Lessons Learned – Hazards of Arc Welding Near Electronics (~1985)
Year: 2002
Abstract: Abstract:
Starting voltages in excess of 400 volts during orbital arc welding may propagate at significant levels across interfaces into electronics. Some electronic devices may be sensitive to stray voltage levels as low as a fraction of a volt.
Use the referenced damage mitigation procedures, use a weld head that features a "touch start" feature, and avoid welding near electronic circuits.
