When trying to do quick spot welds, my machine seems to not shut down the welding action, as reradily as it did, when first bought. It seem to continue for a second or so after the trigger is released. I have a miller 210 that I bought a little over a year ago.
It is one of two things. (1) the spot timer my need to be cleaned or re-placed.(2) ckeck and clean the ground clamp and ground wire hook-up. you can clean the the timer by blowing it out with compressed air or nitrogen

Try to find the manual from your local tool trader, or go to the manufactures website and give them the serial # and and you can print a manual. I've done it with heavy equipment. To buy the quick connects, just look up welding supply in the yellow pages. Always buy your welding tools and supplies from a lisceansed welding supply. And yes you can weld with 1/8th rod, but you have to turn it up to 140 to do so, and use a 7018 rod
Hi there, Tig is very brite.If your seeing spots I would try another hood for awhile.If the battery is to weak or you can't adjust up to shade 12 for tig it can be very hard on your eyes.I would try a regular hood on some scrap and see how that works.I couldn't change the battery in my hood so I just had to buy another one.One other thing check for leaks in your hood.You've already done that more than likely. Do you need a cheater lens?
Ensure that you are using the correct contact tip in the welding gun, if the tip is too short; the cup will fill with splatter and submit excess heat to the cup.
Also, make sure if you are using a name brand gun 'miller, lincoln etc' to use THEIR contact tips, the miller guns use a special tip 'the threads on the tip are mashed into the gun ensuring maximum contact for high amperage welding' if the wrong tip is used, it will overheat and jam the wire.
Another thing to remember is to check the amperage rating on the actual gun itself; you may have a 150 amp maximum gun on a 300 amp welding unit.
Hi, Have you tried replacing your liner? The liner can get worn in the gooseneck. As the wire wears into the liner it creates a groove. The wire has +/- tolerances, and when it gets to the high side, it can cause the wire to catch in the smaller size groove, this will cause a studder effect. You can check your drive roll tension as well. The gun will run better with the cable extended, not looped in circles as is often seen. As you mentioned it has been doing this from the start, check the liner size against the wire size you are using. You may need a larger liner. I have found that a very high percentage of feedability issues come from incorrectly cut/sized/maintained liners. good luck.
Hello there here are some easy steps to see if these will help you ok best regards michael
See if the wire is feeding properly. A worn drive roller can
affect the feed and cause it to slip. When you're checking, look for
debris and dirt on the liner. This can also cause bird nesting.
Sometimes troubleshooting welding machines is as simple as cleaning it
and allowing the wire to move freely.
Look at the tip near the wire exit, inside of the gun. A worn out tip doesn't allow the electricity to efficiently hit and creates a lot more work on the job. Burn back can cause a bad wire.
the welding cup of the splatter. This task seems mundane, but
troubleshooting welding machines usually involves clean components.
Proper gas coverage cannot occur if the cup is plugged.
the ground clamp. When this part is coated with oxides, electrons can't
readily transfer. A bad ground **** can cause a lot of resistance and
change the way that the current comes back to the machine.
Examine the welding cable for worn spots. A badly worn cable can cause problems.
Adjust the brake on the wire spool. Setting it too high or too low can cause problems with your machine operation.
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.
