In this second of two experiments conducted to investigate some possible causes of stress experienced by semi-automatic arc welders, the effect of the weight of the stylus and the length of the time which it was held were examined in relation to the tremor which resulted. A specially designed stylus was used to track along a straight line which was defined by two parallel pencil lines. Eight subjects performed this test and each tracked for various lengths of time with styli of two different weights. The results indicated a considerable increase in errors due to the weight and time, the weight appearing as probably the most significant factor. The relevance of these results is briefly discussed.
