摘要：
Apparatus and a process for manufacturing mineral-insulated cable (10) has seam-welding heads for welding a travelling strip simultaneously at two or more spaced points (F1, F2, F3) to form a tubular sheath for the cable.
In another aspect of the invention, in start-up or shut-down of a process for manufacturing mineral-insulated cable wherein a strip is seam-welded to form a tubular sheath for the cable (10), the same quality of seam-weld (100) is ensured as for the steady state condition by controlling the arc current and voltage as a function of the speed of conveyance of the strip.
