Inverter welder MMA 200A PFC with power factor correction module, advanced functions, and DC TIG LIFT welding option with pulse. The PFC module reduces disturbances emitted to the network and lowers reactive energy consumption. As a result, we minimize the risk of welding repairs in places with sensitive electronics, and we also utilize the full potential of the welder (maximum amperage) even with a 50-meter extension cord. Suitable for rutile, cellulose, and basic electrodes.

PFC module:
Reduces energy consumption, limits current harmonics. YT-81358 at the maximum setting of 200A will consume 7.1 kVA. A welder with the same welding current but without the PFC module will consume around 9.9 kVA. Nearly 3 kVA more at a supply voltage of 230V is a huge problem for both the electrical installation and power generators. In many cases, the maximum welder amperage will not be achievable due to the operation of overcurrent protection in installations, high voltage drop (especially for installations with cable cross-sections smaller than 4mm2), or the suppression of the power generator.

Function description:
DC pulse - welding with pulsating current. The welding current reaches alternately a base and peak level in an orderly manner. This reduces the overall heat flow to the welded material and splatter. It facilitates welding of metals with high thermal conductivity, as well as thinner metals without burning holes. Additionally, narrower and deeper welds can be obtained on thicker metals. Model YT-81358 has pulse frequency adjustment in the range of 1 to 100Hz and peak and base current power values relative to the algorithm for a given setting in the range of 10 to 50%.
Hot start - when the electrode is applied to the welded material, the welder briefly increases the welding current, significantly facilitating arc ignition. Model YT-81358 allows adjustment of the function in the range of 0-50% and the duration of its operation from 0.0 to 2.0s.
Arc force - adjusts the arc dynamics depending on the distance of the electrode from the welded element. Model YT-81358 has parameter adjustment for this function in the range of -15 to +15%.
Anti stick - cuts off the welding current when the electrode sticks, allowing the electrode to be detached from the welded material.
VRD - the function reduces the idle voltage from around 60V to a safe level for humans. Model YT-81358 has the ability to turn the VRD function on and off.
Electrode modes - automatic adjustment of the output voltage for different types of electrodes. Model YT-81358 has dedicated settings for basic (E7018), cellulose (E6010), and rutile (E6013) electrodes.
Overheating protection (fan on demand) - the microprocessor in YT-81358 monitors the temperature of critical components in real time. Depending on the temperature, it activates and controls the fan speed.
