Tried some welds on flat 1/2" plate

admin

Using a rod we get here from Arctec called 222

Reply:Looking at your pic, the numbers to the left are the amps with 1/8 inch rod. All the beads look much to cold for 1/2 inch plate. The beads are sitting on top and have not flowed outward. I suspect that the backside of the plate has little or no heat marks, shallow penetration.

Reply:Scotty, More power, more power!!!!!!!!Come try it out and stay a while.
Reply:Think 200+ amps.
Reply:Well I actually was doing it just to see how it would look, I normally would have used thinner plate to practise, and the machine only goes up to 180 Amp AC, and the rods don't go that high in that size they say on the package 100-140 Amps, so did not think I should crank it above that.so maybe I shouldn't play with heavy plate for practise and stay with lighter metal.
Reply:Hummm......180 amps on 1/2 inch plate, 140 amp max rods. You’re short. Running a bead on flat plat is very different to welding a joint, butt, T, gap, V grove.
Reply:140 amps should be more than enough amps for 1/8 7018 rod.  in my opinion, i think your travel speed is too low.  drag your rod a little faster, but not too fast that you leave undercutoops!! i didnt read the part about what rod you were usingLast edited by gto_welder01; 02-11-2010 at 12:22 PM.

Reply:This is the welder from around 73 or so.
Reply:What’s the A/B jacks all about?
Reply:Three recommendations...Call up Arctec and tell them what rod you are using and what machine you are using and what settings and ask them if it's capable, etc...If Arctec doesn't know anything about the machine, try the same thing with your local welding supply.If that doesn't work, get the voltage/amperage spec from Arcted for the rod running under AC and the connect a good (really good...has to be capable of reading voltage through the clamp of 12v or lower...alot of them only read 70v or higher) clamp multimeter over your lead and read of the voltage when running at max amperage and see what it is in comparison to the recommended.--Wintermute"No man's knowledge here can go beyond his experience." - John Lockewww.improvised-engineering.comManufacturer Agnostic:Blood----------Sweat---------Tears----|------------------|----------------|----Lincoln Red, Miller Blue, Esab Yellow

Reply:Ok, strictly an AC welder.
Reply:Originally Posted by partsmanHigh and low range A I think was the 90 to 180 and B was 0-85 or something like that.
Reply:Originally Posted by wintermuteAre you sure that was the order?  Were you actually running the amperage much lower than you thought because you plugged it into the low socket instead of the high?--Wintermute

Reply:Originally Posted by BruceTSActually it does.....if you look closely, you can see ABABABABABABA for each band.
Reply:Originally Posted by transitThat’s what I was leading to. But what selects the Blue, Brown, Orange, Green, Black and Yellow bands?
Reply:Originally Posted by BruceTSLook to the far right of the bands and it shows different types of materials listedNot knowing exactly what a 222 rod is I just comment on what I see generally. See all the spatter BB's around the 145 amp beads. Even though AC will spatter more than DC that shows that the arc is hotter than it needs to be. All beads look cold  but thats probably due to your movement speed and the thickness of the plate. Get you a stick of 1"X 3/16 or 1/4 flat bar. Cut it into 6" strips for practice strips. This can be beads or joints of any kind. Strike an arc and as soon as you got a puddle going start moving at a steady speed that keeps the arc at the front edge of the puddle. Try little or no weaving. If you're making circles make them very tight(1 1/2 rod width total size) or try a straight drag. Try this at 120 amps and see what you get.Tough as nails and damn near as smart
