Connect remote control, torch, and work clamp to receptacles as shown.

4 Cylinder

Chain or secure cylinder to running gear, wall, or other stationary support.

5 Cylinder Valve

Open valve slightly so gas flow blows dirt from valve. Close valve.

6Regulator/Flow Gauge Install so face is vertical.

7Flow Adjust

Typical flow rate is 20 cfh (cubic feet per hour) (9.4 L/min).

NOTE: After activating remote con- trol, 0.3 seconds of gas preflow will begin.

Application:

Preflow is used to purge the imme- diate weld area of atmosphere. Preflow also aids in consistent arc starting.

NOTE: When remote control is released, gas continues to flow for 18 seconds

Application:

Postflow is required to cool tung- sten and weld, and to prevent con- tamination of tungsten and weld. In- crease postflow time if tungsten or weld are dark in appearance. NOTE: Both preflow and postflow are preset and are not adjustable.

NOTE: When AC welding, the bal- ance control is preset at 60% elec- trode negative (EN), and 40% elec- trode positive (EP).
