The gas won't shut off once I release the trigger, sometimes the wire continues as well.


Hi:The solenoid valve gets the current once the switch is activated (pressed) therefore my opinion is that you have a sticky trigger. or one of the terminals of the cables it's shorting out.Change the trigger or better yet check that the terminals are clear and not touching other parts of the handle.

Would you purchase the 400 hobart or go to 500 hobart plasma they seem to cut the same thickness on the metal chart..


It's all about duration. How much metal do you need to cut continuously. Although the 400 will cut a similar spec it won't hold out as long. So if it;s lots of short cuts the 400 is fine, if you need to cut thicker gauge for longer period go 500.

Poulan WT usually starts Ok but after it is used for 8-10 minutes it cuts out when when trigger is released. Happens mostly when you're cutting & then release trigger when cut is done.


If the carb hasn't been rebuilt in a few years, often the fuel pump diaphram gets weak or the little flap check valves get deteriorated. Carb kits are about $20.

Breaker blow


You may have a short in the trigger leads that is pulling the weld current back through the leads and through the control cable. The short could be causing the breaker to blow. Can you open up the gun handle (disconnect it from the power source first) and check your trigger leads for cuts or nicks. Also check the outer jacket of the cable for cuts which may be deep enough to allow the current carrying copper to touch the embeded switch leads.

Only cuts for 3 seconds, device still on


Possibly an internal short in the torch tip... the expendable components failing in the tip will cause the sensors in the machine to register a "no cut" or "free air arc" state and kill the power to the tip to prevent damage to the unit. Replace the tip components and double check the grounds connections.

Motor cuts on 2-3 seconds and then off and repeats this pattern


There are several possible causes of this problem. The three simplest to check are: 1. water supply is not sufficient, 2. water inlet strainer is clogged, 3. nozzle in the spray lance is partially blocked. After those, the most likely problems are internal and will probably require professional attention.

Hobart 250 a keeps cutting off the flame


If you have a bad air supply then the moisture in the air will cause the torch to cut off and the cut quality depends also on air supply,speed,metal thickness and condition of your consumables,meaning your electrode and other related parts in the torch tip.Hope this helps
