Product Overview
The Extol Premium 160A Inverter Welder utilizes advanced pulse width modulation (PWM) and insulated gate bipolar transistor (IGBT) technology. This design replaces traditional heavy transformers with a compact, portable, and energy-efficient unit. It is designed for high-performance TIG and MMA welding across various materials, including stainless steel, carbon steel, and alloys.
Safety Precautions
Electric shock can be fatal. Always wear dry, hole-free gloves and protective clothing. Ensure the machine is properly grounded. Keep the work area free of flammable materials and ensure adequate ventilation to prevent the buildup of toxic fumes and gases. Protect your eyes from arc rays using a shield with the appropriate filter. Never touch electrical parts while the machine is powered on.
Installation and Setup
Ensure the power supply matches the machine's requirements. Connect the work cable as close to the welding area as possible to ensure a good electrical connection. For TIG welding, connect the gas cylinder, torch, and control cables according to the provided diagrams. Ensure the machine is placed on a stable surface and is not obstructed to allow for proper cooling.
Operation
The control panel allows for precise adjustment of welding parameters such as pre-flow time, starting current, upslope/downslope time, welding current, and pulse frequency. Users can select between MMA, 2T, and 4T welding modes. The machine features intelligent protection against over-voltage, under-voltage, over-current, and over-heating.


Maintenance and Troubleshooting
Regular maintenance is essential for longevity. Perform daily checks on cables, switches, and the display. Monthly, use compressed air to clear dust from the internal components. If the machine fails to operate, consult the troubleshooting guide to identify issues such as power supply problems, gas flow errors, or arc ignition failures. Always disconnect the power and wait for capacitors to discharge before performing internal maintenance.
