Merkle LiteTIG/MobiTIG

Portable TIG welding machines - DC TIG welding!

The LiteTIG 190 DC, MobiTIG 194 DC mobile and MobiTIG 304 DC welding machines are designed for DC (direct current) TIG welding with shielding gas and MMA welding. Each machine offers a wide range of features.

• Stepless adjustment of the welding current.
• Lightweight and portable.
• 2-step/4-step operation.
• High-frequency (HF) and LiftTIG ignition.
• Remote control connector.
• Digital display for all parameters, with preset display and hold function for the welding current.

• Welding programmes (MobiTIG).
• 2 welding currents, activated at the welding torch.
• TIG pulse function as standard.
• Adjustable start/end current and slope time.

Features

High-frequency DC pulse

The MobiTIG and LogiTIG series machines come with high-frequency DC pulse as standard. The arc can be pulsed at frequencies of up to 12 kHz. The arc characteristics offer outstanding possibilities for TIG DC welding that cannot be achieved with a conventional TIG arc:

• Extreme arc constriction.
• Arc similar to plasma welding.
• Lower heat input.
• Higher welding speed.
• Extremely stable arc.
• Perfect for fillet welds.
• Low noise emissions.

Safe transport:

The control panel is fully protected by a sturdy cover. All controls are clearly arranged and ensure easy operation. Extra protection is provided by the Protec rubber edge protection system.

Portable TIG welding units. Perfect handling and functionality!

TCG torch connector:

The main advantages of the Merkle TCG (TIG Center Gas) connector:

• Compact size
• Low weight
• Tool-free torch replacement
• Negative socket for connecting the TIG torch and electrode cable
• 2 rubber rings ensure a gas-tight seal

MMA welding:

• 1. Arc force: Increases the welding current to prevent the electrode from sticking.
• 2. Hotstart function: Increases the starting current to ensure reliable ignition. The hotstart current and duration are adjustable.
• 3. Anti Stick function: If the electrode sticks, the current is switched off immediately. Reignition after separation is possible only after a short delay.

WK 200/230/300 water cooling units

The water cooling units can be fitted as an option to MobiTIG 280 DC, LogiTIG and TIG 300 DC welding units. The welding machine and water cooling unit form a compact, easily transportable unit. Different applications are possible: welding with a water-cooled torch in the workshop or with a gas-cooled torch on site. Simple fitting and removal in seconds, using a plug-in electrical connection (optional) on the rear panel of the unit.
