Cutmaster sl101 not working
There is a resettable breaker inside the machine that cuts off power to the plasmahead when tripped. Check that and make sure the head is secore to cable and cable is secure to machine.
If it still fails to function check the coil in the contactor to make sure it has not burned out. Also check the pressure switch to make sure it closes contacts to make the circuit when the unit is pressurized If switch is not functional the head will not operate. Also check gas solenoid or solenoids to make sure they do not have burned out coils as well. An Ohmmeter should show about 2000 ohms give or take some. The main contactor winding also. It may be the main contactor needs replacement- a loose power connection can lead to burned contacts. So if you hear the machine click when you press the trigger, but no power to head, and all the other items mentioned still leaves you with no power at the head, that main contactor is the likely culprit.
If IGBT's had failed- they would blow apart part of their plastic case.So a quick visual is usually adequate for those.

ESAB Handyplasma 550 XL31 is
Hi, when this happens it is usually a problem with the, electronics, often some, one? of the high power semiconductors, often the output ones, and it can often be a thermal cut out problem, however without actually testing and troubleshooting it's pretty hard to tell? These type of issues are among the most difficult to analyse, it's always easier when a device has failed completely, as this make finding the fault more clear cut.
Most often board replacement is the only way to repair, board level, & component replacement unless very skilled, is difficult so board replacement really is the only way to go. This is why one MUST get a service manual, if only for the parts numbers.
If you insist on DIY then you must obtain a service manual, use this and work through the troubleshooting procedures to try your isolate the issue.
Otherwise get a "Quote" from a professional, this way at least you can be appraised of exactly whats wrong, and also prospective costings and go from there?

The gas light come on
Gas light goes on when you have an air flow or pressure problem. Do you have enough pressure? you will need at least 120 psi at the compressor and 75psi at the plasma machine. Do you have enough flow? You will need 20 SCFH and a 30 gallon compressor reserve tank.
Let me know if this help. Please vote.

Is the esab 1250 worth
Esab's plasmas and machines are the best for manufacturing and shop maintenance. Are made for the tough jobs. Retail price brand new price is around 3200.00 US dollars.Cutting wise is a high speed cutting machine and will cut up to 1-1/2".

Need 2 know how 2
It needs to be at least 600 degrees F and should reach 800 or so. 60/40 solder melts around 600, but flows better at about 700 degrees. Most soldering guns require a on-off-on--- sequence to keep the tip at proper temperature. If your gun doesn't seem to be heating, try tightening the tip nuts. Hope this helps!

Doesnt turn on , i
To find out why the fuse keeps cutting off you will need to open that up and trace down the problem with an OHM meter...
You may find a black spot where it is shorting or arcing, but if not then the circuits will have to be traced and eliminated one by one till you find the source of the problem...
It could be anything from bad wire or connection to a bad transformer..

Powers on airs on air
inside the unit their is a part witch looks like a spark gap and that is what it is if this part gets dirty of has like a magnetic fuzz in it it will need to be cleaned as well the gap should be reset you will need to contact the manufacture for the specks do to different units have different settings wile you have the side off look for lose connections as well as arking marks for passable shorts their is a variety of things that can go wrong with thease units but what i said is most common do not use high pressure ari to blow clean a metal chip can damage transformer windings and then short out be careful of capacitors they can hold a nasty charge and aslo can be lethal if your not sure i highly suggest you take to a service center for the unit you have hope this helps.

You need to adopt an on-off-on---- action to control maximum temperature. Try to keep the tip so that the solder flows properly, but the tip doesn't try to burn up. Hope this helps!
