2.4 Positioning of the machine

Place the machine on a sturdy, level surface that is dry and does not allow dust or other impurities to enter the machines cooling air ow. Preferably site the machine to a suitable carriage unit so it is above oor level.

Notes for positioning the machine

• The surface inclination may not exceed 15 degrees.

• Ensure the free circulation of the cooling air. There must be at least 20 cm of free space in

front of and behind the machine for cooling air circulation.

• Protect the machine against heavy rain and direct sunshine.

NOTE! The machine is not allowed to be operated in the rain as the protection class of the machine,

IP23S, allows preserving and storing outside only.

NOTE! Never aim the spray of sparks from a grinding machine toward the equipment.

2.5 Connecting cables

NOTE! Always check before use that the mains cable, earth return cable and its clamp,

interconnection cable and shielding gas hose are in a serviceable condition. Ensure that connectors are correctly fastened. Lose connectors can impair welding performance and damage connectors.

2.5.3 Cable positions for multiple machine congurations

When using two or more FastMig X units working on the same work piece, the right positioning of voltage sensing cable and the earth return cable is important.

In order for the voltage sensing function to work properly, the earth return cable and the voltage sensing cable for each FastMig X power source should be connected close to each other and away from other units’ cables (see the pictures below).

2.5.4 Connecting to mains power

FastMig power sources are delivered as standard with 5 meters of mains power cable. No mains plug is tted at the Kemppi factory.

NOTE! If local country-based regulations state an alternative power cable is required, the mains

cable must be replaced in conformity with the regulations. Connection and installation of the mains cable and plug should only be carried out by a suitably qualied person.

Remove the machine cover plate to enable mounting of a mains cable. FastMig X 350 and X 450 power sources can be connected to the mains supply of 400 V 3~ .

If changing the mains cable take into consideration the following:

The cable is entered into the machine through the inlet ring on the rear panel of the machine and fastened with a cable clamp (05). The phase conductors of the cable are coupled to connectors L1, L2 and L3. The earth protection coloured green-yellow is coupled to the marked connector.

If you are using 5-lead cable, do not connect the neutral conductor.

L1 L2 L3

*) In S type cables there is a protective grounding conductor coloured green-yellow.

Generator use

If no mains connection is available, you can use FastMig X 350 and X 450 on a generator. The minimum recommended generator output is 35 kVA. The greater the output, the more stable is the FastMig X power source operation.

FastMig X 350, X 450

2.5.5 Cables

Kemppi always recommend the use of high quality copper cables with a suitable crosssectional area. Cable size should be selected depending on the intended welding application.

50 mm² copper cables may be used for low duty work in basic or synergic 1-MIG. However, using pulsed MIG/MAG process, longer cables, or higher welding power increase the voltage loss, and therefore smaller cross sectional interconnection cables and earth return cables will restrict the welding performance of your machine.

Recommended cross-sectional area of FastMig X power source cables: 70 – 90 mm².

The enclosed table shows typical load capacities and voltage loss values of rubber insulated copper cables for duty cycles 100%, 60% and 30%, when ambient temperature is 25 °C and the cable temperature is 85 °C.

Cable size 100 % 60 % 30 % Voltage loss / 10 m 50 mm² 70 mm² 95 mm²

Do not overload the cables due to voltage losses and heating.

NOTE! Always check the serviceability of the earth return cable and clamp. Ensure the metal

surface to which the cable is connected is clean from metal oxide or paint. Check the connector to the power source is fastened correctly.

2.5.6 Interconnection with wire feeder

Kemppi provide a choice of interconnection cable sets for dierent environments. Only materials that meet the demands of Kemppi's international markets are used in their construction.

Used correctly, Kemppi cable sets ensure high welding performance and serviceability. Before use, always ensure the cable set is in good condition and that connectors are correctly

fastened. Loose connections reduce welding performance and may result in damage to connectors due to heating eects.

For correct connection and conguration of cable sets, please refer to schematic drawings in section 2.5 of this manual.

NOTE! FastMig X 350 and X 450 power sources are designed to be used with WFX wire feed units.

4.5 Arc voltage display

FastMig X is capable of measuring and showing the voltage close to the welding arc. By taking this feature into use you don't need to be concerned about the voltage losses in welding cables anymore. With this feature you are only required to set the voltage for the arc before welding and after welding you can see the voltage close to the arc.

In order to use the arc voltage feature, follow these steps:

1. After setting up the welding equipment for the rst time, connect the voltage sensing cable to the welding piece and the measurement cable between the wire feeder and the power source.

2. If you are using a sub-feeder, enter the length of the sub-feeder to the SubFeederLength parameter.

3. Set the welding parameters according to your application. Note that the set voltage when using 1-MIG, MIG and WiseThin+ welding processes means always the voltage in the arc despite of ArcVoltage setting.

4. Weld with 1-MIG, MIG or with Pulse MIG for at least 5 seconds. During that time the welding machine calibrates itself for the welding cable length in question. Calibration values are stored into the welding machine, therefore this calibration is required only once after installing the welding machine package.

