Artech TW163V auto/variable TUA

To weld a wire to a steel body, the magnet is used to make a return contact. Strip back thermocouple wire and grip this wire using the pliers approximately 25mm from the cut end. The charge button is pushed then released. After a short interval the LEDS change from charging to ready. Hold the thermocouple wire firmly against the steel surface and push the weld button.

This welds the wire to the steel body (auto mode: weld is made automatically 1.5 seconds after contact). The energy setting knob is used to set the required energy for different wire diameters.
