4-17. Synergic Pulsed MIG Welding Advanced Settings

To change all values list, unit must be MENU FULL. To set unit to MENU FULL, proceed as follows:

Press P2 to enter SET UP menu.

Select MENU FULL on D1 and D2 (see Section 4-10).

Wire Feed Speed Unit (only in MENU FULL)

Use E1 to change D1 to UNIT.

D2 value is default setting of mpm (meter per minute).

Use E2 to change D2 to desired setting, ei- ther IPM (inches per minute) or CUR (weld- ing current in amperes).

Setting Pre−Gas (only in MENU FULL)

Use E1 to change D1 to PREG.

D2 value is default setting of 0.0 s (range is 0.0 s to 10.0 s).

Use E2 to change D2 value.

Setting Post−Gas (only in MENU FULL)

Use E1 to change D1 to POSG.

D2 value is default setting of 0.1 s (range is 0.0 s to 10.0 s).

Use E2 to change D2 value.

Setting BurnBack

Use E1 to change D1 to BURN.

D2 value is default setting of Auto (range is

1% to 200%).

.Auto is a setting below 1% that pro- vides an automatic backback time.

Use E2 to change D2 value.

3 Level Trigger Mode

Use E1 to change D1 to 3LS1.

D2 value is default setting of 130% (range is 20% to 200%).

Use E2 to change D2 value.

Use E1 to change D1 to 3LS2.

D2 value is default setting of 80% (range is

20% to 200%).

Use E2 to change D2 value.

Use E1 to change D1 to 3LRT (only in MENU FULL).

D2 value is default setting of 0.5 s (range is

0.1s to 0.5 s).

Setting Cooler Status

.Be sure that cooler is turned on for wa- ter-cooled torch to prevent damage to torch components.

Use E1 to change D1 to W−UN.

D2 value is default setting of ON.

Use E2 to change D2 value to OFF, if appli- cable.

Setting Synergic Double Pulsed MIG Welding

Some metals weld better using the Synerg- ic Pulsed Welding process due to the unique pulsing of the welding arc. Heat generated in the workpiece is generally lower and the arc characteristics produce a better weld bead appearance especially on aluminum. The Synergic Double Pulsed MIG process allows control all parameters to produce high quality welds on aluminum.

.Incorrect settings in Synergic Double

Pulsed Welding process can result in a program with undesirable weld char- acteristics. Setup should only be used by operators familiar with various welding processes and parameters. In some cases, standard Synergic Pulsed MIG welding can produce bet- ter welds.

Use E1 to change D1 to DP.

D2 value is default setting of OFF.

Use E2 to change D2 value to ON. This set- ting will enable or disable Double Pulse in Synergic Pulsed MIG welding.

Use E1 to change D1 to DPFR.

D2 value is default setting of OFF. Use E2 to change D2 value.

The range of this setting is 0.1 H to 5.0 H. This setting allows changing double pulse frequency in hertz (cycles per second). A recommended frequency is approximately 1 hertz. OFF means double pulse is off.

Use E1 to change D1 to DPDC.

D2 value is default setting of 50%. Use E2 to change D2 value.

The range of this setting is 25% to 75%. This setting allows changing the time that the pulse is at high output. A lower setting will produce less heating at the welding puddle.

Use E1 to change D1 to DPOF.

D2 value is default setting of 1.0M. Use E2 to change D2 value.

The range of this setting is 0.2 M to 2.0 M. This setting allows changing the difference in high wire feed speed and low wire feed speed from the main wire feed speed set- ting. For example, if main wire feed speed is set at 5 M and DPOF setting in D2 is 1.0 M, the wire feed speed will change be- tween 4 m/min and 6 m/min. A recom- mended setting is 1.0 M or less.

Use E1 to change D1 to DPAR.

D2 value is default setting of 0.0 T. Use E2 to change D2 value.

The range of this setting is −5.0 T to 5.0 T. This setting allows changing the high end of trim in double pulse and the main setting for trim will be the low end. A higher DPAR setting will produce a longer and hotter arc and lower setting will produce a shorter and cooler arc.
