A MIG short arc-welding machine with a 60 per cent duty cycle at 150amp is now being marketed by Suffolk Iron Foundry (1920) Ltd. Called the SIF Gasmatic 150, it has the advantage of being easy to use for automatic purposes.
The machine has automatic inductance, which allows 0.8mm, 0.9rrim, and 1mm wires under CO, and gas mixtures to be used with minimum control resetting.
Another feature is that the machine comes with a separate wire feeder which is portable and can be placed up to 80ft from the power source. The speed control of the wire feeder has been constructed with solid state components to give a long life, peak performance and minimum maintenance. No warm-up time is necessary and the feedback circuit gives constant torque even at low speeds. The heavy-duty motor is a 42V unit and its use promotes safety.
A lightweight, air-cooled welding gun, supplied with the machine, is particularly suited for out-of-position welding. Its 60deg curved head has double-steel insulation and provides goad visibility and easy access to confined locations. A choice of nozzles for different purposes is available.
