Packaging

Tic Tac's CO2 fas and sub-merged arc welding wires are produced with raw material of teh highest quality,  copper-coated  and  precision wound on 15kg metal  spools . The spools are  shrink-wrapped  to  prevent   any  atmospheric  and   packaged   in   heavy-duty  carton boxes.  Plastic  adaptors  are  provided  separately.

 

Preparation of welding surface

  • Preparation of welding surface is of fundamental important in hte quality of hte joints obtained
  • The joints must be carefully degreased by mechanical brushing, removing in this way the oxidation or corrosion.
  • The use of gloves is absolutely necessary for handling the joints. Welding must be carried out immediately after brushing the joints.
