Features
Welding modes
You have three modes: TIG DC, TIG DC PULSE and MMA. TIG DC and TIG DC PULSE weld stainless steel, carbon and low-alloy steels, copper and titanium, under inert shielding gas. With the pulse parameters you influence the weld shape and how focused the arc is. Pulse reduces the heat that goes into the material, which helps with thin parts.
Arc ignition and torch button
You strike the arc without contact (HF) or by touch (LIFT). LIFT is used where electromagnetic interference can affect the surroundings. With both methods you choose how the torch button works: 2T or 4T (button latch for long welds).
Panel and display
On the digital display you set pre-gas, start current, current up-slope time, welding current, base current, current down-slope time, end current, post-gas, pulse width and frequency, intermittent welding length, and HOT START and ARC FORCE.
MMA functions and VRD
ARC FORCE (short-circuit current adjustment) helps droplets transfer from the electrode to the weld pool and stops the arc going out when a droplet touches it. HOT START (hot start adjustment) gives a higher current at each strike, so the electrode ignites more easily. ANTI STICK cuts the welding voltage when the electrode sticks to the material, so it is easier to pull free and no accidental arc forms. VRD (Voltage Reduction Device) lowers the open-circuit voltage at the electrode to a safe value and protects you from electric shock when you work in damp surroundings.
Cooling and protection
A fan cools the machine, and it has overload protection. Quick gas coupling: you connect and disconnect the torch without tools.
