Question about Lincoln Welding Tools

1 Answer

I have a power MIG 216 and when you set the wire speed and start welding it changes speed and is not consistent...I've watched the drive system while a friend welds and it stays consistent, just not at tip while welding....is this a liner issue?

Potentially, I would tighten tension on the feed wheels slightly first and see if this improves it. Also blow out the cabinet on a periodic basis as debris can also build up in the knurlings of the feed wheels. If it does not, pull out the liner and check it for kinks or other damage.

SOURCE: SP-250 power supply problem

When you pull the trigger the wire should feed imediately, if it dosn't then this will give you the problem. first check the clutch on the wire spool, this is in the centre post that the spool goes on the nut/screw should allow the wire spool to turn easly without tention,
if the spool runs on adjust the cluch. Check the shaft that the rollers are atached they should be held with key-way to stop them slipping, re-adjust the WFS ensure the wire feeds fast or slow as you rotate the WFS control and ensure the wire feeds instantly, lastly make shore the rollers are correct: the right size

SOURCE: Welder not welding

SOunds like your ground is not connected solidly either inside the machine or at the ground clamp. Check to make sure the ground wire at the clamp is not broken then make sure the ground wire is connected solidly inside the machine.

SOURCE: wire broken off inside of liner in mig gun hose

about the only thing to do is take the gun of the unit ,place it straight in line on the floor or bench and try to hand feed the wire back the other way.good luck,this will be a lucky thing if it works.i dont understand how the wire broke off in the first place.

I had this issue on my el-cheapo mig welder.The wire drive on the junk or the good machines is similar as far as how the wire is pushed down the liner.A pair of spring loaded wheels squeezes the wire,and one of them is turned by the motor.One of the wheels has a groove to keep the ire aligned.This groove is possibly worn out,and not gripping the wire enough.(My cheap welder,unbelievably,has a reversible wheel with a second groove.I turned it over,and it's like new again!).You should have no problem in getting a replacement wheel for a Lincoln machine.

Wire feed speed problem


Check the speed control board's voltage from the fan. If you are below 20 volts, 1- oil the cooling fan bushings to see if that helps. Otherwise adding in a discrete 24 volt 1 ro 1.5 Amp "control" transformer and a 2 ohm 50 Watt resistor in place of the fan's 24 volt tap (it rarely gets to 24 volts) should bring your speed up.

This does assume the board is fully functional.

The arc sputters when welding. Tried changing the electrode tip and checked the ground.


I've had slot of experience with these migs. Usually when the arc sputters, it could mean 2 things, either the roller feed tension is too light, or the liner in the pistol lead is worn. It's the flex tube the wire travels through. If it's worn the wire will hang up or snag, causing the arc to sputter. If you tighten the roller tension, and the wire back-lashes, that's a sign to change the lead. First try adjusting the speed of the wire accordingly to the heat.

Why does gassless mig wire splatter


Hi there, Sounds like the stick out is to long (wire length from puddle to tip of gun.You can vary the voltage by raising the tip.Without seeing you welding it's hard to say.If your wire speed is to fast(controls the amps) or the angle isn't right you will see golf balls which means your running to hot.One other thing the flux can draw moister and cause problems.Check out this link for further help.Tip:old fridge will keep out the moister or a dead microwave.L(8^) Thank You for choosing FixYa.com the few vids I watched were gas mig,but pay attention to the sparks, flux wire will tend to spatter more but if everything is set right it will brush right off.Fastnall(nuts,washers bolts) has 2# rolls of wire for the same price as Lowes 1# rolls.Enjoy the vids and thanks for choosing FixYa.com

216 mig no feed no fire maybe selonoid problem please help seloniod does not click


It could be just the simple problem of the trigger not working. Disconnect the trigger wires from the machine at the plug at the front of the machine. See if you can manually trigger the machine by placing a piece of bent over mig wire onto the contacts. If the machine does trigger from this then your fault is in the torch somewhere. It could be the trigger (which commonly does fault from a dusty environment) which is easily replaced by going into any welding store with the torch model number (magnum 250L), or it could possibly be that a trigger wire has broken from the torch being damaged

I have a Lincoln 140 mig welder. It welds and cuts


Usually this is caused by a bad liner in the mig gun hose, or worn out guide rolls in the drive unit, or if this is not the case the speed of the wire might be set to high as this would force the wire into the weld causing the motor to heat up from resistance and shut it down on safty. Hope This Helps Don

Trying to weld with Hobart 125 EZ


If you are using flux wire and not shielding gas, your clamp should be positive and the wire should be negative. Heat is provided by the electrical arc that happens between the wire and the material. Your welder by itself does not pre heat the material and with 3/16 material you should not need to preheat anyway.

The electrical arc is kept consistent by adjusting the wire feed rate and the current applied. You will need to experiment with these settings to find what works best with your welder. For this welder and 3/16 material, I would suggest you start at the upper end of the current scale and about a third of the way up on wire speed. The welder might have a chart for these settings in the manual or inside cover.

If the wire feeds too fast, it will push the probe around and you will feel pressure as the wire feeds out. If the speed is too slow you will get large spatters and intermittent arcs. When properly adjusted the arc will sound even and consistent. The arc gap should always be about 1/8 of an inch.

To maintain enough heat for good penatration, do not move the probe too fast, work in a pattern and watch the weld pool (melted metal) and not the arc. Watching the weld pool will clue you in if you are moving too fast or too slow.

I hope this helps.
