4-4. Crater Time Controls

2

1 Crater Time Control

Use control to reduce current over a set period of time (0–15 seconds) at the end of the weld cycle when NOT using a remote current control.

2 Crater Time Switch

ON – provides crater time.

OFF – provides no crater time.

Place switch in the OFF position for Shielded Metal Arc Welding (SMAW).

Application:

Crater Time should be used while GTAW welding materials that are crack sensitive, and/or the operator wants to eliminate the crater at the end of the weld.

Note: This applies if the operator is using an on/off only type control to start and stop the welding process.

4-5. Spot Time Controls

1 Spot Time Switch

Place switch in the ON position to turn on spot weld circuitry.

The (GTAW) TIG Spot process is generally used with a direct current electrode negative (DCEN) set-up.

Place switch in the OFF position to turn off spot weld circuitry. Put switch in the OFF position while do- ing Shielded Metal Arc Welding (SMAW).

2 Spot Time Control

Use control to set time (0–5.7 sec- onds) for Gas Tungsten Arc (GTAW) spot welds. Spot time be- gins at arc initiation. If the arc is bro- ken during the spot time cycle, the timer stops but does not reset. When the spot time has ended, weld output stops. Postflow starts when the remote contactor is opened. The spot timer resets after the contactor opens.

Application:

TIG spot welding is used for joining thinner materials that are in close contact, with the fusion method. A good example would be joining coil ends.
