-
Machine is connected to mains power.
-
Ground clamp is connected to the table or workpiece and its cable is connected to the ground clamp terminal on the machine (negative terminal).
-
The electrode holder’s cable is connected to the torch terminal on the machine (positive terminal).
-
Set the machine to the proper setting.
-
Install the electrode into the holder.
-
-
-
Ensure that all leads and cables are connected properly and are not frayed (power, ground, electrode holder).
-
If leads are frayed, do not weld. Tell a lab manager.
-
Check the area for any flammable materials.
-
Confirm that your material is safe to weld (galvanized steel, for example, is not safe to weld).
-
Know where the nearest fire extinguisher is and the types of extinguishes you will need (Type C for Live Electrical, Type D for Metals, Type ABC for Common Combustibles).
-
Ensure that all safety equipment is in good condition.
-
Position and turn on fume extractor.
-
-
-
Set POLARITY to DC.
-
Set PROCESS to STICK.
-
Set OUTPUT to ON.
-
The AMPERAGE should be set according to material thickness.
-
-
-
Wear closed toed shoes (preferably without mesh), and long pants. Clothing, including socks and shoes, should be a relatively tough fabric that does NOT melt. Cotton, Kevlar, and leather are some good examples.
-
Wear a welding jacket that fits (welder takes priority).
-
Wear heavy duty welding gloves that fit (welder takes priority).
-
Wear eye protection.
-
Wear a welding helmet (adjust sensitivity, delay, and size to comfort).
-
Make sure that the yellow curtains are COMPLETELY closed.
-
MAKE SURE THAT YOU ARE COMFORTABLE.
-
-
-
Appropriately clean the workpiece before starting.
-
One of the primary benefits of stick welding is that it does not require particularly clean material, however, cleaner material will yield a better weld.
-
Clamp material and ensure that it is making sufficient contact with the bench in order to ground properly and not move.
-
In some cases, it may be more convenient to clamp directly to the workpiece.
-
-
-
Turn the power switch on (located at the back of the machine).
-
Configure proper stick welding settings (see step 3 of this guide).
-
To learn more about weld settings and the machine controls, refer to the Miller Dynasty 210 user manual. These pages are attached below. You will be expected to know the controls and settings and what their purposes and application are!

-
Practice the motion of striking an arc and moving the electrode at a smooth pace.
-
Remember that the electrode is consumable and, therefore, must be fed toward the weld piece.
-
The electrode should typically be dragged at an angle not exceeding 20° from the normal axis. Pushing the electrode should typically be avoided.
-
Do not “dip” or “hop” with the electrode. The electrode should stay at a consistent height above the metal(roughly ⅛”). This ensures proper cleaning, heat, and shielding. A rule of thumb is to listen for a consistent frying-like sound. A fluttering sound generally indicates a bad arc.
-
If the electrode becomes stuck to the workpiece, quickly try to break it off. As an alternative to breaking the electrode off of the workpiece, you can easily unclamp the electrode holder from the electrode. Either option should be done quickly.
-
-
-
Understand that the longer you weld a piece of metal, the hotter the metal becomes.
-
Since the electrode holder has a constant power supply, ensure that the electrode does not unintentionally complete the circuit. The machine can be placed on standby to avoid this issue.

We encourage you to watch these videos before practicing:
