Gouging Rod(s)?

admin

I've only heard of gouging rod for years and also have never seen anyone use it. What would be the general areas to use them and some areas you would not use gouging. Are there different sizes: 1/8 3/32 5/16 Sent from my iPhone using Tapatalk
Reply:They work real slick for removing welds / metal. A plasma works well too. But sometimes you can't get a plasma where you can get a carbon arc rod. You need about 300-amps, and lots of air. And a lot of room, sparks can be thrown quite a distance. I've seen the leads jump 2-feet off the ground! http://victortechnologies.com/arcair...5Code=&W6Code=Last edited by CEP; 12-15-2013 at 07:47 AM.Don’t pay any attention to meI’m just a hobbyist!CarlDynasty 300V350-Pro w/pulseSG Spool gun1937 IdealArc-300PowerArc 200ST3 SA-200sVantage 400
Reply:back in the 70's there was a rod that was called dh-2 or dh-4 that was used a lot for gouging out welds and defects. required about 300 amps or so but didn't require anything else. melted and blew the molten metal away like an air-arc and left a surface that was almost as clean. i think it was a p&h electrode brand and was handy as hell. gotta believe some other manufacturer makes a similar product today as p&h has long gone swallowed up by chemetron and esab.

Reply:The video , CEP, is what I'm talking about. My welder, a Lincoln 225 230v cracker box, won't work. Now that I can't use my welder that way, isn't there a tip for cutting out welds? Something like scarfing. I can't remember. I may borrow a friends pipeline welder and try gouging. I have a couple of items to try it on. Thanks for your helpSent from my iPhone using Tapatalk
Reply:I used gouging rods made with flux before, those were usally sold by companys who sold the maintenance type rods. I have seen 1-8  5-32  and 3-16 rod before. These didn't take real high amps to run. As for carbons for gouging 5-32  3-16 1-4   up to 3-4 . You need a gouging torch with a lot of air to run these. They also make them in flat as well. They make a gouge about the size of the electrode.I use the 5-32x3-8 flat carbons a lot, kind of like a metal eraser,saves a lot of grinding. You also can gouge with oxy-fuel.Miller xmt304,  Miller S22 p12, Miier Maxstar SD, Miller 252 w 30A, Miller super32p12, Lincoln Ranger 9, Thermal Arc 181I with spoolgun, Hypertherm 10000 ,Smith torches.

Reply:you're going to need a large volume compressor and ear protection and maybe even a fire watch if you're using the air/arc process. it's loud and sends molten metal a considerable distance. with a little practice it's very useful. oh yeah, air UNDER the electrode always.i.u.o.e. # 15queens, ny and sunny fla
Reply:I love arc air gouging. In a pinch, you can use 6010 rod to pierce or cut. Crank up the amps and burn away.JasonLincoln Idealarc 250 stick/tigThermal Dynamics Cutmaster 52Miller Bobcat 250Torchmate CNC tableThermal Arc Hefty 2Ironworkers Local 720

