Here at HTP America®/USAWeld® we offer a variety of both inverter-based and transformer-based MIG welders.
Our inverter MIG welders, which feature electronic adjustments controlled by a microprocessor, allow you to achieve excellent welding quality thanks to the advanced technologies applied. The microprocessor circuit controls and optimizes arc transfer irrespective of the load variation and of the impedance of the welding cables. The inverter technology used in our welding machines enabled us to obtain the following:
♦ Machines with extremely low weights and compact dimensions ♦ Reduced energy consumption ♦ Excellent dynamic response ♦ Very high power factor and yields ♦ Better welding characteristics ♦ Ease of use
The sensitive components used in our inverter MIG welders are cooled with forced air by fans with low noise production, and our inverter MIG welders also feature sophisticated, electronic overheat protections to prevent damage to your machine.
Our transformer-based MIG welders (the MIG 200 and the MIG 2400) offer the following features:
♦ Control Transformer—Provides low voltage to run the printed circuit board, the wire drive motor, and the main relay. While many companies take this voltage from the main welding transformer, shortening the life of the transformer and not providing as stable a voltage supply, our machines come standard with this separate transformer. ♦ Printed Circuit Board—Our solid-state printed circuit board can be removed and installed in seconds, without any tools, for easy, do-it-yourself service. ♦ Main Relay Mechanism—One of the main reasons you will fall in love with your MIG welder from HTP. Imagine touching the welding wire exactly where you want to start welding, pulling the trigger, and starting the weld right there in that exact spot. With a main relay, the wire is not electrically hot until you pull the trigger. ♦ Copper Wound Main Transformer—As we all know, copper conducts electricity better than aluminum and lasts a lot longer. Copper, most importantly, however, provides a smooth, stable arc. ♦ Circuit Breaker Protection—We use circuit breakers on the primary input side of the welding machine, which helps protect the internal components from damage. ♦ Thermoswitch Protection—In the unlikely event that you exceed the duty-cycle of your welding machine, the thermoswitch shuts the machine down, protecting the internal components from overheating.
