Welding Operation, Twist Mate Electrode | Lincoln Electric IM609-B

B-7	OPERATION	B-7

6.Trimmer Potentiometers - Allows the meters to be calibrated in the field.

7.Digital Ammeter - The ammeter displays actual welding current during a weld cycle and displays the peak current for approximately 5 seconds after welding is complete. Otherwise the machine’s set current is displayed. Read the complete Operating Instructions section for more information on the Ammeter.

8.Digital Voltmeter - This meter displays welding voltage, as measured on the output studs of the Square Wave TIG 275. After welding is complete, the meter displays the welding voltage correspond- ing to the peak welding current and displays this value for approximately 5 seconds

9.Thermal Protection Light - A yellow light which only lights when an over temperature situation occurs. See the Maintenance Section for more information on thermostatic protection.

10. Power Switch - Turns power “ON”

“OFF” to the welder. When switched “ON” the digital meters will illuminate, indicating that the power is on.

11. Polarity Switch - Selects DC+, + AC

or DC- - welding polarity without reconnecting leads. DO NOT SWITCH WHILE WELDING.

12. Twist Mate Electrode

and

13.Work Connections - Easy to connect elec- trode and work connections. This style Electrode Connection makes the gas and current connec- tions for the TIG torch at the same time. (Adapter plugs are provided with the machine.)

14.Remote Receptacle - For Amptrol, Arc Start Switch or Robotic Interface connection.

15.Optional Water Solenoid Connections -

Easy to install this optional feature which allows for water flow control for water cooled torches.

TIG WELDING GUIDELINES

TIG welding can be done in either the TIG 2-Step

or the TIG 4-Step Weld Mode. TIG 2-Step is typ- ically used with Hand or Foot Amptrols, with Remote Current control. TIG 4-Step typically uses an Arc Start switch and Local Current Control, because it provides a very brief current upslope, and a .5 to 10 second adjustable current downslope. TIG 4-Step also func- tions like a trigger interlock, making it unnecessary to hold down the Arc Start switch during a weld. If remote current control is desired in this mode, a device which provides separate arc start and current control must be used. Read the TIG Welding Sequence of Operation sections for more details on 2-Step and 4-Step opera- tion.

Recommended tungsten electrode sizes, stickouts, currents, cup or nozzle sizes are shown in Table B.1.
