1 Answer

CP 302 wlder

Have voltage on Meter and can raise and lower the voltage but get no reading on Amp meter or no arc.

Fan is running and the fuses on the feeder are ok can feed wire
but no arc. or reading on the meter.

Trigger the wirefeeder while listening for the contactor on the CP302 to close, if it does start looking for loose, bad or missing ground connections to the work, then look for the power connection from the CP302 to the wirefeeder to be bad. If the CP302 contactor doesn't close look at the control cable between the wirefeeder and the CP302, try a different one if possible. If you hear the contactor close, and everything else is good, check the voltage at the CP302 output terminals to see if you may have a bad contactor.

Miller 130 wire advances, fan runs, but will not arc as wire comes out


Most of these machines (would have to have serial number to be sure) will not feed if their is no output voltage, since part of the motor voltage comes from the arc voltage.
So, I would suspect broken wires, either in the work lead or the gun. If it arcs just a little, probably the gun. One place the work lead breaks is right at the back of the clamp. Pull on the insulation and see if it "stretches". If so, the wire there is broken.

Welding troubleshooting


You could pass voltage but no welding current if the current carrying cable inside the mig gun has a break in it. Inside the mig gun is a braided copper current passing cable, if it only has a few strands of wire to complete the circuit it will not pass weld current.They usually break where the mig gun has been flexed over time.

Check the circuit breakers, one may have tripped or failed, such as CB4 which would also impact generator voltage output and since it controls power to the 24 control system- the first one to check or service. If you can access the rear terminals, check the voltage in operation at both lugs- if you do not get the same voltage reading at each lug of CB4 measuring them one at a time to chassis ground, the breaker is tripped or faulty .

CB1 is inline with the 240 VAC outlet and is ahead of CB2 and CB3

CB2 and CB3 are inline with the 120VAC outlets

In each case, switch them off then back on.

If you have the GFCI option, it may have been tripped by unsafe conditions.

Bobcat welder wont arc and the generator doesnt produce electricity


I had the same problem with another welder, if you have plug in or bolt on cables, unplug them

and clean them with a copper brush so that they can make a good connection, check your ground

clamp make sure its making a good connection as well as the electrode holder. if you have access

to an ohm meter make sure your machine is turned off when testing. set the ohm meter to rx1

and connect one side to the ground side of your machine and the other to the clamp at the end

of your cable if the reading is 0.00 a closed loop its good if all it does is flash you have an open. do

the same on the arc side. if you do find an open you may have to redo the connections. good luck!

Miller deltaweld 452 power source is reading EEE code in the voltage slot ???


Replace the digital meter board, its function is to also control the voltage to the unit and read the amps.

How i can use wire feer x-tyrem with a cp-302 welder


Hi:

An easy one: Connect your Suitcase X-treme 8 or 12 VS (volts sensing) as follows:

Weld Cable (+) To Feeder lead cable.


Work Cable ( - ) To Workpiece Weld cable and work cable connections to power source (DCEN/DCEP) are dependant on wire type.

Since feeder is not polarity sensitive, there is no need for an electrode polarity switch.


Voltage Sensing Clamp Connect voltage sensing clamp to

workpiece.


Gas Hose to regulator.


Gas Cylinder to regulator.

Use of shielding gas is dependant on wire type.


You are all set up to weld.


If this was useful. Please vote.

Wire does not feed motor does not run worked on all connections and it ran for about 4 feet then quit crossed trigger to see if that was the problem and got no wire any suggestions?????


does everything else work? power light come on? fan? does the trigger click? seems like you've tested everything i would have tested. maybe the motor itself. its also possible that theres an open in the wiring to the trigger. i would take the trigger back apart and do a continuity test from the beginning of the wire to the connection in the trigger. check continuity on both trigger wires. the best way to to do that is using a volt meter on either the continuity setting or resistance setting zero resistance or infanite (depending on meter) will mean there is an opening and you will either have to fix it or replace it. if you dont have a volt meter you may also try arcing across the two trigger wires closer to the welder connection.see i had this problem before but it was a faulty trigger so im thinkin if it isnt the trigger (you said you tested it) then its the trigger wiring.

The Voltage refered to is the Arc Voltage not the input voltage, for dip transfer the arc voltage needs to be 18-20v for spray transfer try 25-38volts both depending an the WFS setting. arc voltage is set on the voltage control dial. lets know how this turns out.#
