Constant currents are used in shield metal arc welding to maintain a preset number of amps in the electrical output. However, gas metal arc welding will use a constant voltage output, since the arc length is not manually adjustable. Transformer welding machines transform high voltage/low current input to a high current/ low voltage output. A lift arc feature allows the operator to weld delicate metals (such as aluminum). By selecting the lift arc setting, the operator is able to lower the frequency output enough to ensure safe welding and repair work around sensitive electrical apparatus. Ensure the ground wire is clamped on to the surface of the work to be welded.
Nozzle tips
Welding machines generate an arc from either a ball end electrode or a fine point. Arcs tend to travel a bit off track with a ball end electrode. To reduce arc wandering, use only the products that include a fine end welding torch. In order to distinguish between a fine end and a ball end electrode, look for machines which have a wire that protrudes from the nozzle of the welding torch (fine end). Ensure the arc is held away from the work piece when arc welding (Some hobby welders require the nozzle to be carefully dragged across the work area like a match [igniting the welder tip]).
Spot welding
Spot welding machines utilize a pair of electrode clamps to permanently join two sheets of metal together. An electric current passes from one electrode to the other electrode. In the process of electrical energy moving between the electrodes, the metal becomes very hot, causing the molecules in the metal to become excited. When the metal cools, the molecules stop moving, resulting in a permanent bond between the two metal sheets.
Dancy welders supply Welding Machine based on up-dated inverter technology.They are in small size,light and portable.
Inverter welder is a type of welding power supply capable of providing a high current for welding. Due to the higher frequency of the output current, Dancy inverter welders produces a smother arc when welding. Adjustments to current and voltage can be made to accommodate differences use in material composition and thickness, giving the welder tighter control over the welding process. It is possible to use an DANCY inverter welder to power all welding processes including Stick, Metal Inert Gas (MIG) and Tugesten Inert Gas (TIG),also Air Plasma Cutter
The reduced size and weight of these welders make Dancy welding machines popular choices used in machinery maintenance facilities and automobile repair shops,welding and fabrication shops. Farmers, as well, are increasingly turning to portable, lightweight units to make on-site repairs.
Dancy welders range from ARC welder ,Tig Welding Machine,Mig and MAG welding machine ,Air Plasma Cutter , Mulit use TIG MAM welding machine,Multi welder with Arc/Tig/Cutter,and Welding Supplies to fit your requirements.
Concerning the demands is various in different country (for example,Russian,Poland,Greece,Brazil,India,Iraq,Vietnam,Colombia.etc),we always produce machines to fit your need.Your consultant or requirement will be answered professionally though our experienced sales people and engineer.
