LORCH TIG Up-Down Torch - Water-cooled 8 m LTW 1800-UD

Welding TIG
Lorch TIG torches for optimum work results:
- Highly fl exible hose pack;
- Ergonomically shaped torch handle recess;
- Otimum handling in all positions;
- Low weight, robust design, long service life;
- High durability.In the TIG (Tungsten-Inert-Gas) process, the electric arc is formed between the non-fusible tungsten electrode and the part to be welded. The bow is very intense and can be guided perfectly. A separately fed argon protective gas protects the arc and solder zone against atmospheric access. If necessary, additional material is added manually or with a special cold wire feed.Steel, stainless steel, copper, titanium and others are welded with direct current. The electrode is connected to the negative poleand rectified in the ground. Aluminum, magnesium and its alloys are exclusively welded with alternating current to tear the oxide layer. Then the electrode is blunt. The welding generates a round to spherical shape. With modern sources of current by inverter can also be welded
