Question about Miller Syncrowave 200 Tig Welder Cover 300059 New

Open Question

Miller 250 I have HF but it won't jump to an arc unless I floor the pedal and touch the tung to the steel. When I get an arc, I have to back off real fast before I burn through. When I stop I can start again no problems unless I let the gas cycle stop, then it's the same start-up problem

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.

Your problem is in one of two areas. The controller board inside the unit or a bad trigger on your gun.

The inverter or control of it has failed. Unit will require servicing. If you are not electronically adept, this is NOT DIY. Do your best to check the control pedal wiring, especially connectors and the cord near connectors.

SOURCE: Not getting a starting arc when foot pedal is

Hi:

The foot control has a micro switch in it, this one must be worn out. Take it to your nearest werlder shop (like praxair... www.praxair.com ) and ask for the microswitch by brand and model of your foot control. It's easy to replace. Probably the welder shop must order it, since it's noy pretty common for this switch to go bad, but it happens, specially on old welders.

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.

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
