4. సెటప్ సూచనలు
Proper setup is crucial for safe and effective welding. Follow these steps to prepare your Handler 140 for operation.
4.1 పవర్ కనెక్షన్
The Handler 140 operates on 115V AC power. Ensure you connect the welder to a properly grounded 115V, 20A circuit.
4.2 వైర్ స్పూల్ ఇన్స్టాలేషన్
- Open the side access door of the welder.
- Install the wire spool onto the spool hub. The Handler 140 supports both 2 lb and 8 lb spools. Use the provided adapter for 8-inch spools if necessary.
- Thread the wire through the drive roll system. Ensure the correct drive roll size is selected for your wire diameter.
- Close the drive roll tension arm. Adjust tension as needed; too much tension can deform the wire, while too little can cause slippage.

4.3 Polarity and Gas Connection
The Handler 140 allows for easy polarity changes, which is necessary when switching between flux-cored and solid wire welding.
- Flux-Cored Wire: Use DCEN (Direct Current Electrode Negative). The MIG gun connects to the negative terminal, and the work clamp to the positive terminal. No shielding gas is required.
- Solid Wire (MIG): Use DCEP (Direct Current Electrode Positive). The MIG gun connects to the positive terminal, and the work clamp to the negative terminal. Shielding gas (e.g., C25 or 100% Argon) is required. Connect the provided dual-gauge regulator to your gas cylinder and then to the gas inlet on the back of the welder.

5. ఆపరేటింగ్ సూచనలు
The Handler 140 features a sloped control panel for easy visibility and adjustment of welding parameters.
5.1 నియంత్రణలు ఓవర్view
- వైర్ ఫీడ్ స్పీడ్ కంట్రోల్: Infinitely adjustable knob (0-100) to control the speed at which the welding wire is fed.
- వాల్యూమ్tage Tap Settings: Five tap settings (1-5) to adjust the welding voltage, allowing for precise control across various material thicknesses.
- Thermal Overload Protection Light: Illuminates if the machine overheats and automatically shuts down to prevent damage. The unit will resume operation once it cools down.
5.2 Welding Guide
The Handler 140 is capable of welding mild steel from 24 gauge up to 1/4 inch, and aluminum and stainless steel from 16 to 11 gauge. Refer to the welding guide chart located inside the wire compartment door for recommended settings based on wire type, material thickness, and shielding gas.
