I have a FL150 torch I was using yesterday and at 120 amps. I was welding a longer bead, I use half stick 3/32 steel tig rod. I was welding 11 gauge plate to .78 wall square tubing. When I finished with about half a dozen of the beads, I noticed the torch head had some heat damage. The torch head was turned to about a 45 degree angle from straight on. I would not have expected this, especially since I was wearing thin tig gloves and it wasnt burning my hand. Is this to be expected? I would replace the parts, but if its just going to burn up, I will use it until it dies then find a higher quality torch.

Reply:I can this evening. Its a blistering on the plastic parts of where the actual head locks and part of the torch neck.Regards,RobGreat Basin WeldingInstagramBlue weldersRed weldersMy luscious Table DIY TIG Torch cooler
Reply:Was the head tightened to the body. I have the water cooled version of this torch (the smaller one though), and it relies on tight contact between the two metal surfaces for heat to be conducted away from the head into the handle. Also, if this connection is at all loose (or oxidized), there will be heating across the gap due to the welding current. That could itself heat the torch from the inside, hotter than it would get from just normal use.
Reply:Yes, quite tight. But thank you for the heads up.Regards,RobGreat Basin WeldingInstagramBlue weldersRed weldersMy luscious Table DIY TIG Torch cooler
Reply:I run my ck fl150 at 180 amps with no problems...thats on the lincoln 250 250....it runs a little hotter than stated amperage according to the clamp meter. I did several 6in welds that way and the power cord was so hot it made my arm itch like a banchee from having it wrapped around my forearm. But the torch is fine..I do notice that the handle will easily loosen with the heat expansionMiller Syncrowave 210 w/CK FlexLoc 150 3/6/14ESAB PCM 1125 Plasma CutterAtlas 12x36 LatheACER 9x42 3hp millHarig 612 Surface GrinderDRINK Machine welding&fabrication

Reply:If I was smarter I probably should have stick welded it. Regards,RobGreat Basin WeldingInstagramBlue weldersRed weldersMy luscious Table DIY TIG Torch cooler
Reply:All on the side facing the tungsten. Almost looks like it was reflected heat that burned it from the outside in.By my smaller water cooled torch gets much closer to the heat, and I've had it up to 200a with no damage. Up to the point that I had to switch to stick welding gloves to avoid the reflected heat.Last edited by rlitman; 03-03-2014 at 11:59 PM.
Reply:And that's the thing. I'm using thin tig gloves. No burns yet. No more heat than 150 amps.Regards,RobGreat Basin WeldingInstagramBlue weldersRed weldersMy luscious Table DIY TIG Torch cooler
Reply:So according to CK these parts are "consumable".I call bull$#!T.Regards,RobGreat Basin WeldingInstagramBlue weldersRed weldersMy luscious Table DIY TIG Torch cooler
Reply:That looks like a pivoting head torch. I inherited 2 of those torches when i bought my machine used. They both have overheat damage at the pivot, and in other areas as well. I just couldn't get them to fly right. Too many orings and connections I suspect. I wonder about using them as a general use torch. Too complicated IMHO.I went to a fixed torch that has a sort of a flexible head (The third one included with the machine). It has served me MUCH better.I don't know if there is some design flaw with them; perhaps they need some kind of maintainence to continue to perform well.Chay
Reply:I have been using one for about 2 weeks now. 140amps, AC, 17 head. No issues at all. I love this torch.And yes the screw is a consumable. It has to be, if you forgot to tighten it you will arc out spots on it and your torch. If it wasn't they would be handing them out like candy.Torchmate 2x2 CNC with Flashcut CNC controlsHypertherm Powermax45 Esab ET220i Razorweld 195 MigRazorweld 200ac/dc TigTormach 770, Tormach xstechRazorweld, Vipercut/Vipermig, SSC Foot Pedal Dealer
Reply:I just got an email back from the VP there, and others.The flexloc material is phenolic and has a melting temp of 500F according to them.I don't think a material that melts at 1/5th the temp of what one welds 1 1/2 to 2" away is a great design. Maybe I'm missing something, but I'm also a little disappointed.Regards,RobGreat Basin WeldingInstagramBlue weldersRed weldersMy luscious Table DIY TIG Torch cooler
Reply:How about some reflective tape on there ?You are doing something wrong if you are getting that thing 500*. The Pyrex cup also has a melting point of 500* and if you use it correct it won't melt. That's a lot closer to the work piece than that part of the torch.Torchmate 2x2 CNC with Flashcut CNC controlsHypertherm Powermax45 Esab ET220i Razorweld 195 MigRazorweld 200ac/dc TigTormach 770, Tormach xstechRazorweld, Vipercut/Vipermig, SSC Foot Pedal Dealer

Reply:Thanks for the tip, rlitman, I appreciate the advice.I have, with this torch, kept things quite clean, both sides. Always using new material and grinding mill scale and wiping with acetone. I have welded using other methods for many years, but this is my first TIG. I change the cups often, this is an older cup from another torch. I will check the other cup I was using as well for any particular heat issues. Thanks again.Regards,RobGreat Basin WeldingInstagramBlue weldersRed weldersMy luscious Table DIY TIG Torch cooler

Reply:Just as a parting note, I have had a lengthy discussion with CK's VP over email. He had also suggested I call but our schedules did not sync up. Needless to say I felt they have gone beyond what they needed to in order to help me solve my problem with their product. Something that rarely happens with most these days.I have decided to use a larger torch on longer or higher amperage runs and will keep a closer eye on my technique. Thank you all for your consideration as well. Great to be a part of this forum.Regards,RobGreat Basin WeldingInstagramBlue weldersRed weldersMy luscious Table DIY TIG Torch cooler
Reply:I have the same torch. Mine has over heating marks on it as well. I continue using mine as is and it seems to continue working fine.JasonLincoln Idealarc 250 stick/tigThermal Dynamics Cutmaster 52Miller Bobcat 250Torchmate CNC tableThermal Arc Hefty 2Ironworkers Local 720 |
