AC DC tig welder

Curious about an ac dc tig welder?

I have used several tig welders but on this page, I am strictly speaking about the ck mt200 ac dc tig welder.

I have done at least 20 videos and projects using my mt200 welder...both Aluminum and Steel... including a few stick welding videos with 7018 rods.

I often get the question..what is the best tig welder for the money?

And while my answer is usually "It depends"....

There are 5 main reasons why this little ac dc tig welder is a great choice for a lot of folks.

  1. low 5 amp arc start ( most 200 amp tig welders have 10 amp or higher)
  2. true fan on demand ( no unecessary background noise while not welding)
  3. performs better on 115 volt power than most other ac dc tig welders. (140 amps DC on 115v power is no joke)
  4. Foot pedal and tig torch are top notch (ck air cooled torch with superflex cables and high quality foot pedal)
  5. CK worldwide has great customer support and will take care of any potential issues. ( the very few issues I have seen have been taken care of quickly by CK)

OK lets go over these 5 reasons in more detail.

Low 5 amp arc starts

Occasionally, you might need to weld something really thin.

...or do a build up bead on the edge of something really thin.

A 5 amp start comes in klutch for that.

Some 200 amp tig welders list a 20 amp start and while that is not a problem on some jobs, it can melt an edge or blow a hole quickly on really thin metal.

You dont always need a 5 amp start but when you need it,,,you need it.

True Fan on Demand

This is a bigger deal than you might first realize.

Some welders advertise fan on demand but once you strike the first arc, the fans come on and run constantly until you turn the welder off.

that is not true fan on demand.

True fan on demand is controlled by the temperature of the machine and the fans only run when needed to keep the machine under a certain temerature.

Not hearing tons of background noise from constantly running cooling fans is pretty great.

when I use a welder with loud fans, I wear ear plugs...but it still wears on me.


115 volt performance

I made several videos using the mt200 where I only had access to 115 volt power.

Not all tig welders do well on 115 volt power.

Some machines will kick a 20 amp breaker.

I used the mt200 at 140 amps on a 4130 chromoly cluster video pumping the foot pedal to 140 amps and never tripped the breaker.

this is especially a big deal for portable jobs where 115 volt power is the only option without bringing your own generator.

Foot pedal and tig torch

2 of the biggest complaints on 200 amp ac dc tig welders are the foot pedal and the tig torch.

Some companies cut corners here and its a mistake.

The mt200 comes with a nice CK air cooled tig torch with flex head and super flex cables along with a smooth high quality foot pedal.

CK customer support

I saved the best  for last.

My mt200 has been bulletproof for goin on 5 years and I have seen very few issues over the last few years of selling them.

Without exception, CK has taken care of every issue to make sure the customer is happy. CK is a top notch company.
