Question about Welding Tools

Lastek superstar 300 heavy duty welding machine has only a little arc and does not weld

I checked the supply and the coils and they are working alright. I think the problem is some where in the rectifier.

SOURCE: My welding machine will not weld?

Hi, put the setting on 150 amps, and see if the welder welds. do you have a gas or electric welder?
some welders have a reset botton in front. tell me how many amps your welder produces.

If this doesn’t work for you please write back. Thanks,

SOURCE: Ground lead arcs when I connect, and auto idle kicks up

Hi
what are you connecting the ground lead to?

Is the welding machine phisicaly in contact to what you are welding ?

Can you electrically insulate the welding machine from everything, say stand it on a sheet of timber?

Regards
Rob

SOURCE: Welding machine stops working after a few minutes of welding.

there is probley nothing wrong its called duty cycle.which means that if you are welding long periods or welding at max amps the welder will kickout to cool down.Look on your unit for the tag that tells imformation about your unit.It will show something like 30% duty cycle so that means you can weld 3 minutes at full power before the unit shuts down.

Stud welding makes more sense. Our stud welder systems each have a stud gun welder that spot-welds a series of pins onto the surface of the dented metal.

Is the mishto an ok welder for the hobbiest


There are several models and they look nice, they are not heavy duty units. They can weld up to 1/4 inch or about 5 mm. The thing you want to look for is duty cycle. That machine has 60% duty cycle at 160 AMPS. That means you can weld for 6 minutes at 160 Amps before you have to let the machine cool off.

Craftsman 100ac infinant amp arc welder just stopped working ....the fan still runs. anybody know what's wrong with it????


probably over heated and blew the reset button
100 amp welders have a duty cycle ( time in actual welding use ) of less than 20%
that means for welding for five minutes you have to let it cool down for 20 minutes
the lower the amps the longer you can weld for
beware tat the total amperage of the welder does not mean that you can weld for a long time at that amperage
on the plate on the welder is the duty cycle and you have to be aware of it or the machine will shut down

I have a mishto 220 mig tig mma I can get the arc to work fine but the mig there's no arc at all the machine sounds like its welding but no arc at the gun I'm using gassless wire I thought it may be an...


They told me at welding school the mig transformer has a different slope (whatever that means?) to the tig and mma transformer so I am a little surprised at your question. The implication is two transformer are needed for the three types of welding and for tig and mig a dc converter and also for dc mma welding.

From your description it seems as though welding current is not arriving at the tip of the mig torch or the current is arriving in the wrong form.
You say the mma is fine but you didn't say whether it is fine on ac welding, dc welding or both. I have not tried mig welding with ac and have no idea whether it would be successful but I imagine a lot of sparks and not much welding. The problem could be the rectifier unit is either not working or is switched out of the circuit.

Polarity is important too with dc tig and mig welding.

I hope this provides food for thought.

Lincoln electric ac/dc arc welder will not arc


Check the dial indicator. Sometimes if someone changes the amps while welding, there will be a break in the coil. It will work at a different setting as long as you are away from the break.

I have a dayton model 3z744. got it at garage sale .no ground on it. were do i hook a ground to it inside?


An arc welder is a very simple transformer, Inside it you will find there are two sets of windings, a lighter one and a very heavy one, the lighter one is the primary which works off your home mains and the heavy winding is the secondary that supplies your welding current. The secondary winding has several taps for different currents - these go to the connection for the 'torch' the end of the winding is the ground tap and would usually appear to come from the bottom or the beginning of the secondary coil.
Hope this makes sense to you. If not, come back to me and we can try work it out.

My miller matic 35 welds and stops after about 2 inches let cool for about 30 to 40 sec and it welds again. fan runs


these need a good power supply , i looked and did not see the duty cycle on this welder if you are doing heavy welding 100% power it will need 30- 40 minutes to cool of to weld again. it all depends on the units duty cycle, stated on the welder spec plate ..can you bypass the auto feed speed mode ? this might be the issue.. good luck ..use all the protection you can when welding these are like the sun and can and will burn exposed skin and eyes .. if'n i was any help throw me a bone and vote thanks jay
