I purchased this unit on Friday not working.
When we turned it on the power and pressure lights came on and the internal fan ran.
When we pulled the trigger nothing happened.
That was due to the pressure light being on.
Today we cleaned out the blocked internal water trap, cleaned the torch and blew out the dust.
When reassembled and turned on the power light came on. At this stage the output was set at 20. When I turned the output knob counter clockwise to the Gas/Air Set the solenoid pulsed off and on shooting air through the torch. The pressure light was flashing at the same time. While this was happening I turned the output knob clockwise until it reached the first setting, this stopped the solenoid pulsing. The power light was the only light on so I pulled the trigger and air came out of the torch. No pilot arc came on but that may be because the tip and electrode need replacing. When I released the trigger the pressure light was flashing. I have checked for blockages from the compressed air inlet to the torch tip all good. Sounds like a pressure switch or a PC board issue.

I've had the pulsing caused by use of clone tips and nozzles cut wrong and alowing too much air to escape so as to not alow the electrode to move back off the tip making the spark to ignite the pilot arc
Does the electode have movement when you put the nozzle on?

I read some old posts last night about not tightening the nozzle. Was going to try it today. Never thought that the tip and/or the electrode would be non Miller. I rang every welding supply company yesterday trying to get new tips, electrodes & nozzle but being a Saturday no one was open or they had to order them.
You are probably correct because there is no movement of the tip at all.
Will ring around again on Monday.
Is it normal to have the fan running when you turn on the machine?
