3.1 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" on the next page 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" below. 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" on page74 or "Auto
control panel: System settings" on page90, depending on your equipment setup.
As applicable, replace also the welding cable accordingly, and remove or replace the filler wire in the wire feeder.
3.1.1 Filling cooler and circulating coolant
Fill the cooler with 20-40 % coolant solution, for example, Kemppi cooling liquid.
