230 volts AC, single phase 60Hz power for continuous use. The front of the machine includes three receptacles for connecting the AC power plugs; one 50 amp 115/230 volt NEMA 14-50R receptacle and two 20 amp 115 volt NEMA 5-20R receptacles.The CSA machine has one 50 amp 115/230 volt NEMA 14-50R receptacle and two 15 amp 115 volt NEMA 5-15R receptacles.

CAUTION

Do not connect any plugs that connect to the power receptacles in parallel.

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

Start the engine and set the “IDLER” control switch to the desired operating mode. Set the “CONTROL” to

10.Voltage is now correct at the receptacles for auxil- iary power.

115/230 Volt Dual Voltage Receptacle

The 115/230 volt receptacle can supply up to 35 amps of 230 volt power to a two wire circuit, up to 35 amps of 115 volts power from each side of a three wire cir- cuit (up to 70 amps total). Do not connect the 115 volt circuits in parallel. Current sensing for the automatic idle feature is only in one leg of the three wire circuit as shown in the following column.
