SOURCE: miller Syncrowave 250 / no tig arc start

seems that you have a ground issue. make sure the ground clap is on barte metela and secured tight. make sure your tungsten electrod is about 1/8 of an inch form the edge of the cone. you will find that you will get a faster arc this way.

How to do conecct arc welding machine bx1-250


The black lead is connected to the metal you are attempting to weld, it has the silver ground clamp connected to it

The remaining red lead with the electrode holder connected to it holds the electrode
These welders are also capable of using 125 & 230 vac, 1-phase current from your mains there is usually a switchable indicator on the machine allowing you to select the input voltage

My tig welder wont arc unless I touch the metal with it


my guess would be the type of welding machine you have.usually there is extra switch which says start control also continious cycle , sometimes smaller machines dont have these switches to allow a wider variety of tweeking the welder ,also its ok if you have to touch the base metal cause thats what starts the contact with the work peice ,keep a arc after touching about 1/4 inch away from work peice ,also a good steady hand rest will make a good welder in any situation this should allow the arc to remaim stable with a comntinious weld arc puddle. happy welding

Arc starter on sync 350 interferes with equipment


It's the high frequency, ground the case of machine, work lead connection and work table, do not chain grounds together, this will cause a ground loop.

Miller welder CP250TS


You don't say why you need schematics. Most of the stuff that you need to know to install, use, and understand the welder is covered in the operator manual. You can get one at this web page.

There is also a copy of the schematic diagram on the inside cover of most Miller welders. Please be careful if you're not familiar with high current power supplies, you could get hurt pretty badly in the blink of an eye.

Regards,
Carl
