During a TIG welding process, the arc current and arc voltage were 50 A and 60 V, respectively, when in the welding speed was 150 mm/min. In another process, the TIG welding is carried out at a welding speed of 120 mm/min at the same arc voltage and heat input to the material so that weld quality remains the same. The welding current (in A) for this process is
