Main Features
■ A digital controlled welding machine,adopting inverter soft switch technology
■ The latest technology IGBTmodules and rectifier diodes are used on the machine,with good reliability
■ With excellent MMAwelding function,the hot start current and arc force current can be adjusted separately
■ Accurate welding control,with excellent arc striking
■ Lighter weight,smaller size and more user-friendly design,easy to operate
■ With automatic protection function of over-heating
■ All the welding parameters can be preset,stored and called out,with 2 step and 4 step functionselection
Product Application
■ It's mainly used for welding carbon steel,stainless steel,copper and its alloy,heat resistant steel,titanium alloy,etc
■ It is widely used in electric power construction,chemical construction,oil
field construction and heavy industry which requires frequent moving in bad environment
