2.5.5 Cables

Kemppi always recommend the use of high quality copper cables with a suitable cross-

sectional 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 450 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 285 A 370 A 520 A 0.35 V / 100 A

70 mm² 355 A 460 A 650 A 0.25 V / 100 A

95 mm² 430 A 560 A 790 A 0.18 V / 100 A

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 450 power sources are designed to be used with MXF and MXP wire feed units.
