Setup

Power Connection

The MTS-185 features an intelligent power supply system that automatically detects the input voltage, allowing operation on both 110V and 230V. Use the provided power adapter to connect the machine to the appropriate electrical supply. Ensure the power outlet is properly grounded and capable of handling the welder's current requirements.

Gas Connection (for MIG/TIG)

For MIG and TIG welding, a shielding gas is required. Connect your shielding gas cylinder (e.g., 100% Argon for TIG, Argon/CO2 mix for MIG) to the gas inlet on the rear panel of the welder using the provided air hose. Ensure all connections are secure and leak-free. Adjust the gas flow rate according to the welding process and material.

Wire Installation (for MIG/Flux-Cored)

Open the wire spool compartment. Install the welding wire spool (compatible with 2lb and 10lb spools) onto the spindle. Carefully thread the welding wire through the wire feeder mechanism, ensuring it passes through the correct drive roll groove and the MIG gun liner. Adjust the drive roll tension to prevent slipping or crushing of the wire.

Torch and Clamp Connections

Connect the appropriate welding torch (MIG or TIG) or electrode holder and the work clamp to their respective terminals on the front panel of the welder. Ensure all connections are tight and secure to ensure proper electrical contact and safe operation.

Operating Modes

MIG/Flux-Cored Welding

1. Select the "MIG" mode on the control panel.
2. Adjust the wire feed speed and welding current according to the material thickness, wire type, and desired weld characteristics.
3. For Flux-Cored welding, ensure the correct polarity is set (typically DCEN - electrode negative). For Gas MIG welding, ensure DCEP (electrode positive) and that the shielding gas is flowing.
4. Begin welding, maintaining a consistent travel speed, arc length, and gun angle for optimal results.

Lift TIG Welding

1. Select the "TIG" mode on the control panel.
2. Connect the TIG torch and ensure the pure Argon shielding gas supply is connected and flowing.
3. Install a sharpened tungsten electrode of the appropriate size into the TIG torch collet.
4. Set the welding current. The MTS-185 utilizes Lift TIG arc initiation: briefly touch the tungsten to the workpiece and then lift it slightly to establish the arc.
5. Maintain a short arc length and feed filler rod manually into the weld puddle if required.

Stick (SMAW) Welding

1. Select the "STICK" mode on the control panel.
2. Connect the electrode holder and the work clamp to the appropriate terminals.
3. Insert the correct type and diameter of electrode into the electrode holder.
4. Set the welding current based on the electrode type, diameter, and material thickness.
5. Strike an arc by gently scratching or tapping the electrode on the workpiece. Maintain a consistent arc length and travel speed.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your AmicoElectric MTS-185 welder.

Regular Cleaning

• Periodically clean the machine's exterior with a dry cloth.
• Use clean, dry compressed air to clear dust and debris from the ventilation openings and internal components (if accessible) to prevent overheating.

Consumable Replacement

• MIG: Regularly inspect and replace contact tips and nozzles as they wear out or become clogged.
• TIG: Check and replace collets, collet bodies, and sharpen or replace tungsten electrodes as needed.
• Stick: Ensure electrodes are stored in dry conditions to maintain their integrity.

Cable Inspection

• Regularly inspect all welding cables, torches, and clamps for any signs of damage, cuts, fraying, or loose connections.
• Replace any damaged components immediately to ensure safe and efficient operation.

Troubleshooting

This section provides solutions to common issues you might encounter during operation.

No Power

• Check that the power cord is securely connected to both the welder and the power outlet.
• Verify that the circuit breaker or fuse for the power outlet has not tripped.
• Ensure the main power switch on the rear panel of the welder is in the "ON" position.

Poor Arc Start/Stability

• Ensure the work clamp is securely attached to a clean, bare metal section of the workpiece.
• Verify that the correct welding process (MIG, TIG, or Stick) is selected on the control panel.
• Adjust the welding current and/or wire feed speed to appropriate settings for your material and process.
• Inspect and replace worn or damaged consumables (MIG contact tip, TIG tungsten, or Stick electrode).
• For MIG/TIG, confirm that the shielding gas is flowing at the correct rate and the gas cylinder is not empty.

Wire Feeding Issues (MIG)

• Check that the wire spool is correctly installed and the tension on the spool is not too tight or too loose.
• Inspect the drive rolls for proper size matching the wire diameter and ensure the drive roll tension is correctly set.
• Clean or replace the MIG gun liner if it is clogged or kinked.
• Ensure the contact tip is not clogged with spatter or worn out.
