Frequently Asked Questions - DN-120T Vevor
How to install the Vevor DN-120T welding machine?
Place the machine on a stable, dry surface. Plug it into a 230 V grounded outlet. Connect the ground cable to the workpiece and the torch cable to the positive terminal. Ensure the welding wire is properly engaged in the drive roller before starting.
What type of wire to use with the DN-120T?
Use a solid welding wire of diameter 0.6 mm or 0.8 mm, suitable for steel. For gasless welding, you can use a flux-cored wire of the same diameter. Check compatibility with your model.
How to adjust the welding wire speed?
The wire speed is adjusted using the knob on the front panel. Start with an average value, then adjust according to the bead appearance. Too high a speed causes spatter, too low a speed makes the arc unstable.
Why does my weld have spatter?
Spatter is often due to too high wire speed, too high current, or a dirty nozzle. Clean the nozzle regularly, reduce the wire speed, and check that the nozzle-to-workpiece distance is correct (about 8 to 12 mm).
How to maintain the nozzle and consumables?
After each use, let the machine cool down, then remove the nozzle and contact tip with pliers. Clean the welding residue with a wire brush. Replace worn parts to ensure a stable arc.
Can you weld stainless steel with this machine?
Yes, the DN-120T can weld stainless steel using a suitable stainless wire (308L for example) and argon/CO2 gas or a specific mixture. The maximum power of 120 A is suitable for thin sheets.
What to do if the device overheats?
The device has thermal protection that automatically cuts off the circuit in case of overheating. Wait for the fan to cool the machine (about 10 to 15 minutes) before resuming work. Reduce the duty cycle or the current if the problem persists.
What is the maximum power consumption?
At full power, the machine consumes about 4,000 W (4 kW). Use a 230 V outlet with an appropriate fuse (minimum 20 A) to avoid unexpected tripping.
How to change the welding wire spool?
Open the side compartment, unscrew the spool retaining screw, replace it with a new 5 kg spool. Thread the wire into the wire guide, then into the drive roller while loosening the pressure. Readjust the pressure for proper feeding.
Is it possible to weld without gas with this machine?
Yes, by using a flux-cored wire (wire spool with flux). In this case, make sure the polarity is correct (usually the torch on the negative terminal) and remove the gas hose. Consult the manual for the recommended polarity.
