Quick Setup
Instructions
Power plug wiring:
For either 110 or 220VAC, the GREEN wire is the ground wire. The WHITE and BLACK wires are hot wires.
For Plasma Cutting:
1. Wear a Lotos auto darkening plasma cutting helmet
(Figure 1.1, not included in the box. To purchase, please go to our website.) to protect your eyes from harmful plasma cutting arc radiation and safety gloves to protect your hands during welding.
Figure 1.1
2. Connect the machine gas inlet (on the back of the machine, Figure 1.2) with an air compressor
(Figure 1.3) and set the air pressure to 65-70 PSI. (The Air Regulator is optional if your air compressor has the capability to control output air pressure.)

3. Connect your plasma cutting torch and ground cable to the front panel of the machine. Make sure the ground cable is connected on the right hand side where the “+” sign is located. (Figure 1.4)
- Set TIG Weld /Stick Weld /Plasma Cut switch to Plasma Cut mode. - Set “2.5S/5S” to “2.5S” Mode.
- Set “Machine/PEDAL” to “Machine” Mode. - Adjust Current Dial between 10 and 50 amps.

4.Attach the ground clamp to the metal you want to cut. Grind the metal to make sure the clamp is securely attached to the work piece. Press the trigger of the torch and make sure the air is flowing. Finally, move the torch head to the work piece and start cutting.
5.Change your consumables (tip, electrode, ring, and cup) if they are worn out. The consumables’ type is LCON. If you want to cut the perfect circle or perfect straight line, order a Lotos
LCK roller guider compass kits from our website www.uwelding.com.
For TIG Welding:
1.Wear our auto darkening helmet and gloves to protect your eyes and hands from any harmful welding arc. (Please see step 1 in Plasma Cutting.)
2.Connect the machine gas inlet (on the back of the machine, Figure 1.5) to the argon regulator and adjust the knob to set gas pressure between 15 and 20 min/L (an argon regulator is necessary, Figure 1.6.)
