A-1 INST ALLA TION WELDMARK 225 A-1 WELDMARK 225 TECHNICAL SPECIFICA TIONS - Weldmark 225 (K2239-4 ) INPUT - GASOLINE ENGINE RA TED OUTPUT @ 104°F (40°C) FOR WELDER HEIGHT WIDTH DEPTH WEIGHT 30.
A-2 INST ALLA TION A-2 SAFETY PRECAUTIONS MACHINE GROUNDING Because this portable engine driven welder or genera- tor creates it’s own power, it is not necessary to con- nect it’s frame to an earth ground, unless the machine is connected to premises wiring (your home, shop, etc.
3. Proper placement of the equipment on the trailer to insure stability side to side and front to back when being moved and when standing by itself while being operated or serviced. 4. Typical conditions of use, i.e., travel speed; rough- ness of surface on which the trailer will be operated; environmental conditions.
WELDING OUTPUT CABLES With the engine off, connect the electrode and work cables to the studs provided. These connections should be checked periodically and tightened if neces- sary. Loose connections will result in overheating of the output studs. When welding at a considerable distance from the welder, be sure you use ample size welding cables.
A-5 INST ALLA TION A-5 e. Place the Engine switch in the “Auto Idle” position. f. Adjust the wire feed speed at the LN-15 and adjust the welding voltage with the output “CONTROL” at the welder. Output “CONTROL” must be set above 3. Note: LN-15 Control Cable model will not work with the WELDMARK 225.
120 V DUPLEX RECEPTACLES The 120V auxiliary power receptacles should only be used with three wire grounded type plugs or approved double insulated tools with two wire plugs. The current rating of any plug used with the system must be at least equal to the current load through the associated receptacle.
A-7 INST ALLA TION A-7 TABLE lll ELECTRICAL DEVICE USE WITH THE WELDMARK 225. Type Common Electrical Devices Possible Concerns Resistive Heaters, toasters, incandescent NONE light bulbs, electric range, hot pan, skillet, coffee maker. Capacitive TV sets, radios, microwaves, Voltage spikes or high voltage appliances with electrical control.
A-8 INST ALLA TION A-8 STANDBY POWER CONNECTIONS The WELDMARK 225 is suitable for temporary, stand- by, or emergency power using the engine manufactur- er’s recommended maintenance schedule. The WELDMARK 225 can be permanently installed as a standby power unit for 240V-3 wire, single phase 38 ampere service.

WELDER CONTROLS - FUNCTION AND OPERA TION ENGINE SWITCH The engine switch is used to Start the Engine, Select High Idle or Auto Idle while the engine is running, and stop the Engine. When placed in the “OFF” position, the ignition circuit is de-energized to shut down the engine.
“ RANGE” SWITCH The “Range” switch is used to select one of three amperage ranges with generous overlap for Stick/TIG welding, or one Wire Feed welding range. Never change the “RANGE” Switch setting while welding. This will damage the switch.
B-3 OPERA TION B-3 ST ARTING/SHUTDOWN INSTRUCTIONS STARTING THE ENGINE Be sure all Pre-Operation Maintenance has been per- formed. Also, read the Engine Owner’s Manual before starting for the first time. Remove all loads connected to the AC power recepta- cles.
B-4 OPERA TION B-4 WELDING PROCESS For any electrodes the procedures should be kept within the rating of the machine. For electrode infor- mation see the appropriate Lincoln publication. STICK (CONSTANT CURRENT) WELDING Connect welding cables to the "TO WORK” and "ELECTRODE” studs.
B-5 OPERA TION B-5 SUMMARY OF WELDING PROCESSES CONTROL ELECTRODE CABLE IDLE WHEN NOT TO START PROCESS USED MODE WELDING WELDING STICK No AUTO Hot Touch electrode to work. Welding starts immediately and engine goes to high idle. WIRE FEED, LN-15 No AUTO Cold Press gun trigger.
C-1 ACCESSORIES C-1 OPTIONAL EQUIPMENT (Field Installed) K957-1 Heavy Duty, Two Wheel Trailer For Small Welders - For road, off-road and in-plant and yard towing. (For highway use, consult applicable federal, state and local laws regarding requirements for brakes, lights, fenders, etc.

Have qualified personnel do the maintenance work. Turn the engine off before working inside the machine. In some cases, it may be necessary to remove safety guards to perform required maintenance. Remove guards only when necessary and replace them when the mainte- nance requiring their removal is complete.
D-2 MAINTENANCE D-2 Use 4-stroke motor oil that meets or exceeds the requirements for API service classification SG or SH. Always check the API SERVICE label on the oil con- tainer to be sure it includes the letters SG or SH. SAE 10W-30 is recommended for general, all-tempera- ture use, -5 F to 104 F (-20 C to 40 C).
