the digital display is just showing what is going on the amperage is controlled by the voltage setting so the problem is most likely in the voltage regulator take it in for a proper diagnosis and quote but guessing the fault is like throwing money away

Hello Mark, There are many things that can cause a machine to not come on. Start from the basics and work to the hard. Check and make sure there is power to the receptacle, then power in at the machine where the main power connects to the power block inside. You'll also need to check the power switch and see if power is getting that far. If all that checks out ok, then you have a more serious problem that is not likely to be repaired through a few short messages. Also, do not attempt to diagnose anything unless you are comfortable and knowledgeable enough to work with live electricity. Good luck, Ryan

reset you wire feed speed and the voltage for the thickness of metal being welded it indicates that the voltage is far too high -probably to compensate for the high wire feed speed gas is wasted at that flow rate set up welding screens around the job to stop breezes interfering with the gas at the tip the gas at the tip should be flowing only strong enough to maintain a gas bubble around the arc That is the purpose of the gas is only to displace oxygen and so give a good weld

Shorted transformer is my guess.

indicates the following problems rusty wire in use-- the rust builds up in the inner wire and will not allow free movement the inner cable is worn and is grabbing the wire in a groove -- the inner cable will wear a groove and that catches the wire in certain situations -- the feed rollers are worn or the wire in use is not correct for the groove in use most feed rollers have 2 grooves and each one is for set dia wire there are different rollers if gasless wire is in use to prevent the wire from deforming as it passes through the rollers

check for power to the gas solenoid when you press the weld trigger

sounds to me that the sealing o-ring or gas block is cracked ? maybe from pulling machine by the cable?? ( ohh what welder would do that ?) id remove the cable from the gas block and ck both of these items , both are replaceable O-rings are cheaper of course (take care to be looking for trigger switch wires there too )

Here is a copy of the engine operations from the manual.

look for a bad ground wire connection ---in the plug , clamp, position of the ground clamp surface,cleanliness( paint, rust etc) place the ground clamp as close as practicable to the welding point

There is very little maintenance that needs to be done. Take the covers off of both the wire feeder and the welder and gently blow out the dirt. Do not just blast everything with air as you could create problems. If everything is working right don't worry about anything else.

weld current and idle control on this machine is controlled by the main circuit board, you mention that you a second ranger 8 that does not exhibit the same problem, you are fortunate in this, remove the board from the functioning machine, install it into the troubled machine, this should correct your problem, you can contact a weld supply store to purchase a replacement pc board

If this is a Lincoln Ranger, could be the switch or the circuit board.

all wiring connected inside by the wire reel, like where the power comes into that area so you can reverse the polarity. is the machine powering up? Lights on front, fan running etc? wire moving through liner? Check your ground clamp wire, make sure the liner is making contact inside the gun tip. Check plug wiring on both the welder and the socket, makes sure they are both wired correctly as well as tightened down securely/ I've seen plugs that were new from factory but had 1 wire not connected to a post, cut too short and just left it. also check that the outlet is wired the same as the plug on the machine. they need to have the 2 hot wires correct you'll see red, black, white & green. red & black are hot and need to go to the red and black from the wall.

what model AND code is the Lincoln?

sounds like 4 hours of welding meets the welders 'Cycle time'

Which model?Lincoln does ahve the diagrams in the manuals available here:Operators Manuals ' Lincoln Electric
