When ITW appears on D1 and D2,

press P3 and P8 simultaneously.

 

 

When MEMO CLEAR appears on

 

D1 and D2, release P3 and P8.

 

Wait until DONE appears on D1,

 

and turn unit Off.

 

The next time unit is turned On, all

 

parameters will return factory de-

Press P3 until desired process LED illumi- nates.

Values and parameters that appear on D1 and D2 are either factory default settings or last settings entered for the selected pro- cess.

L1 selection is Manual MIG welding.

D1 value is welding voltage, default is

18.5V (range is 10.0V to 50.0V).

D2 value is wire feed speed, default is 5.0 m/min (range is 1 m/min to 20 m/min). See Section 4-11.

L2 selection is Synergic MIG welding (non-

pulsed).

D1 value is trim, default is 0.0 T (range is −5.0 T to 5.0 T).

D2 value is wire feed speed (from minimum to maximum value according to welding curve selection).

.When L2 is flashing, material transfer

in the arc is by large droplets (globular transfer) and produces considerable spatter. This is the result of selecting a specific material, wire, gas, voltage, and current combination. To avoid this situation, Synergic Pulsed MIG weld- ing with the same parameter combina- tion is recommended. When L2 is On continuously (not flashing), material transfer in the arc is either short circuit (Short Arc) or by small droplets (Spray Transfer). Both MIG processes pro- vide a stable arc and minimum spatter.

L3 selection is Synergic Pulsed MIG weld- ing.

D1 value is trim, default is 0.0 T (range is −5.0 T to 5.0 T).

D2 value is wire feed speed (from minimum to maximum value according to welding curve selection).

L4 selection is TIG welding or STICK weld- ing.

If selected process is TIG:

D1 displays TIG, and D2 value is welding current, default is 220 A (range is 10 A to 400 A).

If selected process is STICK:

D1 initially displays STICK and changes to open circuit voltage at approximately 85 V, and D2 value is welding current, default is 220 A (range is 10 A to 400 A).
