Experience the Freedom of Auto-Line™
Auto-Line™
Power Management Technology puts
you in control of the primary power.
Now,
primary power management begins at the plug and ends in your wallet.
- Better Weld
Quality, Uninterrupted Production
Rock steady arc even during fluctuations in primary power.
|
|
The
Auto-Line circuit boosts primary power to a higher, constant voltage.
Even if incoming voltage varies widely, the circuit ensures a rock-steady
welding or cutting arc.
|
- Universal Location
Flexibility
Permits direct connection to almost any type of input power—115-575
VAC (varies by product), 1- or 3-phase, 50 or 60 Hz.
|
|
- Draws Fewer
Amps
Permits more welding machines
without boosting incoming service.
|
|
- Exceptional Electrical
Efficiency
Helps your welding machine pay for itself through lower utility
bills and potential for rebates.
|
|
- More Welding
Output on 115V Primary
You get the max output for a given primary current draw.
As a result, machines like the Maxstar 150 can produce 30% more
welding power than competitive welders on 115 V primary.

Auto-Line
Technology Q & A:
| Q: |
What is dirty power? |
| A: |
Fabricators, contractors and manufacturers often fight weld quality
and maintenance problems that result from primary voltage fluctuations,
or "dirty power." Dirty power is the result of unreliable
primary power - large motors starting on the same primary power line,
utility brownouts or spikes, and generators that do not regulate auxiliary
power voltage. |
| Q: |
How does dirty power affect weld quality? |
| A: |
A power surge or dip can cause your arc to flicker and your inverters
to shut down for self protection. In some cases, you might not even
know you experienced dirty power until the QA/QC department rejects
your weld because it doesn't pass inspection. |
| Q: |
What can I do to protect my work from dirty
power? |
| A: |
Miller has developed its exclusive technology that frees operators
from primary power limitations and allows uninterrupted production.
Auto-Line is featured in Miller's Axcess Series of multi-MIG inverters;
TIG inverters such as the Maxstar 150 and 200 Series and Dynasty 200;
multi-process inverters such as the new XMT 350 CC/CV; and plasma
cutters such as the Spectrum 2050. |
| Q: |
How does Auto-Line work? |
| A: |
Auto-Line technology uses what's known as "boost converter."
This circuit boosts primary input power - from 190 through 630V or
anywhere in between - to a higher voltage. This voltage then charges
a capacitor, which is a device used to store and quickly discharge
energy. Power for the actual inverter section of the welder comes from
this capacitor. The inverter, therefore, has sufficient power as long
as the primary power remains within a +37/-59 percent of the nominal
460V power. In short, it's like drawing water from a well that's always
full. |
| Q: |
What does Auto-Line do for weld quality? |
| A: |
Auto-Line ensures that you always draw welding or cutting power
from a regulated, stable voltage source within the machine, which
lets you ride effortlessly through dirty power. Auto-Line gives you
a rock-steady arc, "on spec" welding parameters and equipment
with an incredibly dynamic, link-free operating range. |
| Q: |
What is the difference between Auto-Line
and Auto-Link®? |
| A: |
They're both examples of great technology from Miller. Auto-Line
automatically and continuously adjusts for voltage surges and drops,
providing a constant, steady arc and ensuring quality welds. Auto-Line
does this regardless of input voltage, provided it is within the
operating range of the equipment being used. Auto-Link "links"
power, switching transistors for either 230 or 460V primary power
only. |
| Q: |
How
do I know if an Auto-Line equipped inverter fits my needs? |
| A: |
Auto-Line is for anybody who can't afford re-work. And Auto-Line
also gives you the flexibility to use the same machine in the shop and
in the field because it smoothes out power fluctuations anywhere. |
