VIBRATING WIRE SPOT WELDABLE STRAIN GAUGE
Place a piece of shim strip on the prepared surface and place the welding probe in its centre. Apply gentle
but firm pressure. The welder will operate when it is triggered achieving one spot weld. Pull the strip off.
If the strip tears off leaving a hole in it, the weld is satisfactory, otherwise increase the energy level and
repeat test. Once energy setting is correct, weld the strip using three or four spot welds in a line and do a
pull test. Switch off the welder and disconnect earth connection.

Loose and unclean earthing may result in poor quality welds.
Unclean and too pointed tips will cause their fusion to the shim metal.
If a spark is seen when making the weld, reduce the energy setting on the welder.
Keep the tip clean and slightly radiused by rubbing it on fine emery sheet.
