Putting machine in operation

Options

The unit (MIG 175 ZW/A, MIG 190 Kombi/A with two-phase 400 V/230 V and an adaptor) is factory-adjusted for one-phase current

supply, frequency 50/60 Hz, 230 V. The unit (MIG 175ZD/A, MIG 220ZD/A, MIG 250ZD/A, MIG 350ZD/A) is factory- adjusted for

two-phase current supply, frequency 50/60 Hz, 400 V.

Two following works should be done:

Plug assembly (except for MIG 175 ZW/A a MIG 190 Kombi/A)

Wheel assembly

Bottle assembly

Hose pack assembly

Wire coil fit

Plug assembly

MIG 175 ZD/A, MIG 220 ZD/A and MIG 250 ZD/A units should be connected to a CEE-16 A plug (not included) On MIG 350 ZD/A,

CEE- 32 A plug (not included) is recommended (to be fitted with a ground wire. That should be done by a skilled person.

Notice: A thermal fuse is provided on the machine to give the transformer overload protection and to switch the machine

off when it is overheated. After a time of cooling down, the machine is ready for use again.

Wheels mounting

The slide is provided to have two rotary front wheels fitted on it and to carry an axle for attaching two fixed rear wheel. . A tool bag

is delivered with contents as follows: rotary front wheel, fixed rear wheels axle, rear wheels, pins, cotter keys and a cage nut.

Screw the cage nut in respective devices, see Fig. 5 and 6. Fit in the front wheels according to Fig. 7. Insert the axle to fit the rear

wheels and fix it using the cotter keys.

Bottle assembly

Put the bottle vertically on the holder surface and let it to stand on the holder, then fix it with a chain and spring hooks as shown in

Fig. 8 Screw a pressure gauge on the bottle and put a grib tube (see Fig. 9) on the gauge and the electric valve using a clip.

Hose pack mounting

To connect the hose pack, it will be sufficient to firmly screw together the pack and EURO central connection on the front side (Fig.

10). In this way, you will effect the electrical connection and gas connection to the bottle

Wire coil fit

Put the wire coil on the hub and insert the wire in the drawing device, Fig. 11. Any model without exception will accommodate coils

of weight 5 kg and 15 kg. The hub ha a coupling fitted to provide for the correct tension of the wire.

Wire tensioning motor

Make sure that the wire feed pulley has a guidance groove corresponding to the wire diameter. The machines are equipped with a

wire winding of ∅ 0.6 and ∅ 0.8. The diameter is embossed on the side of the winding

Wire guidance

Cut the initial 10 cm of the wire off and make sure that the end is straight, free of any protrusions, deformations and impurities. The

wire tensioning device moving arm may be opened by loosing the screw on the arm, see Fig. 12. Insert the wire in respective

guidance groove and close the pressure arm again. Set the optimum resistance on hub 15 (the wire should be let pulled easily from

the winding, however, not unwinding by itself). Set the thrust using a screw on the pressure arm (Fig. 14).

Setting up 230/400 V (Model „MIG 190 Kombi/A“ only)

The welding machine may be operated with both 230 V and 400 V. Make sure that the voltage changing switch (230/400 V) position

complies with the selected plug.

Accident prevention regulations

Welding poses many risks to the operator and the viewers.

Personal precautions!

• Wear suitable clothing of pure cotton – shirts without any pockets and pants without turn-ups.

• Always wear insulating gloves.

• Wear heavy-duty insulating shod boots.

• To protect your eyes, wear protective mask and filter and clear glass goggles to be protected on sides. Caution, do not inhale

fumes from welding!

• Make sure that the working area is properly ventilated. If necessary, in poky spaces in particular, use a good extraction plant.

• Clean the parts to be welded of rust, fats and paints to prevent smoke from material during the welding job.

Where necessary, use a welding spray.

• Short circuit hazard! Check the mains for protection against overloading and short-circuiting and make sure that

suitable grounding facilities are provided. Make sure that the mains voltage corresponds to that, which the machine is

designed for.

• Make sure that there are no damaged or bare cables on the device. Where necessary, replace the mains cable, hose pack or

the welding cable.

• Make a good connection with the ground.

• Never put a cable from the hose pack or the ground around your body. Do not take the hoses to aim at yourself or other

people.

• Never get down to a welding job in wet or humid environment. .

• Never work on the machine without the side protection device.

• Explosion hazard! Never work in proximity of readily flammable materials or easily inflammable tanks.

• Place the machine on the floor in a way providing for a stable position of the machine.

• The gas bottle should be fixed to the machine using a suitable chain, at a safe distance from any sources of heat.

• Never expose the welding machine to weather condition and do not store it in wet places. Electronic structural

elements could be spoiled by a short circuit or corrosion.
