Abstract
A welder having an integrated gas cylinder is disclosed. The welder has a power source constructed to condition and output an electrical signal suitable to welding and a gas cylinder disposed in an enclosure.
Claims32
A welding-type apparatus comprising:
- an enclosure having a carrying handle and sized to be portable;
- a power source having an inverter and constructed to condition and output an electrical signal suitable to welding and located in the enclosure;
- and
- a gas cylinder disposed within the enclosure and constructed to deliver shielding gas from the gas cylinder upon connection of the gas cylinder to the welding-type apparatus.
1 more element
A welder comprising:
- a power source configured to generate welding-type power;
- a welding gun in electrical communication with the power source;
- a first gas path;
- a gas cylinder disposed within the power source and connected to the first gas path and constructed to supply gas to the welding gun;
- and
- a second gas path extending from the power source and connectable to gas container located remotely from the power source.
3 more elements
A method of constructing a welding-type apparatus:
- positioning an inverter based-power source with respect to a base;
- providing a restraining system to support a gas cylinder by a body of the gas cylinder relative to the power source;
- forming a housing having a handle to enclose the power source and the restraining system;
- and
- providing a non-movable adapter constructed to operatively engage the gas cylinder so that connection of the gas cylinder with the non-movable adapter fluidly connects the gas cylinder to the welding-type apparatus and provides gas flow therebetween.
2 more elements
A welder-type device comprising:
- a housing having an opening to allow passage of a gas cylinder therethrough, the opening having a shape and a size dimension substantially conforming to a shape and a size dimension of the gas cylinder;
- a means for supplying welding power located in the housing;
- and
- means for retaining the gas cylinder within the housing.
