WIRE WELDING-CV

Connect a wire feeder to the VANTAGE® 575 CUM- MINS according to the instructions in INSTALLATION INSTRUCTIONS Section.

The VANTAGE® 575 CUMMINS in the ”CV-WIRE” position, permits it to be used with a broad range of flux cored wire (Innershield and Outershield) elec- trodes and solid wires for MIG welding (gas metal arc welding). Welding can be finely tuned using the “ARC CONTROL”. Turning the ARC CONTROL clockwise from -10(soft) to +10(crisp) changes the arc from soft and washed-in to crisp and narrow. It acts as an inductance/pinch control.

The proper setting depends on the procedure and operator preference. Start with the knob set at 0.

For any electrodes, including the above recommenda- tions, the procedures should be kept within the rating of the machine. For additional electrode information, See www.lincolnelectric.com or the appropriate Lincoln publication.

ARC GOUGING

For optimal performance when arc gouging, set the VANTAGE® 575 CUMMINS “WELD MODE” switch to the “CC - STICK” position, and the “ARC CONTROL” to 10.

Set the “OUTPUT” knob to adjust output current to the desired level for the gouging electrode being used according to the ratings in the following Table B.2

(1)When used with argon gas. The current ranges shown must be reduced when using argon/helium or pure helium shielding gases.

(2)Tungsten electrodes are classified as follows by the American Welding Society (AWS):

Pure

EWP

1% Thoriated

EWTh-1

2% Thoriated

EWTh-2

Though not yet recognized by the AWS, Ceriated Tungsten is now widely accepted as a substitute for 2% Thoriated Tungsten in AC and DC applica- tions.

(3)DCEP is not commonly used in these sizes.

(4)TIG torch nozzle “sizes” are in multiples of 1/16ths of an inch:

# 4 =

1/4 in.

6 mm

# 5 =

5/16 in.

8 mm

# 6 =

3/8 in.

10 mm

# 7 =

7/16 in.

11 mm

# 8 =

1/2 in.

12.5 mm

#10 =

5/8 in.

16 mm

(5)TIG torch nozzles are typically made from alumina ceramic. Special applications may require lava nozzles, which are less prone to breakage, but can- not withstand high temperatures and high duty cycles.
