ARC PERFORMANCE

Micro-Start II™ Technology — More than just a starting aid.

Better control for starting, arc stability and crater fill.

NOW INCLUDES for AC ALUMINUM WELDING

Great Starting

Micro-Start II™ Technology minimizes high

frequency and ‘hot starts’ to deliver soft arc starts without arc wandering for AC and DC welding.

Stable, Focused Arc

Micro-Start II™ Technology aids arc stability

THROUGHOUT THE WELD CYCLE –

even at the lowest amperage!

Precise Crater Fill

Micro-Start II™ Technology

controlled ramp down helps precisely fill

the weld crater for quality results.

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

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 TIG

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.
