Featured Welding Processes

Accu-Pulse

STANDARD on all Axcess

E models

The Accu-Pulse process allows for precise

control of the pulse arc. Accu-Pulse provides

optimum molten puddle control and has power

to increase wire feed speeds and deposition

20 to 25 percent in many applications.

In most cases, slightly different ratios of gas

mixtures will perform well using a similar

program and adjusting arc length or the

appropriate arc control for the selected process.

Contact Miller for more information on less

common materials and gas combinations.

Benefits

(Compared to conventional pulse)

Shorter arc lengths possible

Better puddle control

More tolerant of contact tip to work variation

Less audible noise

No arc wandering in tight corners

Narrow arc plasma column

Allows weld to fill in at toes increasing travel

speed and deposition

More tolerant of poor fit up and gaps

(compared to standard pulse)

Ideal for robot seam tracking applications

Accu-Curve

™

STANDARD on all Axcess

E models

Accu-Curve is a variation of the Accu-Pulse process. The transitions from peaks to background

voltage are “curved”. The curved transitions provide a “softer” feel without sacrificing the tight arc

lengths that allow for better puddle control and have become the hallmark of the Accu-Pulse process.

Benefits

“Softer” arc feel than Accu-Pulse

Maintains tight arc lengths

Maintains better puddle control

RMD

(Regulated Metal Deposition)

STANDARD on all Axcess

E models

The RMD process is a precisely controlled

short-circuit transfer. It is a method of detecting

when the short is going to clear and then rapidly

reacting to this data changing the current levels.

Features proactive dynamic puddle control.

Benefits

Well suited to thin materials

Can replace TIG process in some applications

Gap filling

Spatter reduction

Provides less heat into work piece

Excellent performance on stainless steel

Can be combined with other Axcess

-related

programs

Minimize distortion

Use larger diameter wire on thin materials

Note: To achieve optimum performance, 4/0 welding power secondary cable is recommended and the supplied work-sense lead must be connected as close to arc as possible.

Multi-MIG

Process Capability (Through software-based programs.)

Access the ideal welding process for any weld joint at hand. Whether you

need high travel speed combined with high deposition rates or require

gaps to be filled, any combination of the available welding processes can

accessed either at the start of a welding sequence or anywhere in the weld

while actually welding by using trigger or remote program select.

For a given wire-feed speed, the chart below shows from left (hottest) to

right (coolest) all the possible arc mode transfer ranges of accessible MIG

and pulse processes. This shows compatible shielding gas combinations

such as 90 Ar/10 CO

(90 percent argon and 10 percent carbon dioxide)

on steel using the same wire-feed speed and also gives an indication of

puddle control characteristics based on arc type selected.
