I run a lot of 3/32. 1/8 and 5/32 Lincoln 5P+ Welding Rod I have a box or 2 of 3/16 Rod I have run for a short time. How safe is it to run that size Rod on my machine and how long can I run at a time. Thanks for your help John Sent from my XT1254 using Tapatalk
Reply:Looking at the numbers, 3/16" rod requires 150-225A.The SA200 is rated for 60% duty cycle at 200A.If one were to figure running the 3/16" at the 200A duty cycle you'd be able to "safely" weld continuously for 6 minutes out of every 10 or at its 60% duty cycle.MM200 w/Spoolmatic 1Syncrowave 180SDBobcat 225G Plus - LP/NGMUTT Suitcase WirefeederWC-1S/Spoolmatic 1HF-251D-1PakMaster 100XL '68 Red Face Code #6633 projectStar Jet 21-110Save Second Base!
Reply:Thanks again Duane so if I understand I could run it safely at 150 to 160 amps safely? JohnSent from my XT1254 using Tapatalk
Reply:You could safely run at 200A if you stay within the 60% duty cycle of welding 6 minutes out of 10.I've never see an actual duty cycle graph for the SA200 but only the 60% @ 200A. Based on that, operating at 150A is likely approaching if not at 100%. I would think 150A is at least at the 80% mark.MM200 w/Spoolmatic 1Syncrowave 180SDBobcat 225G Plus - LP/NGMUTT Suitcase WirefeederWC-1S/Spoolmatic 1HF-251D-1PakMaster 100XL '68 Red Face Code #6633 projectStar Jet 21-110Save Second Base!

Reply:Got a Pipeliner 200D.....( same as a Sa-200) ......I've run 1/4" Lo-Hy all day and never had a "duty cycle" or any other problem ...... Think your a little short of the runway with your amperage .......3/16" Lo-Hy runs 200-220 amps on my mocheen......even on xx10 rods I think your a little cold.... Sa-200's were made to run these rods ALL DAY......7/12's no problemLast edited by SmoothOperator; 08-28-2015 at 06:43 PM.
Reply:I have run some not that many at a time. But just wondered if it hurt the machine. Sent from my XT1254 using Tapatalk
Reply:I just have to ask, why do you guys run such big rod, and not a wire feeder? Dont pay any attention to meIm just a hobbyist!CarlDynasty 300V350-Pro w/pulseSG Spool gun1937 IdealArc-300PowerArc 200ST3 SA-200sVantage 400
Reply:I don't have a wire need and don't want one. I have several lbs of 3/16 and thought I would wse them if I could. John Sent from my XT1254 using Tapatalk

Reply:SA-200s will burn more of those rods than you want to be around for. It's not uncommon to burn 30+ pounds of 3/16 or the newer 5.0mm rod a day on a firing line. I have heard of big low-hy burning up these machines and wouldn't be surprised, low hy draws the heat. Don't forget that these old machines have no safety shut downs on the welding side of things for duty cycle. They just weld
Reply:DD274 at 30+ pounds that would be pretty much continuous welding without duty cycle time just straight welding. Wright? John Sent from my XT1254 using Tapatalk
Reply:The thing to remember is with stick there is no such thing as 100% duty cycle. I don't know of a stick electrode long enough to allow one to weld non-stop for 10 minutes. As soon as the arc is broken, the "weld" clock stops and the "off" clock starts.Take into account the time in ten minutes of welding (on) it takes to change electrodes (off), change positions (off), prep for restart (off), etc. and I think you'd be surprised how many minutes out of 10 you're actually welding. I don't think it's coincidence that most stick machines are typically advertised/rated at 60% duty cycle.Wire feeders are a different animal and 100% duty cycle ratings are common there. Higher duty cycles are certainly attainable and need to be taken into account when using a wire feeder on a stick machine rated at 60%.MM200 w/Spoolmatic 1Syncrowave 180SDBobcat 225G Plus - LP/NGMUTT Suitcase WirefeederWC-1S/Spoolmatic 1HF-251D-1PakMaster 100XL '68 Red Face Code #6633 projectStar Jet 21-110Save Second Base!
Reply:OK I guess it would be pretty easy to get 4 minutes off out of every 10 when you figure Rod change cleaning weld with wire wheel and other things. Couldn't get it through my head. Though it had to be 4 minutes straight time. Thanks again John Sent from my XT1254 using Tapatalk

Reply:I myself wouldn't use a wire feeder on an SA-200...... Just not cut out for it.....I believe someone on this forum used one as an Ironworker with a few others and burned the Sa's up!!!!!!!! Went to Sa-250's and ran alright w/ heavier machine......Keep up the info Duane always helpful hearing from a guru. |
