Thermadyne predator has one cylinder not firing

Contact a local welding supply vendor, they should be able to direct you to someone qualified to do the job.

When you turn on the power are there any sounds or lights coming? If not It sounds like a power supply problem, which is quite common. You need to get a tech to check its outputs. A replacement one is not too expensive and fairly simple to fit, but you need advice to get a quality one

If you are using a remote then you would set the machine in standard for controlling output and also to AC output, HF tig, contactor and control in remote position. I don't know if this helps or not but I pulled it from an owners manual.

1/16" (.062) - pre-flow .1 sec., hot start 20, amperage 70, Hz 100, balance 20%, post-flow 6.0 sec.

For pulse settings - set pulse width 60%, peak current 100, background current 30, Hz 1.0

1/8" (.125) - pre-flow .1 sec., hot start 20, amperage 150, Hz 80, balance 20%, post-flow 6.0 sec.

For pulse settings - set pulse width 60%, peak current 150, background current 50, Hz 1.0

3/16"-1/4" - pre-flow .1 sec., hot start 20, amperage 185, Hz 60, balance 20%, post-flow 8.0 sec.
For pulse settings - set pulse width 60%, peak current 185, Background current 125, Hz 1.0

Check your manual or the welding rods data sheet. The settings depend on what you will weld. Consult online manuals and welding charts. These will help you a lot.

Go to this site and you can download or print a manual for your welder copy and paste to google search engine and it has the manual on pdf. TRANSTIG 200 AC/DC Servic Manual - Victor Technologies

If your gun end is a Tweco, those are pretty much standard and readily available from welding supply houses. If the retainer for holding the liner is broken you would get that through Thermadyne.

Cylinder 1 is not firing or is intermittently firing. Check the output on the coil associated with #1 cylinder by using a spare plug attached to #1 wire while engine is running. If it has good spark, check the fuel injector for possible problems. Crank shaft sensor would not be the problem as the engine has to have it to run. You may need to have it checked further at a reputable repair shop as this can get more involved than a back yard repair.

Check this manual. It's not for your exact torch, but the parts are about the same. You should be able to go to any welding supply hose and buy parts or have your torch repaired.

Has an 8 amp fuse in series with solenoid, also has a relay which operates off the PC Board. I would suspect the relay as long as the output is not shorted or grounded causing continuous current.

Try this one if not it go to the next link for manuals.
