Question about Lincoln Electric Plasma Cutter, Pro - Cut 25

Open Question

Have to hit nozzle to work

We have a pro-cut 25. We set up according to instructions, but have to strike the back of the nozzle to get arc started. We had the problem and replaced the entire nozzle assembly and hose, but the same problem persists. Any ideas?

I am trying to figureout why mywelder runs off when you strike an arc?It seems as if it shorts out and starts to bog

Check the gas ports found in the diffuser, and on some consumables brands, in the nozzle. These holes can also become clogged with spatter and restrict shielding gas flow to the weld pool. These components should be checked several times throughout the day, even if a shielding gas problem isn't suspected.
Inside the gun cable is a hose that contains both the liner and the shielding gas. This hose can also fail from overuse and holes can be created inside of the cable, through which gas can escape and you would never see it. This problem is mostly caused by using too small of a gun for the amperage being used to weld and from the constant flexing of the gun during use.
The inside diameter of the welding gun nozzle can also have an impact on shielding gas delivery. If the nozzle diameter is too small and gas flow is set too high, a venturi-type of effect can occur, drawing in the atmosphere and contaminating the gas supply. Also, if the nozzle is too large in diameter or the contact tip extends too far from the end of the nozzle or if the contact tip-to-work distance is too great, shielding gas coverage will be impacted.
Without good electrical flow between the power source, wire feeder, lead cable and work cable, you could experience a variety of problems, including a sputtering arc, excessive spatter and reduced equipment longevity. The best way to avoid these problems, or troubleshoot them when they occur, is to verify that all of the electrical connections between the welding components are tight and secure.

Prone to arc eyes from welding?

If you have a conventional flip lens welding helmet and are prone to getting arc eyes from "peeping" though a gap to strike your arc, try this.<br /> Replace the inside fixed clear lens in your helmet with a yellow perspex lens. The world will appear strange at first through the yellow lens, but the yellow cuts out the ultra violet rays that cause arc eyes. The yellow lens should not be considered a replacement for the dark glass, it is only to shield you from that inadvertant flash when making your strike.

Quite old but unused AC 225 S.strikes an arc,can weld about an inch,cuts out...short while later ,same thing

Most common problem would be with technique if this is a buzz box type welder. It is tricky to maintain the right arc and speed to not have arc go out. You need to use a voltmeter to check what is happening to the output voltage. If it disappears, search for a bad connection on the inout power. This could be clear back at the breaker or anywher to the welder. If the fan continues to run, then this is not the problem. Check the switch contacts on the heat setting switch.

Shuts on on safety ,,almost immediatley

Check that the tip is assembled correctly.If is not in properly, it will not arc. Second, check air pressure switch. Sometimes they become stuck from corrosion due to moisture in the air. Test the operation with a tester

Is this on new rods as well as one's you'be been already welding with? Depending on rod types, some will "flux over" the end, after welding insulating the tip. When you're welding at a low setting, with a small rod, sometimes it is hard to start an arc. A 7018 rod is a good example of this. Strike the rod like a woodden match, or drag it on the metal, to expose the rod. It also depends on your welder. Some have settings to help start an arc and then control the current. Older transformer welders arn't that smart and are less forgiving on low current thin metal settings.

My rca model f36669 makes a popping sound and cuts off and back on

That's hi voltage arcing. Dangerous condition were a component has broken down and is arcing causing the power supply to 'crowbar' or go into over current protection mode. Call a TV repair pro for an estimate to see if you want to keep the set.

Need code number to be exact, but sounds like the wiring to the current transformer is incorrect.

Pulsating Arc

Sounds like one or two of the power diodes are defective (open), producing a half wave pulse instead of full wave, giving it a dotting effect.
