Preparing welding system for use

Before starting the use of the welding equipment

Ensure the installation has been completed
Switch the welding equipment on
Prepare the cooler
Connect the earth return cable to the work piece
Connect the voltage sensing cable to the work piece if applicable (available with Pulse+ power source)
Calibrate the welding cable (in MIG operation mode only)

>>  Refer to Calibrating welding cable for instructions.

Turning on welding system

To turn on the welding equipment, turn the power source main switch to ON (I).

Turn the main switch to start and shut down the welding equipment. Do not use the mains plug as a switch.

If the welder is left unused for a longer period, detach the mains plug to disconnect it from the mains.

Preparing cooler

Fill the coolant container inside the cooler with Kemppi cooling liquid. For instructions on filling the cooler, refer to Filling cooler and circulating coolant. To weld, you must pump the coolant through the system by pressing the coolant circulation button in the front panel of the cooling unit.

Connecting earth return cable

Keep the welding piece connected to earth to reduce the risk of injury to users or damage to electrical equipment.

Attach the earth return cable clamp on the welding piece.

Ensure that the surface contact to the table is clean of metal oxide and paint and that the clamp is firmly secured.

Selecting operation mode and process

To select the operation mode (MIG/TIG/MMA/Gouging), refer to Using X5 Manual control panel or AP/APC control panel: Device settings, depending on your equipment setup.

Replace also the welding cable accordingly, and remove or replace the filler wire in the wire feeder.
For TIG welding, the polarity (+/-) must be switched. The polarity can be selected by connecting the welding current cable and earth return cable accordingly to either the positive or negative connectors on the power source.
