Welding Types And Parameters - Dacia 1304 2004 Repair Manual

At the reparation of the welded body elements, three welding categories may be used:
protection gas welding (CO2), electric spot welding and filling materials welding
(autogenous).
At the autogenous welding, it is recommended that flame must be slightly inclined so
that arch can be seen and the flame extremity to be maintained at aprox. 5 mm from the
part to be welded.
