No matter what you use, be sure to have your ground as close as possible to the weld area...Mike

1) While a good practice when welding on anything anywhere, keep the work lead (also called the ground clamp) as close to the actual welding as possible. I have seen a few damaged bearings and transmissions from folks not thinking about total current path! Bearing and transmissiona are particulary vulnerable components as the current makes a small arc across the metal surface as it travels from one piece of metal to another. This often leads to premature failure.
2) If using GTAW (AKA TIG or Heliarc welding), most systems initate the arc with superimposed high frequency. This is particularly damaging to electronic components. If you need to use GTAW, use the "scratch start" method, or the "lift arc" method if your machine is so equiped.
