Auto-Set™ Advantages for the Professional

Tuesday, June 4th, 2013

The Auto-Set feature on many of the Millermatic® MIG welders makes setting up a MIG machine very easy for the novice welder, but can help the experienced welder, as well.  Most experienced welders have no problem grabbing a piece of scrap and laying a few practice beads to dial their MIG machine to the exact parameters that work in their application.  That may be necessary if you’re welding an intricate project, but if you’re not, it may be more valuable to save the time and scrap material and just use Auto-Set.  Simply use the dial to set your wire diameter and material thickness — parameters you already know.

Auto-SetThe Auto-Set feature gives you one knob to adjust to easily adjust to any thickness or joint configuration.  It detects what material thickness you have selected and adjust your parameters accordingly.  Auto-Set is very similar to the synergic MIG feature you see on some of the industrial equipment.   The convenience is being able to adjust parameters with a single knob.  You can think of the single knob as a heat knob that makes the weld hotter or colder.  Auto-Set offers the operator six to nine preset parameters that correlate to different material thicknesses the machine is capable of welding. For example, if you’re welding two pieces of 14 ga material and you feel the parameter is too cold, bump the material thickness knob up to 1/8” for a hotter parameter.

We often hear comments that a welder can optimize their parameters manually.  While that is possible, there are so many variables (input voltage, wire brand, welding technique, etc) that go into setting a parameter that  a perfect parameter takes time to achieve , and thus may not always make sense.

Here are some common applications where Auto-Set can make you more efficient:

  • Simple everyday repairs
  • Time sensitive repairs (ex. race repair)
  • Projects that involve multiple material thicknesses
  • Projects that require welding in multiple positions

Auto-Set can’t adapt to the preference of each operator, but it will give a very good starting parameter that is much faster and easier to set.  Next time you have a quick weld to make, give Auto-Set a try and save yourself some time and material.

What do you need to start welding Aluminum?

Friday, February 1st, 2013

If you already own a MIG welder, you may be wondering what it takes to start using that machine to weld some aluminum. Miller® has continued to provide spool gun solutions that are simple and directly connect to your welder for welding aluminum. This makes changing to aluminum faster and less expensive than you may think.

First, you’re going to need a spool gun. Why another gun? Well, the column strength or the amount you can push on Aluminum wire without buckling is only about one-third the amount that mild steel wire can withstand. This causes feeding issues if you try to push the aluminum through a standard MIG torch. Spool guns only push the wire a short distance in a straight line from the drive rolls, so feeding isn’t compromised. The Spoolmate™ 100 Series spool gun is a direct connect option for the Millermatic® 140 Auto-Set™, 180 Auto-Set and 211 Auto-Set with MVP MIG welders, and the Multimatic™ 200 MIG/TIG/Stick welder. The Spoolmate™ 200 Series spool gun is the entry level spool gun for the Millermatic 212 Auto-Set and Millermatic 252 MIG welders. For the more industrial user, the Spoolmatic® 15A or 30A guns are a better fit on those machines.

The next thing you’re going to need is different shielding gas. Aluminum requires 100 percent argon shielding gas. Any shielding gas containing oxygen will cause an unstable arc with impurities when welding Aluminum.

Finally, you will need to be sure you have good MIG welding technique.  Aluminum requires you to push the torch to ensure effective shielding gas coverage. Everything else in your technique is the same as welding mild steel, but at a faster pace. Due to the high thermal properties of Aluminum, more heat is required to start a molten puddle. This increased amount of heat then requires a higher travel speed once the puddle is established to prevent burn through. Aluminum MIG welding doesn’t have to be difficult with the appropriate equipment and some practice.

New Miller XR™-Pistol-Pro Gun Designed for Aluminum MIG and Pulsed MIG Welding
