Question about Welding Tools

1 Answer

I have endless problems trying to feed .8 stainless wire through an ESSAB Compact 200 Mig. .9 mild steel feeds reasonably well but the stainless constantly knots up near the entrance to the liner, after the feed rollers. Which type of liner is best for stainless? Is it ok to swap different wires with the same liner? Mark.

Probably the gun housing it's missing the inlet guide to the gun, there are two types of inlet (outlet if you see it that is located after the drive rolls) guides: one is made out of plastic and the second is made out of steel tubing (this one is more common on the 250 A machines). Just to make sure that you have one, take the gun out of the hosing and check that inside you have this plastic (or steel) tubing (about 4-6 inches long don't remember exactly), if don't; the go to your nearest welding shop and buy one. You might want to talk to your sales rep about this problem, it's real easy to fix.

Also you may consider check that you are using the same size drive rolls .8 (.030) as the SS wire in use.

And yes, it is ok to swap different types of wires with same gun liner. Just make sure is the right diameter.
Good Luck.

Settings to weld 2.5mm mild steel with rossi 130amp mig welder

set the volts to around 20 and then adjust the wire speed to obtain a good arc
wire feed speed also adjusts the volts but you have to in the area as the feed is like a fine tune
adjust the volts up or down to get a good weld
practice on scrap to get it right

Lincoln pro core 125 won't feed on c or d

If this is an old machine the reason it's not welding on C or D set is because the voltage control rheostat it's worn out or just dirty. Open your machine and take the rheostat out (also know as petentiometer) and inspect it for carbon build up along the spring try to clean it with a stainless steel toothbrush if problem persist then just buy another control.

Newer welders as hobart and miller are set up from factory to use innershield wire therefore polarity is set up as inverse. Check inside your machine and check that ground cable is on negative side. Your gas must be mix argon/CO2 or pure CO2 (not recommended).
Other potential problem is wire not being a mild steel one. Check you have gas flow out of your nozzle.
That's all I can think of.

Clark 130en does not feed well. Feeds great on 10

try checking the tension on the feed roller,you may have too much tension which in return will not allow the wire to feed right,check to make sure your feed roller is for the size of wire you are using,next check the tip size for the wire your using.

I dont know what kind of metals this wire type can do, it says fire power 1440 u235 flux wire, but not sure what kinds of aluminums or steels it can weld. Im a certifed MIG aluminum welder, but this is a...

Usually a flux core only welds steel. It is a higher penetration weld than a MIG. Usually it acts similar to 6011 rods in SMA (Shielded Metal Arc) welding -- a.k.a. stick welding -- if you're familiar with that. I don't believe there is such a thing as flux wire for aluminum. There may be stainless wire for it, but I've never seen it. It probably could also be used for building up cast iron and cast steel, but nothing structural. I have a Chicago Electric one and I love it -- simple and it penetrates hard. My 90 amp will weld to 3/8" without breaking a sweat and if I baby it will go to 1/2" or better. It is difficult to go much lower than 12 or 14 gauge though due to the high penetration.

I'm having a problem with the wire feed on my Lincoln Pro Mig 140. The wire feed speed is not consistant. It seems to be slipping even though the tension is tight. Any solutions?

Mig Question

MIG stands for Metal Inert Gas welding, many times called Wire-feed.. Also referred as GMAW (Gas Metal Arc Welding). The "Metal" refers to the wire which is what is used to start the arc. It is shielded by inert gas and the feeding wire also acts as the filler rod. A semi-automatic process, it is fairly easy to learn and use.
