PATON StandardTIG 250 digital inverter welder is optimised for TIG (HF) inert gas shielded arc welding, manual submerged electrode arc welding (MMA) and semi-automatic MIG/MAG arc welding (as a source with external feeder) with direct current. Each of the methods mentioned above allows us to use pulsed current (PULSE function). The StandardTIG 250 features a 64% duty cycle and a 3-year warranty.

Straight answers to the questions people ask most when choosing and using single phase TIG welders.
The supply limits the maximum welding current. A standard 13 amp socket gives less power than a dedicated higher-rated supply, so the output you can use continuously may be lower than the machine's maximum. Check the data plate for the input current at full output, and what protection it needs.For higher currents or heavier duty, a dedicated circuit installed by a competent electrician may be needed. Do not assume a plug-in connection will suit full output.
DC machines weld steel, stainless steel, copper and other metals except aluminium. AC/DC machines add alternating current, which breaks up the oxide layer on aluminium and magnesium, so they are needed for those metals.If you will weld aluminium at all, choose AC/DC. If you only weld steel, stainless and similar metals, DC is simpler and more economical. AC/DC machines normally also offer controls for balance and frequency, to fine-tune the arc.
A multi-voltage machine adapts to different supplies, for example running on both 110 and 230 volts, and sometimes wider ranges. This suits people who move between site and workshop or use different supplies.The output you get depends on the supply connected, with less at lower voltages. Check the specification at each voltage, and make sure the plug, cable and protection match the supply you connect to.
Pulse TIG alternates between a higher peak current and a lower background current many times a second. This gives better heat control on thin material, reduces distortion and burn-through, and helps on out-of-position welds and where you want a consistent bead appearance.It is not necessary for every job, but it is valuable for thin stainless, tube and precision work. Check that the pulse settings, range and frequency suit what you intend to weld.
