The ESAB 186i is a welding machine that is capable of performing TIG and stick welding processes and can weld numerous types of metals and alloys, in addition to materials like non-ferrous alloys stainless, mild steel and chrome alloys.
The welder is used in industries like automotive, transportation, light fabrication, repair/maintenance. The machine has digital meters for displaying voltage and amperage and trigger control.
It is also compatible with a foot pedal and a torch slide control.
The 186i is manufactured by Sweden based company ESAB which founded by 1904. The company develops and produces welding and cutting equipment all over the weld.
The following section will elaborate on the specifications of the welder.
Key Specifications of ESAB 186i Welder
The ESAB 186i is a single-phase constant current welder is capable of performing Stick and TIG welding processes. The welder can weld up to 3/8 inches steel or 3/16 inches aluminum.
The product weighs just over 48 lbs. The product’s maximum amperage output is 200 Amperes.
The welder’s AC square wave frequency can be adjusted when operating on aluminum for optimal performance.
The pulsed TIG feature on the machine also allows the user to reduce heat input when working on thinner material by alternating the weld current.
The 186i also dons a hot start feature which ensures a consistent arc starting. This feature can be used for Stick as well as TIG welding. The welder’s overload protection feature protects the internal electrical components from overheating and further damage.

How to install/setup the ESAB 186i Welder
The 186i just requires the connection of the torch and a gas cylinder for operation.
The connection starts with attaching the ground clamp cable to the positive output terminal, making sure the electrical connection is achieved.
The torch is connected through the negative terminal and an 8-pin socket. The TIG torch gas hose also has to be attached to the gas outlet.
The welder requires Argon for running the TIG process, for which a gas cylinder and regulator have to be installed along with the torch. After the gas and torch are successfully connected the welder is ready to operate.
When the ET 186i AC/DC is used with foot control for current control, the depression of the foot pedal is used for increasing and maximizing the current input. The welder has both AC and DC output so that the user can operate on aluminum as well as other non-ferrous metals.
