Reducing or eliminating the need to make these trips to the power source can save an hour or more per welding operator each day in shipbuilding op- erations. Larger shipyards often have more than 100 welding operators on a jobsite, so the productivity gains and resulting savings can be signi? cant – adding up to thousands of dollars in time savings each year and justifying the equipment investment in remote- control technology.
Choosing a remote-control solu- tion that does not require a control cable also eliminates the downtime and maintenance cost associated with control cords. This cost can be signi? - cant and is often not accounted for.
Reducing Jobsite Safety Risk
Slips, trips and falls are among the most common causes of jobsite in- juries. Falls were the leading cause of worker deaths in the construction in- dustry in 2015, according to the Oc- cupational Safety and Health Admin- 48 MN April 2017
