4. Keep the torch in good repair and all connections tight to reduce high frequency leakage. 5. The work terminal must be connected to a ground within ten feet of the welder, using one of the follow- ing methods. a) A metal underground water pipe in direct con- tact with the earth for ten feet or more. -
Page 11: Arfu (Auto-Restore Fuse
Fuse the input circuit with time delay fuses marked “D” or delay type circuit breakers. Using fuses or circuit breakers smaller than recommended may result in “nuisance” shut-offs from welder inrush currents even if not welding at high currents. Also called inverse time thermal/magnetic breakers. -

Connector are supplied with the welder. To connect the cables, turn the Power Switch “OFF”. Connect the torch Twist Mate plug into the DC(-) Electrode/Gas Output Receptacle on the front of the welder and turn it clockwise until tight.

Obtain the necessary inert shielding gas. Connect the cylinder of gas with a pressure regulator and flow gage. Install a gas hose between the regulator and gas inlet (located on the rear of the welder). The gas inlet has a 5/16-18 right hand female thread; CGA #032. -
Page 14: Operation
Read and understand this entire section before operating your machine. SAFETY INSTRUCTIONS WARNING ELECTRIC SHOCK can kill. • Do not touch electrically live parts such as output terminals or internal wiring. • Insulate yourself from the work and ground. • Always wear dry insulating gloves. ------------------------------------------------------------ FUMES AND GASES can be dangerous. -

REAR CONTROL PANEL 1. Power Switch: Controls the input power to the machine. Make sure the machine is properly con- nected to the input supply before turning the machine on.(See Figure B.1) 2. Fan: The cooling fan will turn ON when the machine is turned ON and it will continue to run whenever the output of the machine is ON. - Page 16 When the mode switch is in the Lift TIG position, the stick welding functions are disabled and the machine is ready for Lift TIG welding. Lift TIG is a method of start- ing a TIG weld by first pressing the TIG torch electrode on the work piece in order to create a low current short circuit.
- Page 17 12. Postflow Control: In the TIG welding modes, this control knob will adjust the shielding gas postflow time from 0.5 to 30 seconds. (The preflow time is always 0.5 seconds.) In Stick welding mode, this function is not used. 13. Digital Display: This meter displays the preset weld- ing current before welding and the actual welding current during welding.

DIP Switch 4: 4 Step Restart Enable This controls the 4 Step Restart function. When the switch is ON the 4 Step Restart function is enabled. ("Foot pedal" remote controls should never be used with the 4 step sequences.) 4-Step Restart Disabled (DIP Switch 4 = OFF) 1. - Page 22 4-Step Restart Enabled (DIP Switch 4 = ON) Same as step 1. Same as step 2. 3. Press and hold the TIG torch trigger when the main part of the weld is complete. The machine will now decrease the output current at a controlled rate (downslope), until the Start/Crater current is reached.

Page 23: Dip Switch 5: Low Ocv Enable
b-10 DIP Switch 5: Low OCV Enable This controls the OCV of the machine. When the DIP switch is OFF the OCV is set to the normal level as stated in the manuals for the machines. When the DIP switch is ON the OCV is reduced to 20V. This low OCV mode was created for the Australian markets and should only be used as required by these Australian specifications. -