Reply:I've actually used 6011 to cut with. There is a OA tip used for cutting out welds but I can't remember what it's called. Sent from my iPhone using Tapatalk
Reply:Carbon arc cutting is very hard on the welding power supply.  You really don't want to be using anything less than 300 amps and 100 % duty cycle.  Most shops will their largest power supply in order to have lots of reserve... More like 500 or even 1000 amp machines.  If it conducts electricity you can gouge it.  Most common use is for removing cutting edges on heavy equipment.  Cutting edges often have so much chromium that they will not cut with a torch, similar to stainless.  The solution is arc - air or plasma with a gouging tip.   The other common use is to back gouge a butt joint.  It creates a nice U shaped groove on the back side when you take out the back side of a weld joint in order to get full penetration.
Reply:Guys, thanks. I've learned more in these sessions than all of my research has done. It's fun to go out to the shop an try the things you give me. Love to learn and love to work, just retired. Again, thanksSent from my iPhone using Tapatalk
Reply:For direct rods Forney and Farmers Choice list them ,I may have seen them in Tractor Supply too . Carbon arc can be had down to 1/8 and AC too but small ones are hard to find . We gouge at my part time job with a 250 amp tombstone all the time with 1/4 rods.To pierce out stuff a exothermic torch Arcair Slice or Broco works wonders ,only need ox and a battery to start.
Reply:Originally Posted by papasmirfThere is a OA tip used for cutting out welds but I can't remember what it's called.
Reply:Originally Posted by DSWYou got it earlier. It's called a gouging tip. Usually a bent tip with a different hole pattern designed to wash welds off plate and so on.Another way not mentioned yet it to use an oxy lance or exothermic torch. Both use high pressure O2 to cut. The exothermic torch like a Brocco torch looks a lot like a standard twist type stick stinger, but with an O2 hose and trigger attached to it. The rods look like a bunch of 12 ga copper wires all stuffed inside a wrapped tube, much like an oversized stick electrode. You strike an arc to light up the magnesium in the electrode and hit the O2 to begin cutting. You only need like 12v from a car battery to begin the process, and as long as you feed it O2, the torch will cut. It will burn thru just about anything, steel, concrete, bronze, wood, you name it. It's often used to remove pins on heavy equipment by blowing a hole straight thru the length of the pin. I've seen it used to remove welds, but it's no where near as good as Carbon arc or a gouging tip on a torch.

Reply:What polarity is used for arc gouging?  I would think straight / electrode neg.

Reply:Seems like several folks are talking about several seperate processes. There are specific gouging rods that are not arcair, they simply gouge on their own. I have experimented with them and didn't care for them. The  Arcair process is great for removing lots of material, such as bucket shanks.  Plasma gouging is also very clean and controllable.  It removes far less than the Arcair system. I haven't used a torch for that application myself.
Reply:Hypertherm makes a gouging torch for their machines looks really goodand when I ever get the 65 I am going to get both the standard hand torch and the 15 degree gouging torch http://www.hypertherm.com/en/Product...wermax65.jsp#4Backed my CATMA over your CARMA oops clusmy me  What would SATAN do ??

Reply:Thank all of you for this great info. You have really helped. On using the gouging torch tip, do I just follow the base of the weld? Sent from my iPhone using Tapatalk
Reply:Scarfing tip.
Reply:I describe air arc like plasma cutting, with depth control. I absolutely love the process more and more, every time I use it. Here is a thread I did in which I used it.http://weldingweb.com/vbb/showthread.php...air&highlight="Where's Stick man????????" - 7A749"SHHHHHH!!

Reply:But electrons flow from most negative to most positive. Wouldnt it gouge better with straight polarity DCEN (work clamp positive). The electrons will bombard the work and aid the cut? Also, it will be less destructive to the torch Hafnium, Tungsten , copper or whatever the tip/stinger is made of? Wouldnt it? Also, if I was  using 6010 to CUT with, it would cut better with DCEN electron flow, wouldnt it?.  I think plasma torch's use electrode negative and work positive or straight polarity.  Im confused but maybee not.

Reply:Used to cut lip rings off of steel ladles by air arcing with 3/4" carbon rod using 1000 amp millers. Burned up lots of leather jackets and gloves cutting out all that metal. Great process for metal removal but dirty and very noisy. Hearing protection and a good respirator are a must or you will damage your hearing and you will be blowing dirt out of your nose for a week.

Reply:all I can say is if someone asks you to carbon-arc some baseplates off some heavy I-beam columns that were welded all around, run like hell. there is no good place to stand to complete that processbosses stuff:trailblazer 325maxstar 200my stuff:sa 200fronius transpocket 180100 amp Lincoln w/f97 f350 DITKevin

Reply:Originally Posted by ExpatWelderI like plasma gouging too but you STILL need to grind because plasma leaves a nitride deposit which will cause cracking just as bad as carbon.............air is 70 or so percent nitrogen.
