Charlotte Posted October 6, 2015 Share Posted October 6, 2015 I re-acquired a 120 volt century power matic 100 wire welder the other day. It had been on loan for a long time and evidently never used or not used enough. It seems that the liner has gotten dirty or maybe oxidized. At any rate when I pulled the wire out it had occasional dark spotting and felt rough to the touch in many places. Question: Is there anything reasonable I can do to restore the liner, or do I need to replace the steel liner? Quote Link to comment Share on other sites More sharing options...
the iron dwarf Posted October 6, 2015 Share Posted October 6, 2015 they need replacing and I consider them a consumable, I keep a few spares Quote Link to comment Share on other sites More sharing options...
Alan Evans Posted October 6, 2015 Share Posted October 6, 2015 I have not had a problem with the liner from lack of use, but have often had to unreel a couple of layers of rusty wire from the drum before I use the welder again.If the wire is not snagging in the liner and if the liner is not rusted through, it will soon polish inside up with use I would think.Alan Quote Link to comment Share on other sites More sharing options...
yahoo2 Posted October 6, 2015 Share Posted October 6, 2015 you can pull it to bits and try and run some compressed air through it gently. maybe use some acetone like nail gun or brake cleaner. the old trick of using a clothespin and a bit of rag clipped to the wire or one of those alligator paper clips and some scotchbrite keeps the crud out of the liner.

Charles R. Stevens Posted October 7, 2015 Share Posted October 7, 2015 The linner is infact a consumable. Our miller eats them up wile the hobarts rarely do. Their is a kit that has one or two felt pads and clips pluss a cleaner and lubricant for areas with himidity isues. Quote Link to comment Share on other sites More sharing options...
Smoggy Posted October 7, 2015 Share Posted October 7, 2015 I got my mig for a song as it wasn't working, replaced the liner, fiddled with the settings, job was a good one!As a life long Gas and Stick man ...... All I need to do now is learn to use it! Quote Link to comment Share on other sites More sharing options...
jeremy k Posted October 7, 2015 Share Posted October 7, 2015 One of the biggest problems with liners getting clogged - is the wire tensioner is to tight and small particles come off the wire and pulled into the liner and collects in the liner to eventually cause troubles and jamming. Liners are cheap - replace it and don't look back. Quote Link to comment Share on other sites More sharing options...
T.J.watts Posted October 7, 2015 Share Posted October 7, 2015 As these gentlemen have already suggested, replace the liner and use the felt pads with cleaner. As maintenance on my machine at work I blow out the liner and lead about once a month. Quote Link to comment Share on other sites More sharing options...
Charlotte Posted October 7, 2015 Author Share Posted October 7, 2015 Thank you for the advice. Btw what is the cleaner you folks use and what goes on the felt pad. I decided that I will have to try to buy a liner. To do anything I will have to disassemble the gun and machine connection any way. In for a penny in for a pound or some such.

Charles R. Stevens Posted October 7, 2015 Share Posted October 7, 2015 Thal to your supier, they generaly have the replacement liners and the pads and cleaner in the same area Quote Link to comment Share on other sites More sharing options...
Charlotte Posted October 7, 2015 Author Share Posted October 7, 2015 Charles, in the normal course of events that would be the expected course of action. Problem is this machine is many years old and a discount brand.I found a supplier in Cleveland, OH. They are a factory authorized dealer for Century Mfg. Turns out that this machine's liners are a crossover with Lincoln. At a guess I say it's design is simplified low price version manufactured under license.I had an uncle in a different industry that set up those deals for his company. That is what give me the idea.

ianinsa Posted October 7, 2015 Share Posted October 7, 2015 The machine itself is not really that relevant it's the design of the torch i.e. A Binzel torch, many brands use a design or clone/copy of say Binzel's design. Take the torch and hose off, and take it in, the guys in the shop should be able to tell you what type it is! (presuming they are worth their salt that is) and this will help you in future when buying consumables. Quote Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted October 7, 2015 Share Posted October 7, 2015 Iqn is right there arent that many styels of liners Quote Link to comment Share on other sites More sharing options...
Charlotte Posted October 7, 2015 Author Share Posted October 7, 2015 No doubt you guys are correct. For this machine there are two One for al wire with Teflon and the second for iron wire or so it appears in the parts list. Quote Link to comment Share on other sites More sharing options...
John McPherson Posted October 8, 2015 Share Posted October 8, 2015 Historically, most small US companies reboxed or relabeled consumable componenents from one of the major brands of welding equipment. (Sears seems to be the exception.) There are still only a few types of MIG and gas cutting tips. Students bring me their CL/garage sale finds, and we can usually get them up and running.Recent off-brand imports, however, are a totally random field, and machines become orphaned and obsolete as fast as cell phones and computers.

DSW Posted October 8, 2015 Share Posted October 8, 2015 I'm surprised that you think Sears to be an exception to rebranding as most of their stuff for years has always been made by someone else ( though in some cases made to Sears specs) 1st 3 possibly 4 digits of the Sears part number usually calls out who made that item for Sears. For example 642.XXXX would denote that Harris manufactured a Sears branded welding regulator/torch set. 934.XXXX would be Century Welders.

John McPherson Posted October 8, 2015 Share Posted October 8, 2015 Sorry for the confusion, I meant that Sears changed suppliers like most folks change socks, never sticking to one brand. Whoever bid low got this year's model run. One year it is Victor tips, next year is Airco style. And the regulators! Hopeless. Quote Link to comment Share on other sites More sharing options...

yahoo2 Posted October 9, 2015 Share Posted October 9, 2015 Btw what is the cleaner you folks use and what goes on the felt pad. nothing on the felt, the cloth only dislodges the dust on the wire before it gets to the liner Quote Link to comment Share on other sites More sharing options...

Charles R. Stevens Posted October 12, 2015 Share Posted October 12, 2015 Here with the humididty and not welding every day (or month for that mater) it realy helps. The industrial wool felt dose a good job of scoweing of the rust and a little slickum makes for a more consistant feed. On the miller I instaled a boom to hold up the snake rite at 6" from the machine, as gravity tends to kink it right there. Quote Link to comment Share on other sites More sharing options...
Charlotte Posted October 12, 2015 Author Share Posted October 12, 2015 Appreciate the heads up about the Kink. Have a real appreciation for the effects of humidity two miles from the Mississippi River and three from the lakes next to New Orleans.
