wondering if anyone can help on my welder

[grsthegreat]

also on mine, if i dont set the tension correctly on the feed roller i get sporadic feed of the wire.

Thanks for the feedback. I will run some more checks on it tomorrow. What would cause the liner to go bad? Can you clean it out?

If it is the liner, should I get a whole new lead (longer)?

I will check out the tip and liner, as well as the roller speed. What IF the roller speed varies? Roller tension or something else. I adjusted the tension up and down, didn't change anything. Did not watch speed of rollers though.

If you didnt actually watch the speed of the rollers, my money is on something simple like tension or the liner.

The liner is typically a peice of what looks like a spring. Just a long tightly coiled peice of wire. The coating they put on the mig wire as well as just abrasion particals over time tend to gum it up. They are typically not too expensive, but can be a PITA to change. A whole new lead is going to be a lot more $$.

Watch the feed roller (not the tension roller). It should turn a consistent speed when you depress the trigger and hold it. If it turns a consistent speed it lets you know the switch, relays, motor for the roller are all good. Once you have verified this then try different wire speeds to to see if roller speeds up and slows done when you change wire speed setting - lets you know potentiometer adjustment is good.

As mentioned in my previous post: Liner is cheap (under $20) for a universal one. Longer lead will be much more costly and probably exceed the value of this aprticualr welder.

Liners are considered a normal wear item on all Mig/wire feeder type welders. Few people have had any luck cleaning them since the problem is often more than simply being gummed up. Sharp galded edges inside the liner from steel to steel wear. Using cheap wire seems to be harder on liners. Also, the liner can even get out of round from people stepping on lead which I have been guilty of doing. I just had to replace my liner on my Lincoln SP-135 and it was relatively easy although I must admit that I had not ran a great deal of wire through the machine but I had used some cheap wire. I plan to only use reputable wire from now on - hope it helps with liner life. Also, I will pay more attention and never step on the lead.

Check/replace the contact tip. This usually is the problem. If you have a tip cleaner the right size, you can clean the tip and try it again, but you don't want to oversize it. Liners can be blown out gently with compressed air. This may or may not work in my experience. Sometimes it makes matters worse, but worth a try before replacing it. Like was said, confirm that the drive rolls are turning at a consistent speed and they are not slipping. I would do this with the contact tip removed. The proper way to set tension on the feed rolls is to back it off until you can stop the wire feeding when placed against your hand or another object, and then increase tension until you can just barely stop it. Any more than that just deforms the wire and causes feeding problems, especially with a cored wire. Worn out drive rolls might also be the problem. I wouldn't recommend a longer gun cable. That just increases the feeding resistance.

OK headn out there soon. I have run over the lead a few times with the welding cart, wonder if that has done anything. I will report back.

Ok the LOOOOONG awaited report:thumbsup:. It was the tip that was clogged up. I guess doing a lot of welding with the flux core does have it's drawbacks.

I used the tip cleaners from my gas setup. One thing I noticed, is I still had the .030 tip on there from when I was using gas and .030 wire, duh. The flux core I have is .035. I need to pick up some tips next trip to the welding shop, I suppose. get some spares. Are there different size tips, as far as the threads go or are they universal?

Thanks for the "tips" (pun intended) on how to research my problem.

Tips are usually unique to the brand of welder. But just take in an old tip to your welding supply shop and I am positive they will be able to help you out.

OK thanks, will do.

Glad to hear that your issue was so minor. If I recall correctly, you were ready to go out and get a new welder (I might be thinking of a different thread). Ain't TBN great?:thumbsup:
