Miler trailblazer 325 EFI problems and solutions

The following are some common problems that you may experience while using your Miler Trailblazer. But, we have included tips to solve those issues, so you can avoid them as much as possible.

Cracks

The most common complaint against this Miller Trailblazer 325 is that it gets cracks. The situation becomes worse when the welder keeps using the machine with cracks. Doing so makes the creak more profound over time.

Solution

Fixing a cracked welding machine is a complex task. You will need a professional mechanic with adequate knowledge of the function of the welding machine.  The repairman will have to fill in the cracked area using filler metal.

So if you are willing to avoid this difficulty, maintain the proper grinding time based on the mail trailblazer user’s manual.

And don’t exceed the time. Despite this, fit all the machine plates and double-check them to avoid cracks. Finally, don’t overheat the welder and dust and other debris regularly.

Undercutting due to high voltage

Undercutting can occur in any welder for a variety of reasons. If the operator uses a higher voltage than the suggested rating, the welder can cause an undercut. Despite this, using a thicker welding rod or placing it in the wrong position also causes undercutting.

Solution

If you want to avoid an undercut problem on your welder, recheck the amount of weave you are using. Use the compatible welding rod size and don’t use a much bigger one. 

Despite this, place the welding rod in the right position. Another effective tip is to not go faster than recommended and to double-check the speed.

Blocked parts and porosity

Another common Miler Trailblazer 325 EFI problem that welders may face is porosity. It can be caused by corrosion, paint, water, oil, or other welder parts. Even porosity can cause rapid failure in your welder when it requires less gas for shielding.

Solution

You have to follow lots of essential steps to avoid porosity in your welder. Disassemble the welder and clean it, particularly its plates. Plus, make the plates dry completely.

Inspect the welding torch and repair the leaks if you find any. You should also check the condition of the gas nozzle and keep it clean all the time.

Spatter

If some drops of a molten metal approach closer to the welding arc, it can cause a spatter. This problem occurs in milers’ Trailblazer 325 EFI when using the gas metal arc welding method.

Another reason behind this problem is that using a large number of power results in incorrect polarity. Even if you use insufficient gas for shielding, you can experience spatter.

Solution

You can avoid the spatter problem by following a few tricks. Use the recommended current instead of the higher one. Increase the angle of the torch plate to an appropriate angle.

Recheck the arc length before beginning the welding process. Plus, make sure the polarity and gas flow rates are perfect and meet the required values. Clean the gas nozzle to avoid spatter problems.

Machine deformation

Many welders are experiencing deformation when using the Miller Trailblazer 325. It can happen if the welding rod becomes contracted and hardened over time. Other factors responsible are inadequate clamping and incorrect welding sequences.

Solution

If you want to avoid the deformation of your Miller Trailblazer 325 welder, clean its welding rod regularly. Plus, use the recommended welding sequence and change it if you notice the distortion. 

You can also make a few passes throughout the welding process. Finally, stick to the manufacturer’s recommended welding rod and weld all sides.
