Question about Hammering

1 Answer

Have no weld or power output from a miller starfire 2e, will give very small spark on electrode, but nowhere near enough to do anything, any ideas? brushes are new, cleaned slip rings, checked diodes on exitation rectifier, all else looks good, when electric drill plugged in, starts to turn slowly, but nothing else.

Did you check the breakers im talking about the ones on the unit either switch or push button you can only reset them so many times what happens is there like a set of points in an old chevy they start to get pitited bigger the pits the less power you get less amps are produced just because the reset dosent mean they are giving 100 % you can bypass one and see what happens to that drill you should be happy with the out come zaper fla

How to connect a Miller welding machine


Do you need information on how to connect the electrodes to use it, or how to connect to your garage/shop/house's power?
If it's a different type of plug than your outlet has the ability to receive, it likely means it's a 220 welder (as most welders are), and you would need a 220 outlet to plug it into. In which case, you need an electrician or someone else capable of wiring and installing a plug for you.
If you're wanting to know how to connect the electrodes to use the welder, the negative (black, generally) clamp needs to be securely clamped to a (preferably bare) metal area near where you want to weld. Usually problems with good ground connections are caused by not having the ground attached to bare, shiny steel. If it arcs at the clamp, it means it's not grounding well enough to work properly.

Tip

Sharpening electrodes when tig welding in DC


Use the smallest tungsten possible, ie 1/16" welds up to 115amps. Hold the tungsten straight up the face of the grinding wheel so the striations go up the tungsten. This encourages the arc to go straight down the electrode thus avoiding arc wonder on lower amperages. It also helps to make the point as long as possible to encourage a finer arc. Happy welding.

I have a miller bobcat 225 is lower power while welding, any idea?


First off, check all of your welding cables to make sure they're in good shape, then check for tight cable connections. Is your machine staying at low idle speed while trying to weld? If so, Switch the idle select into the 'weld' position and make sure the high RPM's initiate. Try welding again. Better? Could be a number of things, if not.

If I turn the ac dc switch while what dose it do to the wielder. Now im not getting any juice to wield .thank you


Changes between AC and DC voltage at the electrodes.



Q: What Type Of Stick Welder Works Best For All-Around Use?

A: A welder with an AC/DC output, whether its an electric arc machine like Miller\'s Thunderbolt or a gas engine drive like Miller\'s Bobcat.

DC welding offers advantages over AC for most Stick applications, including: easier starts; fewer arc outages and sticking; less spatter/better looking welds; easier vertical up and overhead welding; easier to learn "how to weld" and a smoother arc. DC reverse polarity (electrode positive) provides about 10 percent more penetration at a given amperage than AC, while DC straight polarity (electrode negative) welds thinner metals better.

Q: Does An AC Output Have Any Advantages?

A: Yes, if you need to weld on material that\'s become magnetized from friction, such as when hay, feed or water constantly rub against a steel part. A DC output won\'t work because of "arc blow," where the magnetic field blows the molten filler metal out of the weld puddle. Because an AC output alternates between polarities, it enables you to weld magnetized parts.

Miller welder 330a/bp it will not weld in D/C straight or reverse no ark but will work in A/C its like there is very low volts I was welding and then could not strike a ark


It's likely that your pedal is the problem. Pull the cover and check it electrically - these have been problematic in the past. You can further troubleshoot by selecting constant output and test the output.

Miller S-54D 115V digital wire feeder that does not weld right.


Hi Kevin,
Causes of poor penetration: Travel speed too fast, welding current too low,
poor joint design / and or preparation, electrode diameter too large,
wrong type of electrode, excessively long arc length.
Solutions: Decrease travel speed, increase welding current, increase root
opening or decrease rootface, use smaller electrode, use electrode with deeper
penetration characteristics, reduce arc length.

Miller syncrowave 200 makes buzzing noise from spark gaps.


Odd noises other than the normal sound of the spark gap working are often the result of dust and junk inside the case of your welder. That it also bogs down when it gets warmed up (fan comes on), also points to a need for some "annual maintenance" stuff being done.

Completely isolate the machine from the building power supply, pul the plug, open the circuit breaker, do whatever it is that makes the machine have no connection to any power.

Take off the covers with a 10mm or 3/8 inch socket (can't remember which)

Use a shop vac to **** out all of the dust and debris out of the machine. Low pressure (40 psi) air can sometimes be helpful to dislodge caked on dirt. Avoid any metal tools near the capacitor bank inside the welder.

Wipe off the fan blades.

Clean the spark gap electrodes by inserting and removing a matchbook cover, a business card, or a piece of white cardboard several times. Inspect the electrodes and adjust them according to the manual that came with the welder.

Check all of the power wiring connections for tightness by gently tugging on them. Look for signs of overheating on the power connections and on the internal connections to the welding terminals. Check the range switch for heating too.

With the cover still off, reconnect the power and turn the welder on. Look for obviously vibrating laminations on the main input transformer. If you see one buzzing back and forth, or if you notice lots of wear and tear on the varnish coating of the laminations, shut everything down and repair the loose laminations with some anti-fungal high voltage varnish.

Turn the welder off, disconnect the power, and put it all back together. Then turn the power back on and weld something, if htere is still a buzzing noise you'll need a Miller tech to solve the problem, you likely have a bad input transfirmer.

Regards,
Carl
