Question about Hobart Handler 140 Mig Welder

1 Answer

Have an old hobart handler, wire goes fast then slow etc. already

Have a new liner. We are wondering if the neg and pos leads are incorrect inside the machine, as it is the neg now goes to thur the wire side and the pos is now thru the neg clamp back to the machine. This is an old machine used very little, can get a ok bead on setting 3/ 6.9 but still spits some on the wire feed. Tryed moveing machine to 30 amp outlet not much better with more amps avaliable.

Convert battery cables from top post to side mount replacement ends?


If all you are doing is changing to a side post battery, just connect all the positive cables from the old pos post to the new pos holder and all the neg ones to the new neg holder. If you've already cut them all off and not sure where each wire goes, all the reds are positive, all the blacks are neg. To make sure use your continuity meter to test. Connect one meter lead to any good clean metal part on the car and test between each black wire in turn, the neg ones will show a circuit, the pos ones will not.

I have a hobart Handler 135 and it won't feed the wire correctly. At first it will feed about 6 " of wire then it goes down to about an inch at a time then it will just click. If you wait awhile it will...


If you completely remove wire from unit does it still slowdown and stop when you pull trigger?
If yes, then 2 most common problems are
A. Thermistor @ position PTC1 on circuit board
B. Drive Roller Motor

To diagnose, locate thermistor @ position PTC1 in upper middle part of circuit board.
It's yellowish round and about 1/2" in diameter.
Jumper Accross the 2 leads, use a small insulated screwdriver or meter probe.


1. Pull trigger on gun, when motor slows or stops then jumper the leads, if it speeds back up then it's the Thermistor
Replace with a Raychem RXE 1.85A @ 72 v
Or comparable, try EBay

2. If no change, isolate motor by removing the 2 leads and connect a 9-12 volt DC battery source, does motor spin? If not then motor is problem. If motor spins and is constant then additional troubleshooting needed, next possible issues are bad resistor or scr

Wire feed is not stable on Hobart handler 135


is this a lower end machine ? the cheaper machines take the power from the welding transformer to power the feed motor and as a result the feed isn't stable, also is the wire liner and tip in good condition if not replace them, try blowing through the liner with compressed air to clear any dust from the wire

Hobart handler 135, the wire starts to feed for about 15 seconds then slows and stops.


Hi:
Don't know how old is your unit but my guess is that your gun's liner is the problem. Have you change it lately? If not, change it. Does your machine just stops feeding the wire or does it shuts down? If it just stop then; is the liner, if it shuts down; then you have a pc board problem.

I got some lose wire stuck in my leads on the welding machine where instead of the wire sticking out of the nozzle it is on the other end and i can't pull it out from that side. I don't know...


Hi:

You are worrying too much, just take out the inner liner and replace it for a new one. A liner will cost you around 15.00 and it is pretty easy to change. Check your onwers manual or email me for step by step liner replace.

I purchased a used Hobart Handler 140 and I think it might have a problem. No matter what Amperage setting and wire speed I can't get any penetration. I am using .30 flux core wire, no shielding gas....


Hi there,
Sounds like you liner may be bad.There is a plastic tube that the wire travels through to the gun.The teeth marks from the feed wheel acts like a saw and can cause a short.Then the liner carry's part of the voltage.Look for a blue color on the liner. Here is a video that shows how to change a Hobart liner .You may want to multi test first for contanity with the power off.

Thank You for choosing FixYa.com.

Gauge showing low output alt only 1yr old wondering if it could be regulator or batt or wiring


if you have access to a digital multimeter, connect the meter (set to volts) across positive and neg. terminal of the battery, should read roughly 12.6 volts, close to 10 volts, battery may be going out, also test the alt output, disconnect neg term and place negative lead to battery neg post and positive lead to neg battery cable (make sure meter is set to amps) should read near the rating, if both those, then you'd want to do a resistance test, (set meter to Ohms) disconnect battery and connect meter neg to either pos cable terminal or where the pos cable connects to the alt and connect positive lead to opposite of neg, should read next to 0, the check resistance of the ground by connecting meter between batt neg cable and body of alt.

Wiring diagrams for clarion dxz535 car stereo


Here's how it goes:
Speaker wires:
grey=right front pos.
grey/black=right front neg.
white=left front pos.
white/black=left front neg.
violet=right rear pos.
violet/black=right rear neg.
green=left rear pos.
green/black=left rear neg.
red=12 volt switched power source
yellow=12 volt constant power source (direct to battery)
black=chassis ground
orange/white=illumination (switched source,not to head light switch)
blue/white=amp turn on lead (to remote turn on lead of amp)
blue=auto antenna (switched power source)
brown=phone mute lead (to cell phone mute lead)
RCA connector leads:
grey lead:
red=right front
white=left front
black lead:
red=right rear/right rear subwoofer
white=left rear/left rear subwoofer
(connect to external amp)
red lead:
red=right aux input
white=left aux input
(connect to external unit)
green lead:
red=right dual zone output
white=left dual zone output
(connect to wireless head phones)
That should be all there is. on the yellow that goes direct to the battery you need to use an inline fuse holder with 30 amp fuse.

Have 36 volt club car w/coils


Recheck your battery wiring. The batteries should be wired in series, neg to pos to neg. I believe one of the batteries behind the driver's side is the main negative and one on the passenger side is the main positive. There is usually a #6 green wire coming from the for/rev switch to a positive battery post, however , it might be a different color, but that one is the reverse wire, It can be on any positive post, just count the number of batteries between green wire and main neg, multiply by 6 and that would be total reverse voltage. If wired correctly all 6 batteries are used for forward.

You can replace the liner by removing the shroud tip, and pulling the spring (liner) from the machine end of the trifgger cable.
Liners are replaceable.
