It separates display settings from observed events, explains what a supplier demonstration should record and provides a simple gas-use calculation. Final settings and acceptance remain governed by the specific equipment instructions, approved welding procedure and responsible welding engineer. The examples are planning aids, not tested GWELD parameters or universal welding prescriptions.<\/p>","protected":false},"excerpt":{"rendered":"<p>TIG pre flow and post flow control when shielding gas reaches the work before an arc starts and how long it continues after the arc ends.
