DC Inverters Welding Machine Advantages and Disadvantages
DC Inverters Welding Machine Advantages and Disadvantages
DC Inverters welding machine are the sensible buy for amateur arc welding user. If buy cheapest DC Inverters welding machines tend to weld very nicely but the effect is normally that welding component don't last very well.
DC Inverters Welding Machine Advantages:
- DC Inverters Welding Machine is very lightweight, small, and very portable. DC Inverters Welding Machine generally have weight less than 10kg.
- DC Inverters Welding Machine is very efficient - DC Inverters Welding Machine can run up to 140 amps on a 13 amp 240V supply, and tend to have have nice duty cycles (welder can weld for longer on higher settings).
- Most DC Inverters Welding Machine have features such as a soft finish to reduce the crater at the end of a weld, and hot starting to improve the ease of starting.

- DC output results in easy arc starting
- Most DC Inverters Welding Machine can be used for scratch start TIG/tungsten inert gas. More expensive ones tend to have HF (high frequency) start functions for TIG/tungsten inert gas welding.
- All but the cheapest of DC Inverters Welding Machine have 70V or 80V OCV (open circuit voltage)
- DC Inverters Welding Machine pricier ones have features such as "arc force" which adjusts the welding voltage on the fly to cope with dirty plate materials.
DC Inverters Welding Machine Disadvantages:
DC Inverters Welding Machine are complex electronically, and repairs/maintenance can be very expensive. The cheaper DC Inverters Welding Machine are sensitive to knocks and spikes in input voltage. The more expensive DC Inverters Welding Machine have more protection - some DC Inverters Welding Machine are designed to withstand being dropped from 0.5m.

Nice blogpost and thanks for sharing such useful information about Steelmax. If you are interested for the Steelmax tools then you should visit atWelding Automation .I just try this and its working is awesome.
TIG Welders has become extremely popular and more companies are choosing to use them instead of other types of welding equipment. Source to know about best tig welders.