5. If you want to see arc voltage in panels during and after welding, turn the ArcVoltage setting to ON. Dot after voltage value in XF 37 or XF 38 panel means that showed value is arc voltage. In the weld data after welding in X 37 panel 'AVol' means also the arc voltage.

6. Voltage sensing cable can be removed after the calibration procedure, but it is recommended to use it always.

NOTE! Steps 1-3 should be repeated every time, when the length of the welding or grounding cable

is changed.

Factory PIN code is 0000 Administrator pin code change.

OFF: No PIN code inquiry. StartUp: Control panel X 37 always asks for the PIN code when the machine is turned on. Wire feeder panel XF 37 (or XF 38) is not aected and always works without PIN. Menu: Control panel X 37 asks for the PIN code every time when MENU button is pressed and when the display is in channel info mode (in start-up view). PIN code inquiry is made only once when entering the menu. After that the menu button can be pressed any time without PIN inquiry.

4.6 Welding software delivery prole

6. OPERATION DISTURBANCES

Should you experience a malfunction from your machine, please consult the basic troubleshooting text above rst, and complete some basic checks.

If the machine malfunction cannot be corrected with these measures, contact your Kemppi maintenance service workshop.

Operation of the overload protection

Yellow thermal protection lamp is lit when the thermostat is operating due to loading beyond the stated duty cycle.

The thermostat will operate, if machine is continuously loaded over rated values or cooling air circulation is blocked.

Internal fans will cool the machine, and when the pilot lamp is not lit the machine is automatically ready for welding.

Control fuses

Fuse, 6.3 A delayed, on the rear wall of machine provides protection for auxiliary devices. Use the same type and rating of fuse as marked beside the fuse adapter. Damage caused by

incorrect fuse selection is not covered by the guarantee.

Under and over voltages in the mains supply

Primary circuits of the machine are protected against sudden, transient overvoltages. The machine is designed to withstand 3 x 440 V voltage continuously. Ensure that voltage is kept within this permissible limit, especially when the mains supply is provided by a combustion engine generator. If the mains has under voltage (under approx. 300 V) or overvoltage (over approx. 480 V) machine control stops operation automatically.

Loss of a phase in the mains supply

Loss of a mains power phase causes noticeably poor welding properties. In some cases the machine won't start at all. Loss of a phase can be due to following:

• Blowing of mains supply fuse

• Defective mains cable

• Bad connection of mains power cable on machine terminal block or plug of machine.

FastMig X 350, X 450

7. MAINTENANCE

When considering and planning routine maintenance, please consider the frequency of machine use and the working environment.

Correct operation of the machine and regular maintenance will help you avoid unnecessary downtime and equipment failure.

NOTE! Disconnect the machine from the mains before handling the electrical cables.

7.1 Daily maintenance

• Check the overall condition of the welding gun. Remove welding spatter from the contact tip and clean the gas nozzle. Replace worn or damaged parts. Only use original Kemppi spare parts.

• Check the condition and connection of the welding circuit components: welding gun, earth return cable and clamp, sockets and connectors.

• Check the condition of the feed rolls, needle bearings and shafts. Clean and lubricate bearings and shafts with a small quantity of light machine oil if necessary. Assemble, adjust and test function.

• Check that the feed rolls are suitable for the ller wire you are using, and that their pressure adjustment is correct.

7.2 Periodic maintenance

NOTE! Periodic maintenance should only be carried out by a suitably qualied person. Disconnect

the plug of the machine from the mains socket and wait about 2 minutes (capacitor charge) before removing the cover plate.

Check at least every half year:

• Electric connectors of the machine – clean any oxidized parts and tighten loose connections.

NOTE! You must know the correct tension torques values before starting the reparation of the loose

joints.

Clean the inner parts of the machine from dust and dirt e.g. with a soft brush and vacuum cleaner. Also clean the ventilation net behind the front grill.

Do not use compressed air, there is a risk that the dirt will compact even more tightly into gaps of cooling proles.

Do not use pressure washing devices. Only an authorized trained electrician should carry out repairs to Kemppi machines.

7.3 Service Workshop maintenance

Kemppi Service Workshops complete maintenance according to their Kemppi service agreement.

The major points in the maintenance procedure are listed as follows:

• Cleaning of the machine

• Checking and maintenance of the welding tools

• Checking of connectors, switches and potentiometers

• Checking of electric connections

• Checking of mains cable and plug

• Damaged parts or parts in bad condition are replaced by new ones

• Maintenance testing.

• Operation and performance values of the machine are checked, and when necessary

adjusted by means of software and test equipment.

Software loading

Kemppi Service Workshops can also test and load rmware and welding software.

8. DISPOSAL OF THE MACHINE

Do not dispose of electrical equipment with normal waste! In observance of European Directive 2002/96/EC on waste electrical and electronic

equipment, and its implementation in accordance with national law, electrical equipment that has reached the end of its life must be collected separately and taken to an appropriate environmentally responsible recycling facility.
