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

•

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, depending on the model, switch or turn the power source main switch to ON (I).

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

If the machine 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 and bleed the cooler before use. For instructions on filling and bleeding the cooler, refer to Preparing cooler.

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 work 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 work piece.

Ensure that the contact surface 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), refer to Using control panel.

For TIG welding, the polarity (+/-) must be switched. For information, refer to Changing welding polarity.

In MMA welding, the VRD (Voltage Reduction Device) limits the open-circuit voltage to 24 V.
