Question about Miller Welding Equipment

When trying to do spot welds, does not stop

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

the obvious, yet sometimes overlooked problem is to check if the wire feeder you have the proper tension set?(did you do the wire test when you shot the wire to see if it bends or stops)

GW450001AC Where can I find a manual? Where can I find the locking connectors on the welding machinge for the welding cables? Are they called small Dintz? Will this machine run 1/8 welding rod?

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

I see spots after welding. I dont think the helmet darkens as fast as it used to. I stick weld. Can the battey cause this? Not sure where the welding switch should be. I have it to tig and just leave it...

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.

Sir, we are using machine mounted MIG welding torches.Before these torches are working properly, now we got problem i.e, nozzle became red hot, cos of this we had stopped our production. pls suggest me.The...

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.

Good luck

Century 155gs wont weld correctly

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.

Welder skips when welding

Hello there
here are some easy steps to see if these will help you ok
best regards michael
  1. 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.
  2. Step 2 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.
  3. Step 3 Clean 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.
  4. Step 4 Inspect 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.
  5. Step 5 Examine the welding cable for worn spots. A badly worn cable can cause problems.
  6. Step 6 Adjust the brake on the wire spool. Setting it too high or too low can cause problems with your machine operation.

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.
