I doubt I can tell you, if you got the machine and can't read the panel.

Tip

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.

When using foot pedal for tig welding,does foot control ,increase voltage,and control the argon valve


The flow of the gas will be initiated and terminated by the use of the pedal, but it does not change the flow rate, just on and off. You will adjust your desired flow rate at your flow meter or regulator. I prefer a flow meter as I find them to be more accurate and easier to use.

The foot pedal will initiate and terminate the arc when used on a HF start tig welder. It works like a gas pedal. For example, if you have your machine set to 100 amps, by pushing all the way down on your foot pedal you'll get 100 amps. Some guys will set their machine wide open and just control the amperage with the foot pedal. I don't do it like that, although there is nothing wrong with doing it that way. I like to have a bit more sensitive amperage control. I will set my machine a little higher than I think I need and feather the foot pedal from there. This allows me to start at a low amperage and also taper off a bit smoother at the end.

Miller syncrowave 300 no power light and no weld power however have 480v input fan runs and can hear gas start when foot petal pushed


The first thing to check would be to see if you have open circuit voltage at the weld output terminals when you push the pedal. Make sure the high frequency is off if you are going to to check with a multimeter. After that if you do have OCV but no high frequency to start the arc, try it in start and in continuous. When you put it in continuous it bypasses a control relay. Also check the HF points to make sure they are clean and gapped to about ten thousandths.

Miller 300D I'm having issues striking an arc even when I have it turned up to 140. Or when welding the rod just sticks in the middle of a pass. Welding structural steel with 7018 1/8 Excalibur rod. Any...


The problem might be with your rods. It sometimes happen that the flux around te metal becomes soft if the rods were kept where there is a lot of moisture. If that is the case you can 'bake' the rods in the oven to dry it our. The flux must have a lower melting poit than the metal rod so that it can make a cup. The edges of the cup keep the rod away from the metal, allowing the arc to jump.
How do you 'strike' an arc? One method is to tick on the metal. A better method is to stike the rod over the metal like you stike a match. This action will give you the 'cup' that you need to start welding.
I hope it helps.

What electronic part is damaged?


Does the electrode stick to the metal? In which case your problem is with the elctrode or your method of striking the arc.

WHEN I TRY STRIKE AN ARC WITH A ROD YOU HAVE TO HIT IT 5 OR 6 TIMES TO GET IT TO WELD ITS HARD TO KEEP IT GOING BUT AFTER 4 OR 5 SECONDS IT WILL BURN LIKE NORMAL (USING PROPER AMPERAGE)


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 Lincoln SA 200 welder will not rev up when I strike an arc.


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