Indications for replacement

1. Protection of bodywork.
   • Remove or cover the interior furnishings of the vehicle (upholstery, instruments, carpets).
   • Cover glass, Instruments, upholstery and carpets with heat resistant materials before attempting welding operations, particularly when arc welding is carried out in a CO₂ atmosphere.
2. Protection of external components.
   • When external components (bonnet, boot, mouldings, trimming) are removed they must be adequately protected from scratching by using rags, protective tape or other materials.
   • Painted surfaces which only show signs of scratching should also be repaired as even light scratches can lead to corrosion.

INDICATIONS FOR REPLACEMENT

The use of genuine Alfa Romeo spare parts is recommended. These ensure the best results with regard to repairs and maintenance of vehicle serviceability.

INDICATIONS FOR WELDING

Before electric welding, remove the electronic control units from the vehicle to avoid damaging them.

SPOT WELDING

Spot-welder.

The strength of spot-welds depends on the execution of the following checks before welding operations begin:

1. Adjustment of the welding arm.
   • Keep the arm as short as possible in order to maintain maximum loading between electrodes.
2. Alignment of electrodes.
   • Align the tips of the upper and lower electrodes. Any misalignment of the electrodes causes low pressure on welding points resulting in a reduction in strength.

1. Welding arm
2. Tip of electrode
3. Minimum arm length

1. Incorrect arm length
2. Incorrect position of arms
3. Correct alignment of arms
