Can you please explain to me what the difference between say a 1.7 arc length compared to a -1.7 arc length and what the arc control does because the Miller rep couldn't explain it and just told us use 0.0 arc length and 200 wire speed and never said anything about arc control

I have been using these machines for a few weeks now. I am already putting in perfect roots every pass but I have a question. What does the arc length do exactly if you go in the plus' or minus' I usually leave it at zero and I get roots in the 5G with 2 mm reinforcement but it would be nice to know what that dial actually does. I cant find any kind of write up on it.

Hello Stephen! Thank you for reaching out. According to section 6 of the operation manual, the arc length is the distance from end of wire electrode to the workpiece. This term is also used to represent arc length adjustments in RMD and Pulse processes. Increasing Arc Length increases the actual arc length; likewise, decreasing Arc Length shortens actual arc length. We recommend leaving it at 0 as there usually is no reason to change it. Let us know if you have any additional questions.

To my understanding the arc length is a function of the voltage and wirefeed speed. A longer arc length has a greater voltage for a given WFS, and typically will produce a weld with less spatter, greater heat input, and more penetration, greater chance for burn through or dripping. In my application we had to limit arclength to avoid overheating the parts and causing excessive stresses in the parts.

jaime coronado The following settings are where we typically start our customers with: Wire Feed Speed: 200, Arc Length: 0.0, Arc Control: 0, Gas: 90/10 Ar/C02. Use these settings as a starting point and go up or down to fit your comfort zone. Please let us know if you have any further questions.

@@MillerWelders Hi, we are in offshore pipeline progress by using RMD/Pulse with Gas 80%Ar - 20% Co2. currently we are using the parameter WFS : 200, Arch Length : 0.6, Arc Control : 0. mostly defect on top location i.e 10 o'clock up to 2 o'clock position with defect Lack of root Fusion ore Lack of fusion by NDT exam PAUT. Can you please advise, does parameter that we are using is correct or no? some on 5 - 6 o'clock position always convexity instead of flat position.

This video was developed to illustrate a weld and the specific welding techniques and weld settings used are not necessarily the best for all applications. The Specification Sheet from the manufacturer of the filler metal you use is the best tool to determine starting welding parameters. We intentionally left the weld settings out of this video because following any local, state, or national codes or standards is the responsibility of the welding organization producing the weldment. Testing the weldment will ensure that the settings, technique, and overall procedure that you develop will meet the requirements of any applicable codes or standards. If you have any further questions, please let us know.

Can you do a tig root pass
@MillerWelders
@MillerWelders 5 жыл бұрын
Thanks for reaching out. The RMD process featured in this video is a MIG-only process. In general, you can use TIG for a root pass.

Why do you have to hold the trigger for a second or 2 to get it to feed? Is there an adjustment for that? I can’t find anything on it. It’s the only drawback to the machine I can think of. We have 2 at work and they both do it and nobody knows how to avoid or change it.

Probly for the shielding gas to start flowing before the arc is initiated. Just my best guess

its a preflow setting, if you hold the purge button and spin the trim knob at the same time it will let you enter a menu adn adjust the pre and post flow purge times.

This type of welding is pretty cool however don't believe the hype yes tig welding can seem impossible at first just like rooting with mig rmd its preference (what looks cheaper on a bid ) mig right? I disagree with this method it could cost more in the long run. it's not as easy as it looks however it comes naturel to me.......have fun that's all that matters....5% skill 95% confidence just wanted like shooting pool....

What carbon wire and gas is recommended for RMD
@MillerWelders
@MillerWelders Жыл бұрын
Great question, Chris! We would recommend using only a stainless steel wire with a high silicon content, such as a 316LSi or 308LSi . Higher silicon content helps the puddle wet out and acts as a deoxidizer. For optimum performance, use a “Tri-H” gas that’s 90 percent helium, 7.5 percent argon and 2.5 percent CO2. Alternatively, use 98 percent argon and 2 percent CO2. We also recommend taking a look at this article as it further discusses RMD: www.millerwelds.com/resources/article-library/new-regulated-metal-deposition-rmd-mig-welding-process-improves-stainless-steel-pipe-fabrication. Please let us know if you have any additional questions and we can happily assist. Thank you!

@@MillerWelders Thanks for getting back to me. This is one of the reasons I have stuck with Miller. I am 62 and the companies that I have worked for in the past would have issues Miller would send reps to the company to help fix the problems. Thanks for not throwing your customers under the bus so to speak.
