ASSEMBLY OF SUPERSNAKE GT02S AND GT02SW

Before connection

Uncoil SuperSnake taking the feed mechanism body towards the intended welding area, and away from the welding machine. Ensure there are no tight bends before you load the filler wire.
Ensure that the correct filler wire support liner is fitted and installed correctly for the intended welding application. Kemppi manufacturer a range of support liners for different filler material types, including Steel wound and DL Chili. Please read the guide notes on liner selection and installation before use.

SuperSnake wire feed mechanism
Before loading the filler wire to SuperSnake please set the wire feed mechanism. Ensure the grooved drive rolls suit the filler wire size and type. Close and adjust the pressure arm.

Mounting and locking of wire spool

Ensure quality filler wire is loaded to the wire feed cabinet. Check that the correct wire guide tube and wire drive rolls are selected and fitted for the filler wire type used.

NOTE! Check that the filler wire spool is correctly mounted and locked into position. Ensure the spool is not damaged or deformed in such a way that it can rub or chaff against the internal surface of the wire feed unit chassis or door. This may result in increased drag, impacting on weld quality. This may also result in long term wire feed unit damage, rendering the unit unserviceable or unsafe to use.

Loading the filler wire and automatic feed

Automatic wire feed makes wire spool changes faster. When changing the wire spool, the pressure of feed rolls need not be released. Simply ensure that the groove of the feed roll matches the diameter of filler wire used. Release the wire end from the spool and cut off any deformed section. Be careful the wire does not spill from the spool sides. Straighten about 20 cm of filler and present the filler wire tip to the back of the wire feed rolls and press the wire inch button on the wire feed panel.
Now take a fine file or abrasive cloth and remove any sharp edges from the filler wire end, before loading to SuperSnake. This prevents damage to plastic liners in particular, and also prevents pick-up and stubbing inside metal liners when loading.

NOTE! Smaller diameter filler wires may need to be loaded manually – with the feed roll pressure arms released. This is because it is easy to over estimate the pressure required to feed these smaller filler wires. Too high feed roll pressures can easily deform filler wires and contribute to later feeding problems.

Adjustment of MXF/MXP pressure arms

Adjust the drive pressure to the filler wire with the thumb screws mounted over the pressure arms. Notice the graduated scales indicating load. The load applied should be sufficient to overcome a light braking force applied by hand to the filler wire, as it exits the welding gun contact tip.
For smaller diameter and soft filler wires, less feed pressure is required. It should be possible to apply a light breaking force to the filler wire by hand, as it exits the gun contact tip. But slightly more wire flow restriction should render the drives rolls to slip slightly over the filler wire without deforming the wire
NOTE! Excessive pressure causes flattening of the filler wire and damage to coated or cored filler wires. It also causes undue wear of the feed rolls and increases gearbox load, so reducing service life.

Adjustment of spool brake

Brake force is adjusted through the hole behind the locking clip. Remove the locking clip by hand, and adjust the tension and pressure to the friction pads mounted inside with a screw driver. See diagram and location A.

The load applied varies depending on the size and weight of the filler wire and spool, but also the filler wire feed speed set. The heavier the wire wire spool and the faster the feed speed, the greater the need to increase the braking load. Adjust the pressure, secure the locking clip, set the wire feed speed and check that the braking force is enough to ensure the filler wire does not spill from the spool on overrun.
NOTE! Too much or unnecessary loads can impact welding quality, load and wear to the wire feed system.

Communication cables
Support the SuperSnake coupling and guide the filler wire into the SuperSnake liner.
Then carefully mate and connect SuperSnake to the wire feed unit connector. Secure the SuperSnake by hand tightening the orange collar. The SuperSnake coupling transfers welding power, shielding gas and gun trigger lines. In addition you must connect both cable plugs
to the FastMig or ProMig wire feed unit sockets (from MXF synchronisation kit W004030 or ProMig ProSync 50 kit 6263121). This ensures wire feed motor synchronization, metering and remote control functions. Align and connect the plugs to the sockets and lightly tighten by hand. In ProSync applications, welding values are not shown. Instead, the display shows only dashes – – – .

Automatic wire feed to intermediate cable and gun

You are now ready to ‘Auto Load’ the filler wire. Ensure the FastMig or ProMig wire feed mechanism pressure arms are in place and correctly adjusted. Press the WIRE INCH button on the wire feed panel. MXF/PF system will automatically load the filler wire to the SuperSnake feed mechanism, and through the gun connector block. There should be a small amount of filler wire sticking out ready for gun connection.

NOTE! In ProMig applications, the automatic Wire Inch function is not available. You must press and hold the Wire Inch button or welding gun trigger, until the filler wire reaches SuperSnake.

Connecting the welding gun
Prepare your welding gun for connection. SuperSnake is designed to accept a wide variety of welding guns fitted with the standard Euro fitting. To ensure reliable welding performance, please ensure the gun is suitable for the intended welding application and is in good working order, correctly fitted with a suitable liner and contact tip.

Tread the filler wire into the welding gun and connect to the SuperSnake. Hand tighten the gun collar.
NOTE! Kemppi manufacture a range of quality welding guns, low friction loss gun liners and gun consumables, designed to compliment our welding products. Please consider these products before selecting an alternative.

Welding power controls
Ensure Remote control function is selected on the wire feed unit. SuperSnake provides
wire feed speed and voltage control in Basic MIG/MAG mode, plus Power and Arc length in 1-MIG and Pulse MIG. Note that Pulse MIG is not available in ProMig applications. Convenient welding parameter adjustments can be made during welding, allowing easy fine tuning of the welding arc.

Meter display (not available in ProMig applications)
The meter display provides essential welding data indicators. Depending on the MIG/MAG process selected, Voltage, Amperage, Wire feed speed, Plate thickness and Polarity will be indicated. Power and arc length adjustment can be made, prior to, and during welding via the potentiometers housed under the SuperSnake cabinet door. Post weld data is retained in the display for approximately 30 seconds after welding stops, providing that no additional control signals are received during this time.

Water cooled models
Water cooled SuperSnake models allow connection to the cooling fluid supply for liquid cooled guns. Snap connectors fitted at either end of SuperSnake unit are marked RED and BLUE, allowing simple, fast and convenient connection. Ensure the cooling fluid circuit is correctly connected.

Setting the shielding gas
The shielding gas flow rate from the welding gun is set according to the application, weld joint, gas type and gas nozzle shape and size. The flow rate should be measured at the welding gun nozzle before welding via a Rotameter, and normally measure’s between 10 – 20 litres per minute for many welding applications.

NOTE! Handle shielding gas bottle with care. Assess the risks associated with handling and using compressed gas. Always use a cylinder transport carriage and secure the cylinder safely.

MAINTENANCE

When considering and planning routine maintenance, please consider the 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.

Daily maintenance

• Check the overall condition of SuperSnake and 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.
