PONTIG 1880 HF is machine designed for TIG DC welding in argon shield (steel and stainless steel) or coated electrode MMA. Arc ignition can be carried out by the HF ionizer or by friction of the tungsten electrode’s end. Big advantage is a clear and easy to use modern panel with welding current display. Control panel is designed for quick and intuitional change of parameters with a single knob. No need to remember the sequence of settings for a given function, which greatly simplifies the welding operation. The knob is designed to set values (e.g. welding current or current fall time), or to switch between functions and working modes. Display on front panel can show welding current, function values or error code if device’s work is disturbed.

Very modern, ergonomic housing is made of high quality materials. The durability of the housing is reinforced by producer’s patented solution called DDR (Dual Density Reinforcement).

Rubber shields have three basic functions:

• non-slip layer on handle,
• non-slip layer on the sides of the base to increase adhesion to the ground and to protect from accidental fall,
• shock absorbing inside the unit to protect electronic components.

Devices automatically switch to STAND BY mode, if welding does not restart within 15 minutes. It helps to save energy and significantly of some electronic components and reducing the risk of accidental run of the electric arc.

Built-in intelligent ventilation system, which works in case of welding or exceeding specified temperature inside, allows to limit the dust accumulation inside the machine and increases lifetime of rectifiers. Devices are equipped with self-diagnosis system, which shows error codes on the display, in case of their occurrence. 

In case of electrode welding there are HOT START and Ant-Stick functions available. TIG DC welding at pulsing current (PONTIG 2220 HF PRO) allows welding of thin metal sheets without distortion and discoloration thanks to less heat induction into the weld. Working at TIG DC with high frequency pulsing current can be regulated from 10 to 500 Hz.

Equipment is delivered in carton box with a gas and earth cables, without TIG torch.
