WELDING

What Is It?

Pulse welding systems vary weld current between peak (high heat)

and background current (low heat) levels. Adjusting the pulse fre-

quency controls the level of heat input applied to the weld relative

to the weld travel speed.

Results

Better control of heat input in the weld, resulting in:

• Reduced warping and burnthrough on thin materials.

• Smaller heat-affected zone – good for thin material.

• Smaller bead profile without compromising proper penetration.

Great For

•Thin materials – Faster pulse settings help to narrow the bead

profile and minimize the heat-affected zone and resulting warping

or burnthrough.

•Consistent appearance – Slower pulse settings aid in timing the

application of filler metal to produce the consistent stacked bead

appearance associated with high quality TI

welding.

•Maintaining a steady welding rhythm.

Easy “Set It/See It” Operation:

• Flashing indicator light lets you see the

pulse rate before you strike an arc.

“Set It/See It” Pulse Control — Make attractive and consistent welds!

AC Auto Balance®Controls —

Auto atically sets the opti al cleaning vs. penetration

level for alu inu welding!

What Is It?

When aluminum welding, the positive (+) portion of the AC welding

amperage cleans the oxides from the aluminum surface. The neg-

ative (-) portion delivers more heat input, increasing penetration

level.

Patented AC Auto Balance®automatically sets the ratio of

cleaning action (+) versus penetration (-) based on amperage.

Manual balance control provides the flexibility to customize

the arc to your preference.

Easy Operation:

• Set it and forget it or override when you choose to customize

the settings.

PERFORMANCE

• Excellent stick welding performance.

— Weld steel, stainless and low allow metals with ease.

— Weld sheet metal, pipe and heavy plate.

— Weld with Lincoln®Blue Max®Stainless, Excalibur®Low

Hydrogen and Fleetweld®5P welding electrodes.

• Wider output range — for maximum flexibility:

— 2-420A DC, 2-420 AC.

• More amperage than nearest competitor at 40% duty cycle — 25

amps more!

• Lower input current draw compared to nearest competitor — up to

10% less current with 40% more duty cycle.

QUALITY AND RELIABILITY

• Fan-As-Needed™ (F.A.N.) minimizes repeated heating and cooling

of internal components, keeps dust and dirt build-up to a minimum

and saves on electricity costs.

• Engineered cooling air routing brings clean air in from the top and

exhausts at the bottom to draw and collect less dirt in the machine

(see photo at right), unlike competitive systems with a vacuum

cleaner-like floor intake.

• Compare these reliability enhancing design features:

— Crimped and soldered power connections.

— Wound and varnished electrical coils do not require coil spacers

to remain secure. Competitive models use wooden coil spacers

that can loosen over time.

— Locking tabs on PC board connectors eliminates loose

connections.

• Tough testing cycles ensure long service — dropping, jerking,

rolling, shipping, vibration, resistance to real world extreme

conditions, and extended in-service life testing.

• Line Voltage Compensation holds output setting constant to

maintain weld quality even when the input voltage fluctuates ±10%.

• CSA C/US certified.

• Lincoln three-year warranty on parts and labor. Two-year extended

warranty available in the U.S.
