Should I be replacing some of these internals on my TD Cutmaster 51 torch?

admin

It's seen some good use before I got to it, and today I fried the stand off portion dragging it through slag...The Ceramic outer portion looks like it has some wear but I'm guessing it can wear a lot more before I would have to do anything about it?  Here's the tip components spread out.  The internal cup seems to be ok, but what should I be looking for?  The tip/orifice I'm replacing since I had a bunch extra that came with it...The electrode has some wear but according to the chart, it seems to be ok still.  I'm only showing about 24 thou wear and the limit is 65thou.  I have one more electrode that has very minimal use and two more that are unused.  I'm guessing I can use the worn electrode until I get to the wear limit and expend the precious metal insert?Here's all the components I have....What's the difference between the two different cup configurations shown on the box?  The upper one shows the components I have.  It's showing the torch oriented vertically and using the standoff piece...What's with the lower configuration that shows the torch at an angle?  Also the end is different... is this a drag cup?  What exactly is a drag cup and how do you use it properly?Thanks all.T
Reply:Just found out the lower components are gouging parts.  The upper setup is the cutting set.
Reply:I have the same consumables on my machine torch, they are not that cheap, i used to change the electrode + cup when the machine refused to strike an arc, but you can change them if u need the extra precision. Also, if you touch the torch to the base metal your electrode will die about 2 times faster.--------------------------------------------------------------www.becmotors.nlyup, I quit welding.. joined welder anonymous
Reply:What about that inner cup? 9-8213? I don't see this thing getting a lot of wear but don't really know the wear limits either.How about the brass nozzles? 9-8107 I'm guessing they should be replaced if the orifice starts getting wallowed out? Again, I'm looking for wear limits to apply to it.The outer cup looks like it could take a lot of damage (even more than it has now?) before thinking of replacing it? 9-8218Last edited by thordehr; 12-15-2010 at 10:21 PM.
Reply:9-8213 is a isolator(difuser i belive) if it's melted something went wrong, i think one will last at least 3-5 electrodes9-8207 .. well the orifice will start to get bigger and bigger as you cut , this will make your cut also bigger, i only buy the smallest ones cause they all go big eventually , I can't say the exact maximum wear it can handle as you can kill one in 2'' or 30meters depending on the mat thickness, torch distance from mat, torch angle, Amps used etc...the outer cup seems ok and will take a lot more abuse.wear breathing protection and a shade 9--------------------------------------------------------------www.becmotors.nlyup, I quit welding.. joined welder anonymous
