Heavily loaded welding machine generally extracts electric power from AC power supplies in welding operation.This welding machine generally needs the 15-20A electric current in welding operation.The electric current that can use when therefore, they are welded is limit.And such welding machine needs the cable of heavy power line and/or prolongation to move such electric current.
Because bonding machine 100 ' relies on battery pack B10 that electric power is provided in welding operation, and only just needs AC power supplies when giving batteries charging, so bonding machine 100 ' compares with general welding machine, and the electric current of extraction is littler.In structure of the present invention, be 20% o'clock in duty factor, it is 20% 90+A to the electric current of about 7A to generate duty factor that bonding machine 100 ' extracts about 5A continuously.
By contrast, general bonding machine extracts required whole electric power there from the AC circuit and carries out welding operation.In the standard of North America, general conversion efficiency is that 85% welding machine need extract above the output with supply 90A, 20V of the electric current of 18A.Because the set supply socket capacity of most of North America families is 15A, therefore so with this understanding welding machine can't use, and such welding machine also needs to be connected to a kind of special socket.On the contrary, because by utilizing battery B10 to supply necessary electric power, so welding machine 100 ' can be connected on the socket of common 15A.
And owing to only need so low AC electric current, cable C10 and/or the prolongation cable that is attached on the cable C10 can use specification grade to be at least the cable of 18AWG (U.S. rule) or 16AWG.Those skilled in the art will learn: cable C10 and/or extended line can use has more high standard grade, as the cable of 14AWG, 12AWG or the like.
Those skilled in the art will learn: provide to have 18AWG or more the cable C10 and/or the extended line of high standard grade, the total maximum length of cable (not having closing or not melting cable of the bonding machine that causes owing to voltage drop that cable resistance causes) will be at least 100 feet.Preferably, when use had the cable of 16AWG, 14AWG or 12AWG specification grade, the total maximum length of cable (not having closing or not melting cable of the bonding machine that causes owing to voltage drop that cable resistance causes) was respectively about 192 feet, about 304 feet and about 482 feet.Therefore, provide required electric power, under the situation of not using thick, heavy and expensive prolongation cable, can increase the distance from the welding machine to the power supply greatly by using battery.
In duty factor is the output current that 20% o'clock bonding machine 100 ' has 93A, and its highest spendable output current be about 120A to about 135A, and have the adjustable voltage of about 14V to about 24V.
Those skilled in the art will learn: though battery pack (or a plurality of battery pack) B10 is preferably removable, have non-exchange battery but bonding machine 100 ' can change to, it can charge by the charging circuit such as charger 150 on the plate.
Those skilled in the art will learn: among all embodiment of Lun Shuing, discharge control is provided can for different battery pack here.And such discharge control can provide in the outside of battery pack, also can not be used for to wireless bonding machine power supply so that do not have the battery of discharge control.
Though diagram and described embodiments of the invention, the foregoing description also can not diagram and describe all possible form of the present invention.On the contrary, the word segment in the specification be descriptive literal and be not be the restriction, what it will be appreciated that is that under the situation that does not deviate from the spirit and scope of the present invention, the present invention can have multiple different variation.
